Questions tagged [google-oauth]

Google APIs use the OAuth 2.0 protocol for authentication and authorization. Google supports common OAuth 2.0 scenarios such as those for web server, installed, and client-side applications. When posting questions, it is most helpful if you could explain who owns the resource that is to be accessed.

Google OAuth 2.0 is a relatively simple protocol. To begin, you obtain OAuth 2.0 credentials from the Google Developers Console. Then your client application requests an access token from the Google Authorization Server, extracts a token from the response, and sends the token to the Google API that you want to access.
