The People API is built on HTTP and JSON, so any standard HTTP client can send requests to it and parse the responses.
However, the Google API client libraries provide better language integration and improved security over making API requests through HTTP. 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.
To get started, select the programming language that you are using for development.
