Announcements
I am trying to check if a channel exists under a team. When I create a channel, a group chat is associated with it. I just want to inform the user that if they enter the name of an already existing channel, they will be informed with another adaptive card indicating that the channel exists. I've tried this solution, but I've entered a loop where Power Automate was creating an infinite number of group chats.
Hi @mad95 ,
After you capture the response from the user using an adaptive card, you can use the List Channels action in Power Automate and Check if a Channel with a same displayName exists already.
If the channel Exists , then notify the user by sending an adaptive card else create a New Channel.
If this helps , please give this answer a thumbs up and accept this as a solution.
Thanks,

hi, as you can see from the images, it's exactly what i did(second image first action), but the problem is that i think that the loop condition is wrong, cause it is looping i think for the numbers of channel he sees under the team or something like that
Can't understand the language.
Do not enter the loop try to access the response using the expression.
I hope you are capturing only one Name in a single adaptive card
here's the english version,sorry
Can you send the adaptive card JSON payload instead so that I can test it at my end?
Also what is the trigger of the flow?
{"$schema": "http://adaptivecards.io/schemas/adaptive-card.json","type": "AdaptiveCard","version": "1.0","body": [{"type": "ColumnSet","columns": [{"type": "Column","width": 2,"items": [{"type": "TextBlock","text": "Information Gathering","weight": "Bolder","id": "Title","size": "ExtraLarge"},{"type": "TextBlock","text": "Please provide the name of the Project and the people involved. ","isSubtle": true,"wrap": true,"id": "acInstructions","size": "Large"}]}]},{"type": "Container","items": [{"type": "TextBlock","text": "Prject Name","wrap": true,"size": "Medium"}]},{"type": "Input.Text","id": "acProjectName","placeholder": "{Project Name}"},{"type": "Container","items": [{"type": "TextBlock","text": "People Involved","wrap": true,"size": "Medium"}]},{"type": "Input.Text","id": "acPeopleInvolvedEmail","placeholder": "{People Involved email Address}"},{"type": "Container","items": [{"type": "TextBlock","text": "People Involved 1","wrap": true,"size": "Medium"}]},{"type": "Input.Text","id": "acPeopleInvolvedEmail1","placeholder": "{People Involved email Address}"},{"type": "Input.ChoiceSet","placeholder": "Placeholder text","choices": [{"title": "RFQ","value": "YES"},{"title": "SoW","value": "NO"},],"style": "expanded","id": "acRFQSOW","isMultiSelect": false},],"actions": [{"type": "Action.Submit","title": "Submit"}]}
when keywords are mentioned
do you need something else?
I don't know why your are entering an apply to each loop. But here is my flow image. I have created a flow with manual trigger.
In the Filter Array , on the right hand side , I am using the Project Name to filter that array. And in the condition I am using the length of the filter array.
Hope this helps , if this helps , please give this a thumbs up and accept this as a solution.
what's inside project name var and what's the function in the condition?
