API to get the ms teams channels is failing for azure non admin users.

Question

We are able to get the joined teams for the user. With the team id, we are not able to get the channels for azure normal users. API to get the channels "https://graph.microsoft.com/v1.0/teams/team-id/channels" is failing with the error

{
error: {
code: 'Forbidden',
message: 'Failed to execute Skype backend request GetThreadRequest.',
innerError: {
date: '2020-07-29T21:09:30',
'request-id': '3c6e8d8a-fdff-433b-877e-c785690837f5'
}
}
}

Note: It is working fine for azure admin users. And we provided the Directory.Read.All, Group.ReadWrite.All delegated permission for the registered authentication app in azure. And we also granted the admin consent for those permissions.

We could n't understand why this happens? We are facing this issue in our production environment. This turning out to be a showstopper for us. Could you please take it as high priority and help us solve the issue?

Answer

@Rajesh Rajan , Thank you for reaching out. For the following API to work, you need to use a work or school account to login and get a token for the user using the Auth-Code Grant Flow. More details on this api can be found here: https://video2.skills-academy.com/en-us/graph/api/channel-list?view=graph-rest-1.0&tabs=http
