Using new ‘Send a Microsoft Graph HTTP request’ in Power Automate to add members to teams channel

I am building a flow to add members to teams channel using MS teams graph API. I am using a new ‘Send a Microsoft Graph HTTP request’ action in Power Automate. I am owner of app registered in azure and provisioned delegated permission for ChannelMember.ReadWrite.All. Admin has also granted a consent but i am still getting an "Forbidden" error Missing one of the scope permission ChannelMember.ReadWrite.All.

I have tried it using HTTP action but it requires a access token to be passed in header makes it two step process. 1. HTTP action to get access token 2. HTTP action to graph API to add members to team. Also first HTTP action to get access token is using OAuth 2.0 Resource Owner Password Credentials (ROPC) grant, which is not recommended to use in prod for security reason as it requires to pass password in body and bypasses MFA.

Does ‘Send a Microsoft Graph HTTP request’ action support adding member in the context of user running flow? Any suggestion?

Are you using the regular ‘Send a Microsoft Graph HTTP request’ or the one with EntraID? For what you want it should be the Entra ID version.

Also, have you tried either the Groups or Teams versions of the Send an HTTP request

What does the Graph call you are trying to make look like?

Hello @SP-27111853-0,

the last time I checked it wasn't possible to add members to private channels with the Invoke an HTTP request action, I had to use the generic HTTP request as I explained in this article.

In response to @Pstork1 -

I am trying to invoke a request using Microsoft graph api to search a Sharepoint list. I am trying to skirt using a premium connector so that It can be called from a power app where every user won't have a premium license.

My question is can I use the Sent HTTP request v2 (Office 365 Groups) to do the same thing as Invoke an HTTP request using (HTTP with Microsoft Entra ID)

Thank you,

Cody
