dynamically select team channel to post message to in power automate condition

Question

I am trying to set up a flow that posts a message to a particular channel when a form is filled out. The form will specify the channel to post and I want to specify the channel dynamically. I can get it to work if I hard code the channel id, but I want it to post to different channels depending on values in the form.

The image below shows the control. The "Channel id" should be chosen based on a value in the form, the value is the name of the channel, but that will throw an error. Is there a way to dynamically select a channel id here? Is there a specific format or an internal specification or string?

Thanks

Hi @Christopher Muir ，

You can try to enter Custom Values in the 'Post a message in a chat or channel' and pass your dynamic values. The following picture shows the result for your reference:

If you don’t know how to get the Channel ID, you can get Teams address in your Teams and channel ID can be seen it. For example:

URL:
https://teams.microsoft.com/l/channel/19\*\*\*\*%3a\*\*\*\*3151da3802ea43cd8701a6faf4215978\*\*\*\*%40\*\*\*\*thread.skype/testi?groupId=a4c77160-21b4-4169-a683-5362475cf123&tenantId=1ffaf751-2c9b-46b8-a71b-845cf8b15f69

Just replace the parts marked strong(%3a, %40) with " : " and " @ " you get a valid channel-ID:

19:3151da3802ea43cd8701a6faf4215978@thread.skype

Hi @Christopher Muir ,

To do this dynamically, you could also get a list of available chats using "List group chats". Then look for the chat topic you want to send to and use the chat ID associated with it.
