This is more than likely related to the set up for permissions on the Microsoft side. Take a look at these links to confirm that the Microsoft App is set up correctly.

Hi @GuruR ,
It seems like there is an issue with authorization. It is unable to validate the auth key. If you have used anything from below.
1. API Key: It will be in the endpoint specifying the apiKeyId
2.HTTP Header's : Authorization and content-type, you need to specify the authorization and content type in HTTP headers, shown in below
there may be some content that needs to be added in request body.
3. OAuth2.0 then, configure the OAuth profile properly and carefully check when the token is generated and how it being getting accessed. Verify the OAuth configuration and click the 'Get OAuth Token' link to request a new token and check for how much it is valid.
Finally check if the HTTP method is working.
Thanks,

Hi @GuruR ,
It seems a mismatch or misconfiguration in your integration setup. Ensure that the token's audience (aud), tenant ID (tid), and scopes (scp) match your app's configuration. Also, verify that the API endpoint you're calling is correct and accessible. For more details, refer to the Microsoft Teams authentication troubleshooting guide - https://support.microsoft.com/en-us/office/why-am-i-having-trouble-signing-in-to-microsoft-teams-a02...
