Mention a team with a flow

Today I had a couple of queries about mentioning in Microsoft Teams. I revisited the Mention a channel with flow post because of the Invalid request body was sent error. And I also created this new blog about team mentioning.

Original request

I would like to know if it is possible to mention a team in a Teams channel via Power Automate just like the screenshot below.

@mention a Microsoft Teams group in Power automate


Invoke HTTP request approach

Turns out this can still be done by using the Invoke an HTTP request approach.

1. Add an Invoke an HTTP request action. Make sure that in the connection of the action is specified as the base resource url.

2. Use the Send chatMessage in channel method from the Graph API .

Use the code snippet for the body of the request. Replace the IT team name and the id of the team by your name and id.


Happy testing!

    Do we know if/when we could generate an @-mention for a custom tag?

    @Hubert, it should be possible by setting the tag property in the json. I posted another blog about this:

    Too bad this one is a Premium connector though ? I’m on an EDU plan with possibly no hope of really, ever going on to a Premium plan.

    How did you build the Channel Post URL that you reference. I think this is where mine is failing. TIA

    In this example that is a variable of type string. Normally the value of the variable would be something like below:

    Replace the teamid and channelid by the ids of the Team and Channel you want to use.

    Hi Dennis

    First of all great Post!

    I wanted to know if you also can force the activity Notification with mentioning.
    I have done your steps and all working but not showing in activity feed.

    Thanks for your reply.

    Could you post an example json like above with embed image to show on Teams Post ?
