Hi @Karlyn G

The /me endpoint represents the logged-in user, and the context with user participation is a delegated context, so you must grant delegated permissions to your application and use a delegated authentication flow to obtain an access token, such as the auth code flow or ROPC flow.

If your context is an unattended context that only supports application permissions, then you should change the /me endpoint to the /users/{user id} endpoint.

Hope this helps.
