Developing applications with Swagger documents

The Swagger document that is generated by the z/OS® Connect EE API toolkit can be examined and exposed in various ways.
A range of third-party tools are available for you to use with Swagger documents.
Swagger UI
With Swagger UI, you can visualize and test a REST API that is defined with Swagger from any web browser. The built-in testing functions let you graphically explore the APIs, test the APIs, and inspect the results. For more information, see GitHub: Swagger UI.
Swagger Codegen
With Swagger Codegen, you can generate a Software Development Kit (SDK) in various languages, including Java™, Objective-C, PHP, and Python, from a Swagger document for a REST API. You can use the resulting SDK to test the API in real time with a generated sample server implementation before you fully implement the API. For more information, see GitHub: Swagger Code Generator.

The site, for example, provides Swagger Editor, Swagger UI, and Swagger Codegen.
