Issue with Create Private Channel via Power Automate?

I'm creating a flow to provision Teams with a certain structure, a template, but when I get to the point of creating the private channel there is no way to get it right. I'm always trying to do the same using the graph explorer but when I paste the json body in power automate there's an error message.

This is the code that works in the Graph Explorer:

POST https://graph.microsoft.com/beta/teams/{group_id}/channels
Content-type: application/json

{ "membershipType": "Private",
 "displayName": "Confidential info",
 "members":[{ 
 "@odata.type":"#microsoft.graph.aadUserConversationMember",
 "user@odata.bind":"https://graph.microsoft.com/beta/users('<userID>')",
 "roles":["owner"]
 }]
}

and this is the request body according to the documentation:

POST https://graph.microsoft.com/beta/teams/{group_id}/channels
Content-type: application/json

{
 "@odata.type": "#Microsoft.Teams.Core.channel",
 "membershipType": "private",
 "displayName": "My First Private Channel",
 "description": "This is my first private channels",
 "members":
 [
 {
 "@odata.type":"#microsoft.graph.aadUserConversationMember",
 "user@odata.bind":"https://graph.microsoft.com/beta/users('{user_id}')",
 "roles":["owner"]
 }
 ]
}

I added the code from graph explorer directly to a flow but when I run it the following error message appears:

{
 "error": {
 "code": "BadRequest",
 "message": "channel cannot be null.\r\nParameter name: channel",
 "innerError": {
 "request-id": "<id>",
 "date": "<date>"
 }
 }
}

Any ideas?

Thanks!

hi @VictorIvanidze @efialttes I have already followed the advice in that website without any luck. As I commented I have accomplished creating a new channel through Graph Explorer but the same code fails when running a flow...

Have you tried it even with a basic flow? Do you see anything missing in the http request?

@VictorIvanidze this is the whole flow. I also add an image of the error step and message.

In fact I've tried a few approachs:

- @odata.bind as a string inside a variable
- the whole json inside a variable
- the double @ sign in front if odata.bind

all of them with no positive results

Hi!

Haven't tried myself but this article describes a similar successful scenario

Now, in the article's comments thread a similar issue is described

Hope this helps
