Connecting to the Square API 
This is the project that generates API clients for connecting to the public Square API. You probably want to just use one of the clients that are pre-built in a language of your choice:
The Connect Examples are working sample applications that you can copy from to build your own.
Connect API Specifications
This repository contains the specifications for generating client SDKs with Swagger/OpenAPI.
The canonical specification is defined in api.json. The templates for our
supported SDKs are located in swagger-templates. The configuration for each
SDK (e.g. name of the library, version number, etc.) are located in
swagger-configs.
We use Travis CI to build each SDK and push it out the appropriate repository. To learn more about that process, look in the travis-ci directory.
