Libraries

The Google My Business API client libraries support the functionality of the Google My Business API. They provide functionality that's common to all Google APIs, such as HTTP transport, error handling, authentication, JSON parsing, and support for protocol buffers.

If you are new to the Google My Business API, check out the Get Started guides and code samples. For additional information on the client libraries, see Google API Client Libraries.

Prior versions of the client libraries and discovery documents are available on the Previous Versions page.
