Hi @Surya Prakash,
Thanks for reaching out!
I can understand that you are trying to create OnlineMeeting, to execute this query with delegated access (Access on behalf of a signed in user) an app requires access token, please follow authentication and authorization steps to get the access token:
- Register the app with Microsoft Entra ID.
- Request authorization.
- Request an access token.
- Use the access token to call Microsoft Graph.
- [Optional] Use the refresh token to renew an expired access token.
Reference document: https://learn.microsoft.com/en-us/graph/auth-v2-user?tabs=http#authentication-and-authorization-steps
Note: Consent to "OnlineMeetings.ReadWrite
" for delegated access.
To use application permission/App-only access (access without a user) for this API, tenant administrators must create an application access policy and grant it to a user to authorize the app configured in the policy to create online meetings on behalf of that user (with user ID specified in the request path).
Hope this helps.
