Authorize your app to use Google APIs and data.
Call Google APIs
Use OAuth 2.0 and our Client libraries to quickly and securely call Google APIs.
Google supports common OAuth 2.0 scenarios such as those for web server, client-side, installed, and limited-input device applications.
Get your app verified and ready for production.
Share data with Google apps and devices
Integrate your services and APIs with Google, share media and data with Google Assistant, Smart Home, YouTube and more. After obtaining user consent securely link an individual Google account with an account on your platform with OAuth 2.0 standard flows.
Improve user privacy with custom scopes, sharing only the data necessary for a specific use case. Increase user trust by clearly communicating how Google uses this data.
