Is there any graph api to grant access to externalUserID for sharepoint files[ files shared in teams channel]?

Does /invite API work explicitly for driveItem?

If I want to grant access to an external user for file sharing in the channel, can we use the same /invite API ? because in this case though /invite API returns 200 success but when I try to fetch permissions of that file .....granted user still dosen't have permission.

I have used the below two APIs for granting access to the team's channel file.

https://graph.microsoft.com/v1.0/sites/{site-id}/drive/items/{item-id}/invite

https://graph.microsoft.com/v1.0/shares/{encoded-sharing-url}/permission/grant

but still, the permissions array is not updated with the new user - https://graph.microsoft.com/v1.0/drives/{drive-id}/items/{item-id}/permissions

    Hi @Satyam Yadav

    You should be able to modify this example:

     POST /me/drive/items/{item-id}/invite  
     Content-type: application/json  
          
     {  
       "recipients": [  
         {  
           "email": "user@externaldomain.com"  
         }  
       ],  
       "message": "Here's the file that we're collaborating on.",  
       "requireSignIn": true,  
       "sendInvitation": true,  
       "roles": [ "write" ]  
     }  
    

    See: https://learn.microsoft.com/en-us/graph/api/driveitem-invite?view=graph-rest-1.0&tabs=http

    Hi @Satyam Yadav ,

    I tested permission grant, able to add external user existing share link created using /drive/items/{id}/invite.
    Screenshot of grantedToIdentities of a driveItem with only 1 external user.

    Using Grant permission able to add another external user, below sample snippet.

    POST https://graph.microsoft.com/v1.0/shares/{encoded-sharing-url}/permission/grant  
    Content-type: application/json  
      
    {  
      "recipients": [  
        {  
          "email": "john@contoso.com"  
        },  
        {  
          "email": "ryan@external.com"  
        }  
      ],  
      "roles": ["read"]  
    }  
    

    Screenshot of my test response body.

    It will work with the sharing links that have "scope": "users".

    Hope this helps.
