Client libraries
The Google Wallet API is built on HTTP and JSON, so any standard HTTP client can send requests to it
and parse the responses.
However, the official Google APIs client libraries provide better language integration, improved security,
and support for making calls that require user authorization. The client libraries are available in
a number of programming languages; by using them you can avoid the need to manually set up HTTP
requests and parse the responses.
Note that some of the API client libraries were previously available here as direct downloads.
While these libraries largely contain the same interfaces as the official libraries, they may contain slightly different namespaces which may require updating in your code.
