Validating a email address in java
If you want to explore this protocol interactively, we recommend the Google OAuth 2.0 Playground.To get help on Stack Overflow, tag your questions with 'google-oauth'.The server flow allows the back-end server of an application to verify the identity of the person using a browser or mobile device.The implicit flow is used when a client-side application (typically a Java Script app running in the browser) needs to access APIs directly instead of via its back-end server.Let’s now go the manual route and set things up programmatically: annotations and APIs.An implementation of this the concepts in this article can be found in the Git Hub project.If you need to implement an implicit flow, we highly recommend using Google Sign-In.

You can also use the API Console to create a service account, enable billing, set up filtering, and do other tasks. You need OAuth 2.0 credentials, including a client ID and client secret, to authenticate users and gain access to Google's APIs.
To find your project's client ID and client secret, do the following: For your users, the OAuth 2.0 authentication experience includes a consent screen that describes the information that the user is releasing and the terms that apply.
This document describes our OAuth 2.0 implementation for authentication, which conforms to the Open ID Connect specification, and is Open ID Certified.
The documentation found in Using OAuth 2.0 to Access Google APIs also applies to this service.
This document describes how to perform the server flow for authenticating the user.
