Create Incoming Webhooks

Important

Microsoft 365 Connectors (previously called Office 365 Connectors) are nearing deprecation, and the creation of new Microsoft 365 Connectors will soon be blocked. For more information on the schedule and how the Workflows app provides a more flexible and secure experience, see retirement of Microsoft 365 connectors within Microsoft Teams.

How can you create a webhook in Teams?

If you've already built Office 365 Connectors:

  • Create a Power Automate connector: Power Automate enhances the widely used Workflows apps in Teams. It's the scalable and secure approach to transmit data programmatically into and out of Teams. If you adopt this method, you can create workflow templates for posting alerts from your product to Teams channels. This approach simplifies user adoption of the new method. For more information, see Power Automate for enterprise developers, ISVs, and partners.

  • Update your Teams app: You can enhance your current Teams app. For example, you can enable users to set up proactive messages based on trigger events within your system. For more information, see how bots can post to channels through proactive messages.

Known issues

  • Workflows app can't post in private channels as a flow bot. However, it can post on behalf of a user.
  • Workflows support Adaptive Cards only. It doesn't support the older message card format that Office 365 Connectors use. The support for the use of message card format within Workflows becomes available from mid-October. For more information, see how to convert connector message card format to Adaptive Card.
  • Workflows don't offer third-party connectors such as DataDog and Jenkins.
  • Workflows can only be created in your default environment.

Limitations

Workflows are linked only to specific users (referred to as owners of the workflow) and not to a Teams team or channel. Workflows can become orphan flows in the absence of an owner if no co-owners assigned. To maintain continuity in the business process automated by the flow, admins can add one or more co-owners and grant them full control over the workflow. They can also add authentication for connections, if any, and enable the flow if it has been disabled. For more information, see manage orphan flows.

An Incoming Webhook lets external applications share content in Microsoft Teams channels. The webhooks are used as tools to track and notify. The webhooks provide a unique URL to send a JSON payload with a message in card format. Cards are user interface containers that include content and actions related to a single article. You can use cards in the following capabilities:

  • Bots
  • Message extensions
  • Connectors

Note

Key features of Incoming Webhooks

The following table provides the features and description of an Incoming Webhook:

Features Description
Adaptive Cards using an Incoming Webhook Adaptive Cards can be sent through Incoming Webhooks. For more information, see Send Adaptive Cards using Incoming Webhooks.
Actionable messaging support Actionable message cards are supported in all Microsoft 365 groups including Teams. If you send messages through cards, you must use the actionable message card format. For more information, see Legacy actionable message card reference and message card playground.
Independent HTTPS messaging support Cards provide information clearly and consistently. Any tool or framework that can send HTTPS POST requests can send messages to Teams through an Incoming Webhook.
Markdown support All text fields in actionable messaging cards support basic Markdown. Don't use HTML markup in your cards. HTML is ignored and treated as plain text.
Scoped configuration An Incoming Webhook is scoped and configured at the channel level.
Secure resource definitions Messages are formatted as JSON payloads. This declarative messaging structure prevents the insertion of malicious code.

Note

  • Teams bots, message extensions, Incoming Webhook, and the Bot Framework support Adaptive Cards. Adaptive Card is an open cross-card platform framework that is used in all platforms such as Windows, Android, and iOS. Teams connectors don't support Adaptive Cards. However, it is possible to create a flow that posts Adaptive Cards to a Teams channel.
  • For more information on cards and webhooks, see Adaptive cards and Incoming Webhooks.

Important

You can build a notification bot Teams app using Teams Toolkit other than an Incoming Webhook. They perform similarly but notification bot has more functionalities. For more information, see Build notification bot with JavaScript or Incoming Webhook notification sample.

You can create and send actionable messages through an Incoming Webhook or connector for Microsoft 365 Groups. For more information, see create and send messages.

Note

In Teams, select Settings > Member permissions > Allow members to create, update, and remove connectors, so that any team member can add, modify, or delete a connector.
