Confirming details about the user who has granted your application is often a critical piece of designing an OAuth integration. The Current User resource is available to enrich your application with user data.
Because this resource requires authentication, it will always return information about the user who owns the access token you are sending with the request.
Some fields returned in this response will be deprecated in the near future. Not to worry, the fields documented here will all continue to be available for the duration of the API lifetime. Extra fields, not documented here, are subject to deprecation without further notice.
