Hi @SaiRT14,

I am stuck at authorization. This is what I have current and used a public audience link from MS Doc. But it is throwing error of incorrect audience. What shall I use?

Hi PurpleMe ,

Use the Microsoft Graph API with an HTTP action. The Graph API allows you to programmatically create tabs in a Teams channel, including file or library tabs.

Configure:

API Permissions: Ensure your app in Azure AD has the appropriate permissions for the Microsoft Graph API: Delegated or Application Permissions: TeamsTab.ReadWrite.All for managing tabs in Teams. Grant admin consent for the permissions in the Azure portal.

Authentication: Set up an HTTP action with authentication using either: Bearer Token: Use an access token from an OAuth flow. Azure AD Connector: If available, use this to simplify token management.

Channel ID and Team ID: Obtain the Team ID and Channel ID where the tab will be created.

HTTP Action Setup: https://graph.microsoft.com/v1.0/teams/{teamId}/channels/{channelId}/tabs

HTTP Body for File or Library Tab: {
"displayName": "Files",
"teamsApp@odata.bind": "https://graph.microsoft.com/v1.0/appCatalogs/teamsApps/com.microsoft.teamspace.tab.files.sharepoint",
"configuration": {
"entityId": "Documents",
"contentUrl": "https://contoso.sharepoint.com/sites/YourSiteName/Shared%20Documents",
"removeUrl": null,
"websiteUrl": "https://contoso.sharepoint.com/sites/YourSiteName/Shared%20Documents"
}
}

Authenticate the HTTP Action: In the HTTP action in Power Automate: Set Authorization to Bearer. Use a valid access token for the Microsoft Graph API.
