Auto approve a join request

Hi everyone,

 

we´re currently trying to auto approve join requests for Microsoft Teams.

I just checked the whole process and found out that through this link you can send a POST approval which is accepting the invite.

 

https://teams.microsoft.com/api/mt/emea/beta/teams/joinRequestAdminAction?silentAction=false

 

The Body included in this POST:

 

{"GroupId":"123","UserMri":"1:orgid:123","ActionType":"Accept"}

 

 However when I´m trying to do this on my own with an "authorized user" I´m getting the error message "Unauthorized".

 

Anybody a idea?

  • Hi belasor ,

     

    That's an internal API used by the Teams UI, it's not documented and realistically you'll struggle to achieve authentication for any other process to call it. There is an unofficial powershell that tries, but it's majorly unsupported.

     

    The official supported apis for Teams are at graph.microsoft.com. There isn't an api to specifically approve a request, but you can just add a member, this would clear the pending request anyway. See Add member to team - Microsoft Graph beta | Microsoft Docs.

     

    I'm not sure I really see what you are trying to achieve, why not make the group Public then there simply isn't a need for a user to be approved or added, they just join immediately.

        Hi StevenC365 and ChrisWebbTech,

         

        thank you both for the reply.

         

        So the problem we have is a little bit complicated. We have a few users within the company which we want to exclude from all public Teams. Unfortunately we couldn´t find anything to resolve that problem.

         

        An idea was to auto approve all join requests for teams and just reject all requests from people which are part of group "forbidden".

         

        We´ve tried a lot, sensitive labels for groups, Graph API and looking through azure but we couldn´t find anything.
