Hi @nachiketlonkar 

Would you please explain the reason for using the client credentials grant flow?   At Fitbit it is used for very specific use cases, none of which are collecting user data.

The client credentials endpoint documentation states "This authorization flow is used with specific Fitbit API endpoints related to business operations. It is not supported by the public Web APIs to retrieve Fitbit user data."   Therefore, you will not be able to get the user's data with this authorization flow.   Instead, please try the authorization code grant flow.   Instructions are documented here: https://dev.fitbit.com/build/reference/web-api/developer-guide/authorization/
