Posting a message when planner task is completed.

[moraleseder]

I have a flow set-up that creates task in Planner out of messages in a Teams channel. I'm trying to create another flow that when the task gets marked as completed, a reply is posted to the message the task was created from. I've looked around and have tried different suggestions but have not been successful, any help would be greatly appreciated. Here is a screenshot of what I have so far.

Hello @moraleseder ,

when you check the 'Post a reply to a message' action, it needs 'message ID', not content of the message.

Unless you have the original message ID stored somewhere in the Planner task, you must search for it. That means 'Get messages' from the channel to get all posted messages. Among them, you want to find the one corresponding to the Planner task.

If the Planner task has the whole message in the title, you'll use 'Filter array' to get only the message whose 'content' is equal to Planner task title. Then you can use the message ID from this message to post a response.

Wow that worked perfectly!!

Now the last step is that I want the "Completed" message to be posted by the user that actually marked the task as completed. 
Currently, all responses are being posted by me since I'm the one that created the flow (I'm assuming).

Any ideas?

It's not possible, Power Automate will use the selected Teams connector for all actions related to Teams, and the connector is fixed in the flow. It'll be always one user who'll post all the responses (and use all the other connectors to Planner, SharePoint,...), and it's you by default since you created the flow.

You could check in your organization if it's possible to get some separated account that you'll use for those automated actions, otherwise it'll be always you (or some other colleague of yours whose connector will be used).

Thank you very much for all your help!

Hello, came across this thread and am trying to implement this flow in 2022.

Has reply with a message in a channel replaced "post a reply to a message (V2)"?

Hello @Serdotty ,

yes, it did.
