Send Teams Activity Feed notification from Power Automate using custom Teams Bot

Activity feed notifications appears in the Teams activity feed panel with link to various locations thus enabling developers to build actionable content. These notifications are sent as push notifications in the Teams client. In this blogpost, let us see how to send Teams activity feed notification using

  1. Custom Teams App with a Bot
  2. Power Automate standard action: Post a feed notification


Custom Teams App with a Bot:

Microsoft graph has API endpoints to send activity feed notifications to Teams users. The pre-requisite to use the activity feed graph endpoint is to have a custom Teams app scoped to a Team, or in a chat or user.

Step 1: Custom Teams App scoped to Team:

For this blogpost, I have used a custom Teams app scoped to a Team. Refer to the following blogpost to create a custom Team app scoped to a Team with a Bot capable of sending an Adaptive card message on a channel

Do not install the Teams App yet before completing the other steps given below. After the Teams bot is created, a custom Azure Active directory Application must be registered.

Step 2: Azure AD Application – Microsoft Graph Activity Feed permission:

Register an Azure AD application to add the Microsoft Graph permission to be send activity feed. Copy the Application (client) ID and Tenant Id of the registered app from the Overview section and create a secret from the Certificates & secrets under Manage blade per the screenshot shown below. Once the secret is created, copy the value to be used in the Power Automate cloud flow

Add the application permission TeamsActivity.Send with an admin consent.

Step 3: Link the AD app to the Teams App

The AD application with permission to send activity feed is created, the next step is to link the Teams app created in Step 1 with the AD app. In the Teams Developer portal, enter the Application (client) ID in the apps Basic Information under the Overview section as shown in the below screen shot

Don’t forget to Save the App in the Developer portal after the Application ID is entered. Now go to the App Features and then click Activity Feed notification as shown below

Click + Add an activity and enter the following information per the screenshot below

Type: informationBroadcasted

Description: Information Broadcasted Activity

Title: Notification from {actor} broadcasted by {broadcastedBy}

Click Save. The Teams app is now ready to be installed, follow the instructions here to install the bot in a Team for testing the Activity Feed notifications.

Power Automate Cloud Flow to send Adatpive card message and Activity Feed:

The Teams app is ready and now let’s create an Instant cloud flow with manual trigger to send an Adaptive card message to a Teams channel (General or any standard channel) and then Deep link to the adaptive card post in the Teams Channel to the activity feed notification.  I have used a Premium HTTP connector action to send the adaptive card using Bot Framework REST API. Go through the following post to send the Adaptive card

In the flow after the action HTTP-SendAdaptiveCardMessage, add a compose action with the following expression to get the Message ID of the Adaptive card channel message


Add two compose action to store the TeamIdorGroupId and TeamChannelID as shown below

Add a HTTP action (Premium) to send the activity feed to all Team members (Beta) using the Graph Activity Feed API. Find the details below for the HTTP request

Type: POST


Replace teamIdorGroupId from the compose action


  "topic": {
    "source": "entityUrl",
    "value": "{outputs('Compose-TeamIdorGroupId')}/channels/@{outputs('Compose-ChannelID')}/messages/@{outputs('Compose-MessageId')}"
  "activityType": "informationBroadcasted",
  "previewText": {
    "content": "Urgent Information"
  "recipient": {
    "@odata.type": "microsoft.graph.teamMembersNotificationRecipient",
    "teamId": "@{outputs('Compose-TeamIdorGroupId')}"
  "templateParameters": [
      "name": "broadcastedBy",
      "value": "Mohamed Ashiq Faleel"

If you are having issues (Invalid Expression) while saving the flow, add additional @ keyword in the recipient as shown below

Click Show advanced options in the HTTP action to enter the Authentication details. Enter the Client (Application) ID, Secret and Tenant Id from Step 2

Time to test the Power Automate flow. Find below the Activity Feed message for a Teams user


The Teams app can also be enabled with Resource Specific Consent, to do so in the Teams Developer portal click Permissions on the Left bar. In the section Team Permissions select TeamsActivity.Send.Group under Application. If you have done this, Step 2 is not required. I will cover this in a different blog post.

Power Automate standard action: Post a feed notification:

There is a standard Teams action Post a feed notification which creates an activity feed with/without Deep link to a chat or Teams Channel using the Power Automate Teams Bot. Find below the action


Isn’t this powerful to have engaging and actionable content for the users in Teams. There can be many use cases which could be applied for this setup e.g: Notify user and deep link to a Power App added in Teams channel etc. Hope you have found this informational & thanks for reading.

Send Teams channel message aka proactive message using custom Teams bot and Power Automate – Part 2

In the last post, we have seen till the installation of the Teams App with the Bot on a Microsoft Team. Let us now continue to send a proactive message, be it an Adaptive card or a simple Text message on a Teams channel using Bot Framework REST API from a Power Automate Cloud Flow.

A proactive message is any message sent by a bot that isn’t in response to a request from a user. Ex: Welcome messages, Notifications, Scheduled messages, Broadcast message etc

Power Automate Cloud Flow:

For this blog post, I have used a Power Automate Instant cloud flow with manual trigger to send the message to a Teams Channel. To follow along the blog post, be ready with the following information

  1. Team ID & Channel ID

This information is required to send the proactive message to a Microsoft Team Channel. To get this information, in Microsoft Teams Client identify the Team channel in scope > Click the ellipsis of the channel in scope > Get link to channel as shown below

After decoding the channel link, the url will be in the format as shown in the below image from which you can get the channel Id and Team group ID

If you are building a Teams broadcaster or communicator application using Power Apps, these information can be stored in Table or a SharePoint list. There are Graph API endpoints which can used to get the Channel Id’s etc.

  1. Bot ID [Part 1 – Step 6]
  2. Bot Secret [Part 1 – Step 7]
  3. Teams Service URL

The service URL is the base URI for all Bot framework API requests. In Teams the service URL will change based on user’s region [EMEA, America, APAC, India etc]. This example delivers messages only on the Team channel and not to the users directly so you can choose the service URL based on the Microsoft 365 Tenant Location. Find below some URL’s based on region

RegionService URL

All the required information is now available to proceed with sending the channel message using REST API.

Generate Access Token – Bot Framework REST API:

There are SDK’s in Bot Framework for programming languages like .NET, JavaScript, Python etc to handle all conversations for you but an alternative to using the SDK is leveraging Bot Framework REST API. The first step in using the different REST API endpoints from Bot Framework is to generate an access token which is then added to the Authorization header of each API request in this format

Authorization: Bearer ACCESS_TOKEN

To request an access, make a HTTP request per the following details

Method: POST

Request URL:

Content-Type: application/x-www-form-urlencoded



Replace the botId and botSecret with the values stored from the previous steps. The Bot Id and the secret are from the custom Teams app created based on the previous post.

Add a HTTP Action in your Power Automate flow to add the above details for generating the token

The JWT access token is valid for 24 hours, if the token expires make another request.

Send Teams Channel Message:

The Teams Channel conversation post or proactive message on a channel can now be sent using the REST API to Create Conversation with the access token generated in above step.

Simple Text Message:

Find below the HTTP request detail to send a simple proactive message on a Teams Channel. The conversation Id is the Teams Channel Id

Type: POST

Request URL:

Replace teamsChannelId (conversationId) with the actual Team channel Id


  "type": "message",
  "text": "Simple Text Message"

Authorization Header: Bearer access_tokenvalue

The Authentication of the HTTP action should be set to Raw, the value should be in the format

Bearer access_token

You can use Parse JSON Action to extract the access token from the previous HTTP action HTTP-GenerateBOTToken or you can directly get the value using the following expression


The above HTTP request will create a HTTP response with the activity id which can be potentially used to send a reply etc.

Adaptive Card Message:

Adaptive cards are platform-agnostic snippets of UI authored in JSON that different Microsoft apps and services like Teams, Outlook can use. It can be designed using the Adaptive Card designer portal. To send an Adaptive to a Teams Channel, everything else remains the same when comparted with above give HTTP request for the Simple Text message except the Body as below

  "type": "message",
  "attachments": [
      "contentType": "application/",
      "content": {
       "msTeams": {
          "width": "full"
        Replace the ADAPTIVE CARD JSON PAYLOAD from the designer portal

You can get the complete body of request from this Link. This method can be used to send the message on any standard channel but not on Private Teams channel, Microsoft has not opened the possibility to send a channel message on private channel using a Bot. Find below adaptive card message posted on the Teams Channel from the Power Automate flow


There are lot of possibilities with the Bot connector service REST API, what I have shown above is only an endpoint to send a message in a Teams Channel. Look at this documentation on the available conversation operations like Reply, Delete, Update conversation etc. Using this approach you can build a Company broadcaster app with the possibility of reaching out to multiple Teams without the user being the member or owner of the Team.
