Add multiple members in MS Teams Channel Using Azure Logic App

I am using Azure Logic App to post a message and call to MS Teams. I can add single user in Teams using the Microsoft learn guide. Now I am trying to add multiple users using the same logic.I found one post that it's possible using array object and then looping it but there are no details in there that I know how to use.

{ "@odata.type": "#microsoft.graph.aadUserConversationMember", "roles": [], "user@odata.bind": "https://graph.microsoft.com/v1.0/users('jacob@contoso.com')" }

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

I tried to create a Initialize Variable with Array type and value of

[ "user1@mscom" "user2@mscom" ]

then setting up For Each with variables('ChannelUsers')

and adding

{ "@odata.type": "#microsoft.graph.aadUserConversationMember", "roles": [], "user@odata.bind": "https://graph.microsoft.com/v1.0/users('items('For_each')')" }

but ending up with an error - Action For each must be a parent foreach scope of Scope "Add_Member" to be referenced by repeatItems or Items functions.

Solution

  • When you initialize the array variable, the array items must be separated by commas:

    Initialize variable

    Then use the For each loop over @variables('ChannelUsers'):

    For each

    Within the loop, you can use the HTTP method with the current item from the For each loop: @{items('For_each')}

    HTTP

    Result:

    Test 1

    Test 2
