Questions tagged [google-oauth-java-client]

For questions about the use of the Google OAuth Client Library for Java.

The Google OAuth Client Library for Java provides Java classes and methods for both OAuth 1.0a and OAuth 2.0.

This library allows a Java application to gain permission from a user to access the personal data they store with an OAuth provider such as Twitter, Facebook, Instagram, and many others. The user is directed by the OAuth library to the provider site and must confirm to the provider that they are happy for the requested information to be shared. If permission is granted then an access token is made available to the OAuth library and requests for the granted information can be made successfully.

See for more information about the OAuth standards.

This tag should be used for questions about writing Java software which uses the Google OAuth Client Library for Java, for either OAuth 1.0a or OAuth 2.0.
