I am trying to subscribe to SharePoint library using webhooks. I have all required credentials with permission, and I am getting the access token but when I am trying to subscribe it giving error
Failed to register webhook. Status code: 401
b'Unsupported app only token.'
Hi @Ashish Kalsi
From the error message, it seems that application permissions are not supported yet. Please try to grant the corresponding delegated permissions to the calling app, and then request the access token using a delegated flow with user participation, such as auth code flow or ROPC flow.
Hope this helps.
