Update app manifest for SSO and preview app

Before you update the app manifest (previously called Teams app manifest), ensure your tab app code is configured to enable single sign-on (SSO).

You've registered your tab app in Microsoft Entra ID, and obtained an app ID. You've also configured your code to call getAuthToken() and handle the access token. Now, you must update the app manifest to enable SSO for your tab app. The app manifest describes how an app integrates into Teams.

webApplicationInfo property

Configure the webApplicationInfo property in the app manifest file. This property enables SSO for your app to help app users access your tab app seamlessly.

   Screenshot shows the app manifest configuration.

webApplicationInfo has two elements, id and resource.

Element Description
id Enter the app ID (GUID) that you created in Microsoft Entra ID.
resource Enter your app's subdomain URI and the application ID URI that you created in Microsoft Entra ID when creating scope. You can copy it from the Microsoft Entra ID > Expose an API section.


Use the app manifest version 1.5 or later to implement the webApplicationInfo property.

The application ID URI that you registered in Microsoft Entra ID is configured with the scope of the API you exposed. Configure your app's subdomain URI in resource to ensure that the authentication request using getAuthToken() is from the domain given in the app manifest.

For more information, see webApplicationInfo.

To configure app manifest

  1. Open the tab app project.

  2. Open the app manifest folder.


  3. Open the manifest.json file

  4. Add the following code snippet to the app manifest file to add the new property:

    "id": "{Azure AD AppId}",
    "resource": "api://subdomain.example.com/{Azure AD AppId}"


    • {Azure AD AppId} is the app ID you created when you registered your app in Microsoft Entra ID. It's the GUID.
    • subdomain.example.com is the application ID URI that you registered when creating scope in Microsoft Entra ID.
  5. Update the app ID from Microsoft Entra ID in the id property.

  6. Update the subdomain URL in the following properties:

    1. contentUrl
    2. configurationUrl
    3. validDomains
  7. Save the app manifest file. For more information, see app manifest.

Here's an example of the updated app manifest
  "$schema": "https://developer.microsoft.com/json-schemas/teams/v1.11/MicrosoftTeams.schema.json",
  "manifestVersion": "1.11",
  "version": "1.0.0",

  "configurableTabs": [
      "configurationUrl": "https://contoso.com/Home/Configure",
      "canUpdateConfiguration": true,
      "scopes": [
  "permissions": [ "identity", "messageTeamMembers" ],
  "validDomains": [
  "webApplicationInfo": {
    "id": "bccfbe67-e08b-4ec1-a7fd-e0aaf41a097c",
    "resource": "api://contoso.com/bccfbe67-e08b-4ec1-a7fd-e0aaf41a097c"


During debug, you can use ngrok to test your app in Microsoft Entra ID. In that case, you need to replace the subdomain in api://subdomain.example.com/00000000-0000-0000-0000-000000000000 with the ngrok URL. You'll need to update the URL whenever your ngrok subdomain changes. For example, api://23c3-103-50-148-128.ngrok.io/bccfbe67-e08b-4ec1-a7fd-e0aaf41a097c.

Upload a custom app and preview in Teams
