Microsoft suggests using Power Automate Workflows to post messages to Teams Channels. They also provide built-in templates to facilitate this. However, BizTalk360 recommends to make few changes in workflow templates to ensure seamless integration.

Why customization of the built-in workflow template is necessary?

When using the built-in workflow template, only the workflow owners can see whether the message was posted or not, and what is the reason for failure if it wasn’t posted. BizTalk360 will always receive a general acknowledgement stating that the request to post a message was received, but it does not provide details on whether the message was successfully posted or failed due to an error.

To correctly determine the status of message posting and take appropriate action, we recommend customizing the template as outlined in the following section.

Create Workflow in Microsoft Teams

Follow these steps to create a flow from the Microsoft Teams:

  1. Sign in to Power Automate.

  2. From the left navigation pane, click Create.

  3. Select Instant cloud flow.

  4. Enter a name for the flow.

  5. In the Choose how to trigger this flow search box, search for When a Teams webhook request is received.

  6. Select the trigger and click Create.

Step 1: Initialize Variable

  1. Click the Plus button between the two steps and select Add an action.

  2. In the search bar, type Initialize variable and click the appropriate action.

  3. Provide a Name for the variable, e.g., PostMessageResponse

  4. Set the Type as Object.

  5. Leave the Value field empty.


Step 2: Send each adaptive card and Set Variable

  1. Click on the new action and select the Apply to each and rename to Send each adaptive card

  2. within the Send each adaptive card add the Post message in a chat or channel and select the action

  3. Configure the action:

    • Post as: Flow bot

    • Post in: Channel

    • Team: Select the same Team configured in the trigger.

    • Channel: Select the required Channel.

    • Message: Use the Message variable or configure the message content based on your requirements.

  4. Click Add an action within that step.

  5. Search for Set variable and select the appropriate action.

  6. In the Name field, choose the variable you previously created, i.e., PostMessageResponse

  7. Click on the Value field and then click Add dynamic content.

  8. In the Dynamic Content popup, select the body option under the Post card in a chat or channel section.


Step 3: Return Response

  1. After the Send each adaptive card (Apply to each) step, click New Step

  2. Search for Response and select the appropriate action.

  3. In the status code enter 200.

  4. In the Body field, click Add dynamic content.

  5. In the Dynamic Content popup, select the previously created variable, PostMessageResponse.

  6. Save the workflow.

Note: The Response action is part of the Premium Subscription.


Now the workflow is set up to post messages and return the correct response based on the status of the post.

If you haven't already copied the Webhook URL, click on the first step in the workflow (When a Teams webhook request is received) and copy the HTTP POST URL.


Provide this URL in the BizTalk360 Teams Notification Channel and configure it for Alarms, Automated Tasks, or Reports to receive timely notifications.

Important Notes:

  • Microsoft Teams Channels accept messages only up to 28KB. If the message exceeds this limit, BizTalk360 will send a fallback message by trimming some information and keeping only the essential details.

  • Workflows cannot post messages to Private Channels.

  • Messages can't be posted if the Workflow is turned off in Teams.
