Teams Store validation guidelines

Following these guidelines increases the chances of your app to pass the Microsoft Teams Store submission process. The Teams-specific guidelines complement the Microsoft commercial marketplace certification policies and are updated frequently to reflect new capabilities, user feedback, and business rule changes.

Note

  • Some guidelines may not be applicable to your app. For example, if your app doesn't include a bot, you can ignore bot-related guidelines.
  • We've cross-referenced these guidelines to the Microsoft commercial certification policies and added Do’s and Don’ts with examples from pass or fail scenarios encountered in our validation process.
  • Certain guidelines are marked as Must fix. If your app submission doesn't meet these mandatory guidelines, you'll receive a failure report from us with steps to mitigate. Your app submission passes Teams Store validation only after you've fixed the issues.
  • Other guidelines are marked as Good-to-fix. For an ideal user experience, we recommend that you fix the issues, however, your app submission isn't blocked from publishing on the Teams Store, if you choose not to fix the issues.

Value proposition

This section is in line with Microsoft commercial certification policy number 1140.1 and provides more guidance to developers of Microsoft Teams apps on their offer’s value proposition.

Apps must provide value to the users by enabling them to complete functional workflows that encourage repeated use. Expand the following sections to know more about the value proposition:

Tabs

Tabs must provide value beyond hosting an existing website. [Must fix]

Graphic shows an example of an app with a workflow valuable to channel members within a team.

Graphic shows an example of an app with entire website in an I-frame without any back option.


Notification bots A notification provides value in Teams if:
  1. Posted card or text provides adequate details requiring no further user action.
  2. Posted card or text provides adequate preview information for a user to take action or decide to view further details in a link opening outside Teams.

Apps that provide only notifications with content such as, You have a new notification or click to view, and require the user to navigate outside Teams for everything else don't provide significant value within Teams.

Screenshot shows an example of a notification only bit with inadequate information in the preview.


Message extensions

[Must fix]

Apps that consist of search-based message extension provide user value by sharing cards that allow for contextual conversations without context switching.

To pass validation for a search-based message extension only app, the following are required as baseline to ensure that the user experience isn't broken. A card shared via a message extension provides value in Teams if:

  1. Posted card provides adequate details requiring no further user action.

  2. Posted card provides adequate preview information for a user to take action or decide to view further details in a link opening outside Teams.

App Name

[Must fix]

This section is in line with Microsoft commercial certification policy number 1140.1.1 and provides more guidance to developers on naming their apps.

Expand to know more

An app's name plays a critical role in how users discover it in the Teams Store. Use the following guidelines to name an app:

  • The name must include terms relevant to your users. [Must fix]

  • Prefix or suffix common nouns with the developer's name. For example, Contoso Tasks instead of Tasks. [Must fix]

  • Must not use Teams or other Microsoft product names such as Excel, PowerPoint, Word, OneDrive, SharePoint, OneNote, Azure, Surface, and Xbox that could falsely indicate co-branding or co-selling. For more information about referencing Microsoft software products and services, see Microsoft Trademark and Brand Guidelines. [Must fix]

  • Must not copy the name of an app listed in the Teams Store or other offer in the commercial marketplace. [Must fix]

  • Must not contain profane or derogatory terms. The name also mustn't include racially or culturally insensitive language. [Must fix]

  • Must be unique. If your app (Contoso) is listed in the Teams Store and Microsoft AppSource and you want to list another app specific to a geography such as Contoso Mexico, your submission must meet the following criteria:

    • Call out the app's region-specific functionality in the title, metadata, first response app experience, and help sections. For example, title must be Contoso Mexico. App title must clearly differentiate an existing app from the same developer to avoid end-user confusion. [Must fix]
    • When uploading the app package in Partner Center, select the right Markets where the app is available in the Availability section. [Must fix]
  • App name mustn't lead with a core Teams feature such as Chat, Contacts, Calendar, Calls, Files, Activity, Teams, and Help. The app name doesn't shortens to either Chat, Contacts, Calendar, Calls, Files, Activity, Teams, and Help on install in the left navigation. [Must fix]

  • If your app is part of an official partnership with Microsoft, the name of your app must come first. For example, Contoso connector for Microsoft Teams.

  • The app name mustn't have any reference to Microsoft or Microsoft products. Don’t use Teams or Microsoft, in the app name unless your app is in official partnership with Microsoft. In such an instance, the app name must come first before any reference to Microsoft. For example, Contoso connector for Microsoft Teams. [Must fix]

  • Don’t use parenthesis in naming to include Microsoft products. [Must fix]

  • Developer name must be the same in the app manifest (previously called Teams app manifest) and AppSource. [Must fix]

  • App manifests submitted must be production manifests. Accordingly, app name mustn't indicate that the app is a preproduction app. For example, app name mustn't contain words such as Beta, Dev, Preview, and UAT. [Must fix]

  • The app name in the app manifest and AppSource must match. [Must fix]

Tip

Your app’s branding on the Teams Store and AppSource including your app name, developer name, app icon, AppSource screenshots, video, short description, and website either separately or taken together mustn't impersonate an official Microsoft offering unless your app is an official Microsoft 1P offering.

Duplicate App

  • Apps from the same developer offering the same functionality must share an app listing unless privacy compliance requirements mandate separate app listings or separate app listing are required to support government cloud. You must build into your business logic and publish only one listing. [Must fix]

    • To fulfill multiple regions support requirement, you must build into your business logic and publish only one listing.

    Screenshot shows the passed scenario of region requirement done with logic.

    • To fulfill multiple end-point requirements for on-premises and on-cloud deployment, you must build into your business logic and publish only one listing.

Expand to know more

App content must be suitable for general workplace consumption and follow all restrictions listed in the commercial marketplace certification policies. Content related to religion, politics, gambling, and prolonged entertainment is prohibited. [Must fix]

Your app must enable group collaboration, improve an individual's productivity, or both. Apps intended for team bonding and socializing must be collaborative and designed for multiple participants. The apps mustn't require a substantial time investment of over 60 mins per session or affect productivity. [Must fix]

Content aggregator apps must have a mechanism for users to report an issue or inappropriate content to the app publisher. [Must fix]

Screenshot shows the passed scenario of content aggregator app to report issues.

Similar platforms and services

[Must fix]

This section is in line with Microsoft commercial certification policy number 1140.1.3.

Apps must focus on the Teams experience and not include the names, icons, or imagery of other similar chat-based collaboration platforms or services within the app content or in the app’s metadata unless the app provides specific interoperability.

Feature names

App feature names in buttons and other UI text mustn't use terminology reserved for Teams and other Microsoft products. For example, Start meeting, Make call, or Start chat are feature names in use by Microsoft in Microsoft Teams. If necessary, include your app name to make the distinction clear, such as Start Contoso meeting.

Authentication

[Must fix]

This section is in line with Microsoft commercial certification policy number 1140.1.4 and provides guidance to developers on authenticating their apps with external services.

    • Apps that depend on external accounts or services must provide clear and simple sign in, sign out, and sign up experience. [Must fix]
    • When users sign out, they must sign out only from the app and remain signed in to Teams. [Must fix]
    • Apps that depend on external accounts or services must provide a way forward for new users to sign up or contact the app publisher to learn more about the services and get access to the services. Way forward must be available in the app’s manifest, AppSource long description, and app first run experience (bot welcome message, tab setup, or config page). [Must fix]
    • Apps that require tenant admin to complete one-time setup must call out dependency on tenant admin to configure the app (before any other tenant user can install and use the app). Dependency must be called out in the app’s manifest, AppSource long description, all first run experience touchpoints (bot welcome message, tab setup, or config page), help text as considered necessary as part of bot response, compose extensions, or static tab content. [Must fix]
  • Content sharing experiences: Apps that require authentication with an external service to share content in Teams channels must clearly state in the help documentation (or similar resources) on how to disconnect or unshare content if that feature is supported on the external service. This doesn't mean the ability to unshare content must be present in your Teams app.

Audio

  • If the primary intent of the app is to listen to music, it must support at least one collaborative scope with end-to-end workflow specific to app. For example, sharing of playlist, configuring or pinning playlist, and synchronously listening to music. [Must fix]

  • Apps published with the primary intent of letting users listen to music in Teams are recommended to include collaborative co-listening experience. [Good-to-fix]

  • If your app supports Tabs as a capability, the screenshots showcasing the app in the context of a Teams tab, in app listing, must contain Team’s chrome. [Must fix]

    Screenshot shows the passed scenario of screenshot of tab capability.

Don'ts:

  • Include mockups that inaccurately reflect your app's actual UI, such as showing your app being used outside Teams.

    Screenshot shows the failed scenario of unrelated app functionality in Teams.

Videos

A video in your app listing is one of the most effective ways to communicate why people must use your app. You can add your YouTube or Vimeo video URL that provides the value of your app. Also, as a best practice, we recommended that you add a video that provides the demo or scenario walkthrough of your app. [Good-to-fix]

If you choose to submit a video as part of your app listing in your Partner Center account, ensure that you meet the following criteria:

  • The video must be short, clear, engaging, and of good quality.

  • The video must demonstrate how to set up and use the app.

  • The video must be in a narrative form.

  • The duration of the video must be within 60-90 seconds for a value video and the recommended duration for a walkthrough video is 3-5 minutes. [Good-to-fix]

  • You must turn off advertisements from your YouTube or Vimeo account settings before submitting the video link in the app listing. [Must fix]

  • The video must highlight your app’s functionalities and integration within Teams. [Must fix]

  • The video must be in the format https://www.youtube.com/watch?v=:id or https://youtu.be/:id for YouTube and https://vimeo.com/:id for Vimeo.

    Screenshot shows the failed scenario of video submitted as part of app listing in partner center.

  • The video can be surfaced in the first position of the screenshots or videos carousel in the app details (Teams Store and Admin Center) and AppSource pages. [Good-to-fix]

  • The video on demo or scenario walkthrough must intend to educate users and not to promote your app.

For more information on the criteria for creating an app value video or walkthrough video, see the checklist to create a video.



Privacy policy

[Must fix]

The privacy policy can be specific to your Teams app or an overall policy for all your services.

  • If you use a generic privacy policy template, you must add a reference to services, applications, or platforms in the scope of your privacy policy. You don’t need to specify your Teams app in the scope, if you include a reference to services, applications, and platforms. The app validation process interprets these references to include your Teams app along with your other services or websites.
  • Must include how you handle user data storage, retention, and deletion. You must describe the security controls for data protection.
  • Must include your contact information.
  • Must not include URLs that are broken or for beta or staging purposes.
  • Must not include links to AppSource.
  • Must not require authentication to access privacy policy.
  • Must not include any commerce UI or store links.
  • Must have the same link in the app manifest and AppSource.

Terms of use

[Must fix]

Use the following guidelines to write the Terms of use:

  • Must be specific and applicable to your offering.
  • Must be hosted on your own domain.
  • Must have a secure (HTTPS) link.
  • Access to Terms of use must not require authentication.

Localization

[Must fix]

  • If your app supports localization, your app package must include a file with language translations that display based on the Teams language setting. The file must conform to the Teams localization schema. For more information, see Teams localization schema. [Must fix]

  • App metadata content must be the same in en-us and other localization languages. [Must fix]

  • Supported languages must be displayed in the AppSource app description. For example, this app is available in X (X= localized language). [Must fix]

  • If the user's client settings don't match with any of your additional languages, the default language is used as the final fallback language. Update the localizationInfo property with the correct default language that your application supports. [Must fix]

  • Update the localizationInfo property with the correct default language your application supports or add localized content for app manifest and Partner Center long and short description. [Must fix]

Apps linked to SaaS offer

This section is in line with Microsoft commercial marketplace policy number 1140.5. If you're building a Teams app linked to a Software as a Service (SaaS) offer, ensure that it adheres to these guidelines.

General
  • ISVs must support the ability for multiple users (Subscribers) in the same tenant to manage their own subscription and assign licenses to users in the tenant.
  • The offer must meet all the technical requirements for Teams apps linked to a SaaS offer.
  • The Teams apps linked to SaaS offer must meet all the requirements defined in 1000 Software as a Service (SaaS).
  • subscriptionOffer details mentioned in the app manifest file must be correct. In your app manifest, add or update node subscriptionOffer with value publisherId.offerId. For example, if your publisher ID is contoso1234 and your offer ID is offer01, the value that you specify in your app manifest must be contoso1234.offer01.
  • Linked SaaS offer to the Teams app must be live in AppSource and preview offers aren't accepted for Teams Store approval.

Offer metadata
  • Offer metadata must match across the app manifest, the Teams app listing in AppSource, and the SaaS offer in AppSource.
  • Teams app and SaaS offer must be from the same publisher or developer. The SaaS offer referenced in the app manifest must belong to the same publisher as the Teams app is submitted to the commercial marketplace.
  • As your submitted offer is a Teams app linked to SaaS offer, you must select Additional purchases as Yes, my product requires purchase of a service or offers additional in-app purchases​ in Partner Center product set-up section of your offer listing.
  • Plan descriptions and pricing details must provide enough information for users to clearly understand the offer listings.
  • Any limitations, dependencies on additional services, and exceptions to features offered must be accurately called out in plan descriptions.
  • The Teams apps linked to SaaS offer are designed to support licenses assigned on a named, per-user basis. Sometimes, the SaaS offer is built with other method or has specialized purchase flows. You must clearly mention in the app metadata and subscription plan details about the method and purchase flows.
  • SaaS offer must provide messages and guidance to all users in all applicable states of purchase flow.

SaaS offer home page and license management
  • Provide introduction to subscribers on how to use the product.

  • Allow the subscriber to assign licenses.

  • Provide different ways to engage with support for issues, such as FAQ, knowledge base, and email.

  • Validate users to ensure that they don’t already have license assigned through another user.

  • Notify users after license assignment.

  • Guide users on how to add the app to Teams and get started through Teams chat bot or email.

  • If a SaaS app uses Microsoft license management, after the confirmation of the app subscription on the ISV's landing page, the user must be redirected to the Microsoft license management in Teams to avoid a dead-end and allow the user to manage licenses within Teams.


Usability and functionality
  • After successful purchase and assignment of licenses, you must provide the following:
    • Access to users for subscribed plan features.
    • Value addition and significant benefits of subscription plan to users.
    • From your Teams app, provide link to the SaaS application home page for subscribers to manage the licenses in the future.

Tabs

This section is in line with Microsoft commercial marketplace policy number 1140.4.2. If your app includes a tab, ensure that it adheres to these guidelines.

Tip

For more information on creating a high-quality app experience, see Teams tab design guidelines.


Setup
  • Tab setup mustn't dead-end a new user. Provide a message on how to complete the action or workflow. [Must fix]

    Graphic shows an example of Tab with a dead-end on setup.

  • The user mustn't leave the tab configuration experience inside Teams to create content outside Teams and then return to Teams to pin it. Tab configuration screen must explain the value of configuration and how to configure. [Must fix]

    validation-tabs-set-up-profile-name

  • Tab configuration screen mustn't embed an entire website. Keep your configuration experience focused. For example, if you're building a project management app that lets users configure a project in a channel, keep the tab configuration screen focused on allowing the user to select a project from your app to configure in the channel. [Must fix]

    validation-tabs-setup-configuration-exp

    validation-tabs-set-up-configuration-screen

  • Apps that require users to input a URL while configuring a tab must:

    • Provide an appropriate way forward guidance for the user to acquire or generate the URL. [Must fix]

    • Check for URL that is relevant or appropriate to the app’s functionality as per the app description. [Must fix]

      Screenshot shows an example of tab configuration with a way forward for user to generate a URL.

      Screenshot shows an example of tab configuration without a way forward for user to generate a URL.

  • Hyperlink the contact us information in the configuration screen instead of plain text to help users to contact you for support requirements. [Must fix]

  • For a seamless first run user experience, we recommend that you hyperlink your support URL or email in the configuration screen. [Good-to-fix]


Views
  • The sign in screen area mustn't use large logos. [Must fix]

    validation-views-app-login

  • Content can be simplified by breaking down across multiple tabs.

    val-views-multiple-tabs

  • Tabs shouldn't have a duplicate header. Remove duplicate logos from the I-frame since the tab framework already displays the app icon and name. [Good-to-fix]

    Graphic shows an example of a tab without duplicate headers and logos.

    Graphic shows an example of a tab with duplicate headers and logos.


Navigation

The following are the navigation guidelines:

  • Tabs mustn't provide navigation that conflicts with the primary Teams navigation. If you provide a left navigation in your tab, it mustn't include only icons or icons with stacked text. It mustn't be a collapsible rail with the option to see icons with stacked text (mimicking the Teams navigation bar). Include icons with in line text or only text or use hamburger menus instead of tab left rail. [Must fix]

    Design your app with basic and advanced Fluent UI components.

    Graphic shows an example of navigation in a tab that doesn't conflict with the primary Teams navigation.

    Graphic shows an example of left navigation rail that conflicts with the primary Teams navigation.

  • If your tab has a toolbar on the left rail without any navigation component, the toolbar must leave 20 pixels spacing from Teams left navigation. [Must fix]

    validation-nav-spacing-between-toolbar

  • The secondary and tertiary pages in a tab must be opened in a level two (L2) and level three (L3) view in the main tab area, which is navigated via breadcrumbs or left navigation. You can also use the following components to aid navigation in a tab:

    • Back buttons

    • Page headers

    • Hamburger menus

      Screenshot that shows an example of in-meeting dialog with multiple navigation levels.

  • Deep links in tabs mustn't link to an external webpage but within Teams. For example, dialogs or other tabs. [Must fix]

    validation-nav-view-button-not-linked-static-tab

  • Tabs mustn't allow users to navigate outside Teams for the core app experience. Tabs can redirect outside Teams for non-core workflows. For example, to raise a support ticket. [Must fix]

    validation-nav-core-workflow-within-configuration

    validation-nav-core-workflow-redirects-outside

  • Horizontal scroll mustn't be present in an in-meeting tab. [Must fix]

  • In-meeting dialogs used in your app mustn't allow horizontal scrolling. Use in-meeting dialogs sparingly and for scenarios that are light and task oriented. You can specify the width of the in-meeting dialog’s I-frame within the supported size range to account for different scenarios. [Must fix]

  • Dialogs used in your app mustn't allow horizontal scrolling. Dialogs allow you to select different sizes to make the content responsive without the need of Horizontal scroll. If necessary, you can use a Stageview (a full screen UI component to surface your web content) to complete the workflow without Horizontal scroll. [Must fix]

  • Horizontal scroll present in the tab in a personal chat, channel, and in-meeting details tab in any scope isn't allowed if the entire tab canvas is scrollable, unless your tab uses an infinite canvas with fixed UI elements. [Must fix]

    Graphic shows examples of all the scenarios in mobile where horizontal scroll is allowed.

    Graphic shows an example of horizontal scroll in Kanban board.

    Graphic shows an example of list view with many  components.

    Graphic shows an example of horizontal scroll in a white board with infinite canvas and fixed board.

  • The user must have an option to go to previous work state. [Must fix]

     Screenshot shows back button option available.

    Screenshot shows failed scenario of no back button option available.

  • Horizontal scroll in Adaptive Cards mustn't be present in Teams. [Must fix]

  • Bottom rail used for navigation in tabs mustn't conflict with Teams native mobile app navigation. [Must fix]

    Graphic shows an example of a tab that conflicts with Teams native mobile app navigation.


Usability
  • Content mustn't truncate or overlap within the tab. [Must fix]

    validation-usability-content-truncations

  • Users must be able to undo their last action in the tab. [Must fix]

  • Tabs in a personal context may aggregate content from shared instances of the app. For example, a project management app with a configurable tab that lets channel members comment on the project on Kanban cards, must aggregate this content and display in the personal app. [Good-to-fix]

  • Tabs must be responsive to Teams themes. When a user changes the theme, the app's theme must reflect the selection. [Good-to-fix]

    Graphic shows an example of a tab responsive to a theme in Teams.

    Graphic shows an example of a Tab not responsive to theme in Teams.

  • Tabs must use Teams styled components such as, Teams fonts, type ramps, color palettes, grid system, motion, tone of voice, whenever possible. For more information, see tab design guidelines. [Good-to-fix]

    Screenshot shows an example of a tab with calibri font instead of native Teams font.

  • If your app functionality requires changes in settings, include a Settings tab. [Good-to-fix]

  • Tabs must follow Teams interaction design such as, in-page navigation, position and use of dialogs, information hierarchies. For more information, see Microsoft Teams Fluent UI kit. [Good-to-fix]

  • Tab experiences must be fully responsive on mobile (Android and iOS). [Must fix]

    Tip

    • Include a personal bot alongside a personal tab.
    • Allow users to share content from their personal tab.
  • Tab mustn't contain elements that completely obstruct or impede workflows within the tab. For example, bot inside a tab that can't be minimized. [Must fix]

    Graphic shows an example of tab with elements that impede workflows within the tab.

  • Tab mustn't have a broken functionality. Your offer must be a usable software solution and must provide the functionality, features, and deliverables as described in your listing and other related materials. [Must fix]

  • If your tabs contain a footer, ensure that you remove all links unrelated to app functionality from the footer. [Must fix]


Scope selection
  • Content in the landing page of configurable tabs mustn't be scoped for individual use and not include personal content such as My Tasks or My Dashboard. [Must fix]

    Graphic shows an example of content in a configurable tab with personal scope such as My tasks or My dashboard.

  • After the configuration experience, the landing page must show a collaborative view for the entire team. [Must fix]

  • If your app requires provision of a personal scope view for the user to enhance efficiency or workplace productivity, use filtered views, deep links to personal apps, or navigate to L2 or L3 views within the configurable tab and keep the landing page contextually the same for all the users. [Must fix]

  • Content in the landing page of the configurable tabs must be contextually same for all members of the channel. [Must fix]

    Graphic shows an example of content in the landing page of the configurable tabs contextually different for all members.

  • Configurable tabs must have focused functionality. [Must fix]

Bots

This section is in line with Microsoft commercial marketplace policy number 1140.4.3.

If your app includes a bot, ensure that it adheres to these guidelines.

Tip

For more information on creating a high-quality app experience, see Teams bot design guidelines.


Bot design guidelines
  • Your Teams app must follow Teams bot design guidelines.

  • You must implement a dialog to avoid multi-turn bot response when the workflow involves the user performing repetitive tasks. For example, use a dialog to repetitively capture name, date of birth, place, and designation instead of using multi-turn conversations. [Must fix]

  • Any broken links, responses, or workflows in your app must be fixed. [Must fix]


Bot commands

Analyzing user input and predicting user intent is difficult. Bot commands provide users a set of words or phrases for your bot to understand.

  • All commands that your bot supports must work correctly, including generic commands such as Hi, Hello, and Help. [Must fix]

    Graphic shows an example of bot responding to generic commands.

    Graphic shows an example of bot with no response to generic commands.

  • Bot commands mustn't lead a user to a dead end, the commands must always provide a way forward. [Must fix]

    validation-bot-commands-dead-end

  • You must list at least one valid bot command in the items.commands.title section of the app manifest and add a suitable description that gives clarity to the user on the bot command and its usage. Bot commands listed in the commandLists section of the app manifest surface as prepopulated commands in the bot command menu and provide a way forward for the new user to interact with the bot. [Good-to-fix]

  • Bot response mustn't contain any official Microsoft product images or avatars. Use your own assets in your app. Use of Microsoft product images in your app isn't allowed. You may only copy, modify, distribute, display, license, or sell Microsoft copyrighted product images if you're granted explicit permission within the End-User License Agreement (EULA), license terms that accompany the content, or in the Microsoft Trademark and Brand guidelines. [Must fix]

  • Bots must respond to user commands without displaying a continuous loading indicator. [Must fix]

  • Bot help command response mustn't redirect the user outside Teams. Bot help command response can redirect user to a canvas within the Teams app or provide a way forward response in an Adaptive Card. [Must fix]

    Graphic shows an example of bot response redirecting user outside of Teams.

  • Bots must always provide a valid response to a user input even if the input is irrelevant or improper. [Must fix]

    Graphic shows an example of a valid response for improper bot command.

    Graphic shows an example of an invalid response for improper bot command.

  • Special characters such as slash (/), mustn't be prefixed to bot commands. [Must fix]

    Graphic shows an example of a failed scenario where special characters are prefixed to bot commands.

  • Bots must provide a valid response to invalid user commands. Bots mustn't dead-end the user or display an error if a user sends an invalid bot command. [Must fix]

    Graphic shows an example of bot providing a way forward for an invalid command.

    Graphic shows an example of a failed scenario where a bot sends a same response for a valid and invalid command.

  • Bot functionality must be relevant to the scope in which the bot is installed and the bot must provide value in the installed scope. [Must fix]

  • Bots mustn't contain duplicate commands. [Must fix]

  • Bots mustn't display a typing indicator after responding to the user command, but can display a typing indicator while responding to the user command. [Must fix]

  • Bots must provide a valid response to the help command typed in lowercase or uppercase that provides the user with a way forward or lets the user access the help content related to the bot usage. Bots must provide a valid response even when the user hasn't logged on to the app. [Must fix]

    Graphic shows an example of bot not providing a valid response for a command in lowercase or uppercase.

    Graphic shows an example of a bot without a valid response when the user hasn't logged on to the app.

  • Bots must provide a valid response to help command.

    Graphic shows an example of a bot message without truncating on mobile.

    Graphic shows an example of a bot message truncating on mobile.

  • All the links in a bot response adaptive card must be responsive. Any link that takes the user outside the Teams platform must have a clear redirect text such as, View in.. or This way to.., a pop-out icon in the bot response action button, or have a suitable redirect text in the bot response message body. [Must fix]

    Graphic shows an example of bot response action button with a redirect.

  • By design, if your bot doesn't respond or support any user command and is a one way bot only intended to notify users. You must set isNotificationOnly to true in the app manifest. [Must fix]

    Graphic shows an example of notification only property set to true in the app manifest.

    Graphic shows an example of notification only bot not responding for a user's message.

  • Bot user experience mustn't be broken on mobile platforms. Your bot must be fully responsive on mobile. [Must fix]

Tip

For personal bots, include a Help tab that further describes what your bot can do.


Bot first run user experience
  • A bot in personal scope must always send welcome message or provide prompt starters. [Must fix]

    If you're using prompt starters, ensure the following guidelines are met:

    Prompt starters help users start a conversation with your bot. To enable prompt starters, the commands property in app manifest needs to be defined.

    • The bot must provide at least one command that enables the user to know about the value proposition of the app. [Must fix]
    • Prompt starters or commands must be functional and return responses. [Must fix]
    • Command description must be coherent and clearly communicate value of the command. [Must fix]
    • Prompt starters or commands must be relevant to the app's functionality. [Must fix]
    • The bot must have at least three unique prompt starters or commands. [Good-to-fix]

    If your app sends a welcome message, ensure the following guidelines are met:

    • If the app has a complex configuration flow (requires an enterprise license or lacks an intuitive sign up flow), then bots in such apps must always include configuration related information while sending a welcome message during the first run.

      For best experience, the welcome message must include the value offered by the bot to users, who installed the bot in channel, how to configure the bot, and briefly describe all supported bot commands. You can display the welcome message using an Adaptive Card with buttons for better usability. For more information, see how to trigger a bot welcome message. For apps without a complex configuration flow, you can choose to trigger a welcome message during the bot first run experience. However, if a welcome message is triggered, it must follow the welcome message guidelines.

      Graphic shows an example of bot sending a welcome message when the bot has a complex configuration workflow.

      Graphic shows an example of bot not sending a welcome message when the bot has a complex configuration workflow.

  • Bot welcome messages in channels and chats are optional during first run, especially if the bot is available for personal use and performs similar actions. Your bot mustn't send welcome messages to users individually (it's considered spamming). The message must also mention the person who added the bot.

    validation-bot-welcome-message-not-trigger

    validation-bot-wel-message-trigger

  • Welcome message mustn't dead-end the user. Welcome message must include the value offered by the bot to the users who installed the bot in channel, how to configure the bot, and briefly describe all supported bot commands. You can display the welcome message using an Adaptive Card with buttons for better usability. [Must fix]

    Graphic shows an example of a failed scenario where the bot has no way forward for the user in a welcome message.

    Graphic shows an example of bot welcome message with a clear way forward for the user to complete the task.

  • Bot installed in a channel or group chat scope mustn't send proactive welcome message to all the team members in 1:1 chat. [Must fix]

    Graphic shows an example of bot sending proactive welcome message to all the team members.

  • Notification only bot can send a proactive welcome message in a channel only if the message contains important information for any user to complete the configuration for the bot or clarifies the scenarios when notifications are triggered. [Must fix]

  • Bot installed in a channel or group chat scope mustn't send proactive messages (not just welcome message) that are irrelevant to all users in channel or group chat, instead must send proactive messages to the user over 1:1 chat. [Must fix]

  • Bot installed in a channel or group chat scope mustn't allow users to start individual workflows. Bots must complete individual workflows in 1:1 chat with the user. [Must fix]

  • Bot welcome message must clearly call out the limitations related to bot usage in the installed scope. [Must fix]

    Graphic shows an example of app limitation in bot welcome message.

    Graphic shows an example of a bot without app limitation in a welcome message.

  • Welcome message must auto trigger on app install in a personal scope. If the bot doesn't send a welcome message in a personal scope, the user is lead to a dead-end. If the app doesn't include a complex configuration workflow, it's optional for the developer to trigger a welcome message in the channel or group chat scope. [Must fix]

    Graphic shows an example of bot not sending a  welcome message automatically in personal scope.

  • Welcome messages must trigger only once on bot install. Welcome messages mustn't trigger every time the user invokes the help command. Help command response must be focused to include a way for the user to access help related to the bot. [Must fix]

  • Welcome messages mustn't trigger with every bot command. This is considered spam. [Must fix]

    Graphic shows an example for bot triggering a welcome message for any command.

  • Welcome message content must be related to the bot workflow mentioned in the app’s long description and the installation scope. Welcome message must include the value offered by the bot to users who installed the bot in channel, how to configure the bot, and briefly describe all supported bot commands. [Must fix]

  • Bot mustn't send multiple welcome messages when triggered on app install. [Must fix]

    Graphic shows an example of bot triggering multiple welcome messaged on app install.

  • App name in the welcome message must match the app name in the app manifest. [Must fix]

    Graphic shows an example of app name in welcome message not matching with the app name in the app manifest.

  • Welcome message mustn't display competitor chat based collaborative platform names unless the app provides specific interoperability.

  • Welcome message mustn't redirect the user to another Teams app, instead the welcome message must nudge the user to complete their first task and briefly describe all supported bot commands in the app. [Must fix]

  • Welcome message mustn't contain links to any app marketplace including AppSource. [Must fix]

  • If your app has a complex configuration workflow that requires admin led installation, doesn't have an intuitive and readily available sign up flow, or requires users to complete configuration steps outside the Teams experience and return then the bot must send a proactive welcome message in a team or group chat scope after installation. [Must fix]

  • If your bot sends a welcome message in the channel, it mustn't send it to users individually (It's considered spamming). The welcome message must also mention the person who added the bot. [Good-to-fix]

Tip

In welcome messages to individual users, a carousel tour can provide an effective overview of your bot and any other app features to encourage users to try bot commands. For example, Create a task.


Bot message spamming

Bots mustn't spam users by sending multiple messages in short duration.

  • Bot messages in channels and chats: Don't spam users by creating separate posts. Create a single post with replies in the same thread. [Must fix]

    validation-bot-message-spam-one-message

    validation-bot-message-spam-multiple-message

  • Bot messages in personal apps:

    • Don't send multiple messages in quick succession. [Must fix]

      Graphic shows an example of a bot sending multiple messages in quick succession.

    • Send one message with complete information. [Must fix]

    • Avoid multi-turn conversations to complete a single repetitive workflow. [Must fix]

    • Use a form (or dialog) to collect all inputs from a user at one time. [Must fix]

    • NLP based conversational chatbots can use multi turn conversation to make the discussion more engaging and complete a workflow.

      validation-bot-message-using-task-module

      Graphic shows an example bot using multi-turn messages to complete a single conversation.

  • Welcome messages: Don't repeat the same welcome message over regular intervals. For example, when a new member is added to a team, don't spam the other members with a welcome message. Message the new member personally. [Must fix]


Bot notifications

Bot notifications must include content relevant for the scope you define for the bot (team, chat, or personal). [Must fix]

validation-bot-notification-relevant

validation-bot-notification-not-relevant


Bots and Adaptive Cards

Adaptive Cards are a highly recommended way to display bot messages. The cards must be lightweight and only include up to six actions. To display more content, consider using a dialog or tab.

For more information about cards, see:

Bot experience must be fully responsive on mobile. Bot responses must provide a way forward where applicable. Bot musts be responsive and fail with a graceful error message for failures. Bot messages sent in the personal scope to user's base on triggers in a collaborative scope must provide contextual information (including the message’s origin).


Notification only bots

Apps that consist of notification only bots provide user value by triggering user notifications based on certain triggers or events in the core app or backend. For example, a new sales lead or prospect is added for the sales team to follow up on. A high-quality notification only bot notifies the users regularly on certain event completions such as workflow completions or alerts.

Tip

Preview information and provide basic in line user actions in the posted card so that the user isn't required to navigate outside Teams for all actions (irrespective of complexity).


Bot metadata information
  • Bot information in the app manifest (bot name, logo, privacy link, and terms of service link) must be consistent with the Bot Framework metadata. [Must fix]

  • Ensure that the bot ID in the app manifest matches with bot ID in the last Teams Store published version of your app. Changing bot IDs in an app update leads to permanent loss of all user interaction history with the bot for existing users of your app and starts a new conversation chain with the new Bot ID. [Must fix]

  • Any change to app name, metadata, bot welcome message, or bot responses must be updated with new name. [Must fix]

  • App name in the bot welcome message or bot responses must match the app name in the app manifest. [Must fix]

Message extensions

This section is in line with Microsoft commercial marketplace policy number 1140.4.4.

If your app includes a message extension, ensure that it adheres to these guidelines.

Tip

For more information on creating a high-quality app experience, see the Teams message extension design guidelines.


Messaging extensions design guidelines
  • If your Teams app uses the messaging extension capability, your app must follow the Messaging extension design guidelines.

    Graphic shows an example of an app not meeting extension guidelines.

  • Messaging extensions are shortcuts for inserting app content or acting on a message without navigating away from the conversation. Keep your messaging extension simple and display only the components required to effectively complete the action. Complete website mustn't be I-framed within the messaging extension. [Must fix]

  • Preview images in Adaptive Cards in messaging extensions must load properly. [Must fix]

    Graphic shows an example of preview image loading in adaptive card.

    Graphic shows an example of preview image not loading in adaptive card.

  • Messaging extension response card must include the app icon to avoid end user confusion. [Must fix]

  • Your app mustn't have any broken functionality. App mustn't dead-end or block the user from completing a workflow in a messaging extension. [Must fix]

  • Messaging extensions must respond or work as intended in group chat and channel scopes. [Must fix]

  • You must include a way for the user to sign in or sign out from the messaging extension. [Must fix]

  • Message extensions that use OpenAPI urls must not provide redirection on any API call. Actual API calls must be served from the same domain or subdomain of the root domain.


Action commands for Action-based message extensions

Action-based message extensions must do the following:

  • Allow users to trigger actions on a message without completing intermediate steps, such as sign in.

    validation-messaging-extension-no-intermediate-steps

    validation-messaging-extension-intermediate-steps-available

  • Pass the message context to the next work state. [Must fix]

    validation-messaging-extension-app-passes-messages

    validation-messaging-extension-app-doesnot-pass-messages

  • Incorporate the host app name instead of a generic verb for action commands triggered from a chat message, channel post, or call to action within apps. For example, use Start a Skype Meeting for Start Meeting, Upload file to DocuSign for Upload file. [Good-to-fix]

    Graphic shows an example of host app name for an action command.

    Graphic shows an example of generic verb for an action command.

  • Invoking a message action must allow the user to complete the workflow. Errors, blank responses, or continuous loading indicators to make the message action functional as intended mustn't be present. [Must fix]

    Graphic shows an example of continuous loading indicator when a bot invokes an action command.

  • Duplicate action commands mustn't be present. [Must fix]

  • Message actions must allow the user to complete the workflow as intended without an invalid response. [Must fix]

  • Apps with only action-based messaging extension must have the following end state:

    • Post a relevant action as a notification either in the context where message extension is invoked or in 1:1 bot chat based on user scenario. [Must fix]

    • Allow users to share cards with other users based on the action taken. This is to ensure that apps don't take silent actions. For example, a ticket is created based on a message in a channel, but the app doesn't send a notification or doesn't provide a way to request the user to share ticket details after the ticket is created. [Must fix]


Preview links (link unfurling)

[Must fix]

  • If the app has declared the supportsAnonymizedPayloads property in the app manifest and the user hasn't installed the app, the app link must unfurl and show the add app dialog after the card is selected. [Must fix]

  • Message extensions must preview recognized links in the Teams compose box. Don't add domains that are outside your control (either absolute URLs or wildcards). For example, yourapp.onmicrosoft.com is valid but *.onmicrosoft.com isn't valid. Top-level domains also are prohibited. For example, *.com or *.org. [Must fix]

  • Apps must only declare that are under the app publisher’s direct ownership in the messageHandler link unfurling section of the app manifest. It mustn’t contain *.botframework.com. [Must fix]


Search commands
  • Search based message extensions must provide text that helps the users to search effectively. [Must fix]

    Graphic shows an example of a message extension with help text for users to search effectively.
