Add members to private channel from power automate

[BinuThomas]

Hi All,

Is there a way we can add members to private channel from power automate (when a username is added to a SharePoint list).

I could find a way to call Graph Api to create a private channel and add user at once. but how to add users after creating a channel?

I wonder if below code is for this purpose?

Add conversationMember - Microsoft Graph v1.0 | Microsoft Docs

I tried but getting timeout and this message "Failed to execute request."

Hi @BinuThomas,

I would use the Add member to channel method:

https://docs.microsoft.com/en-us/graph/api/channel-post-members?view=graph-rest-1.0&tabs=http

When the user is already part of the team you can use a HTTP action setup like below:

I tried this one without header, it timed out on testing and got the message "Failed to execute request". I will try with header.

Hi @Expiscornovus 

This worked. Thank you for the help.

Hi,

firstly, thanks for the great solution - it´s working almost 😉

I´d like to add, that I had to add a few more permissions in AAD in regards to Lee´s article.

Now I have the following - and hopefully last - issue:

"Operation not supported for this Channel"

Any idea what has to be done here?

Nevermind - I used a wrong ID for the actions (ID of public channel, not private)

Hi guys, 

How would this look like if you want to use this method to add a member to a shared channel?
You don't want/need to add the user to the team

Hi! I know your solution uses the HTTP action, but I was running into an issue with authentication. I'm using Invoke an HTTP request (HTTP with Azure AD) to try and get around that. It SEEMS to be working, but I'm getting a 400 error. 

{
    "host": {
        "connectionReferenceName": "shared_webcontents",
        "operationId": "InvokeHttp"
    },
    "parameters": {
        "request/method": "POST",
        "request/url": "https://graph.microsoft.com/v1.0/teams/40000000-2000-4000-a00-b000000000/channels/19%3A600000000000000000000000000050%40thread.tacv2/members",
        "request/headers": {
            "Content-type": "application/json"
        },
        "request/body": "{\"@odata.type\": \"#microsoft.graph.aadUserConversationMember\",\n\"roles\": [],\n\"user@odata.bind\": \"https://graph.microsoft.com/v1.0/users('40000000-8008-4000-8000-90000000000')\"}"
    }
}

That is the sanitized raw input from the flow. I can run it successfully from the Graph Explorer so I'm stuck on why it's not working in PowerAutomate. Any ideas?

Hi @Anonymous   I'm running into a similar issue with the HTTP with Azure AD connector in power automate.  I can create the private channel but I can't change or add a owner.  See here for more information: https://powerusers.microsoft.com/t5/General-Power-Automate/Add-user-to-Microsoft-Teams-Channel-private-using-Microsoft-Flow/m-p/2414335/emcs_t/S2h8ZW1haWx8bWVudGlvbl9zdWJzY3JpcHRpb258TE80MEgzUzNGVVNETUV8MjQxNDMzNXxBVF9NRU5USU9OU3xoSw#M144047

I think it's with the connector but I'm not sure.  Thanks in advance

Hi all, just a FYI my flow was corrupt and that's what was causing my problem.

I'm trying to use your example to add members to a private teams channel i made, but i am getting a forbidden error.  do i have the HTTP instructions set up correctly?  should my channel id look something like this?  00%0xx000000xxx0x0xx0x000000000xxx000%00thread.skype

i have emails on my excel tables and was trying to feel those directly, but then also tried to pull the user profile and use the ID.  neither seems to work.

thanks,

The doc shows that authorization is required - anyone get that to work?
