The Click2Mail REST API Software Development Kit (SDK) is a set of libraries in several common languages, designed to make working with the REST API simpler by wrapping common functionality into ease-to-use code. Each of these, along with a some other sample code, can be found on the Click2Mail GitHub site.

The remainder of this section carefully details the Python SDK, it's classes, methods, and properties, along with samples of how to use it for various cases. Other SDK languages are substantially similar.
