RESTful APIs (or simply REST API) are everywhere nowadays but at the same time they are getting more complex to get started with: different HTTP methods, headers, cookies, dealing with file uploads or authentication with api keys, tokens, OAuth and so much more. Postman allows you very quickly create a request with the required HTTP method and parameters, submit the request and easily inspect the results. The Open API Specification (often called "Swagger") is currently the most popular way to create definitions of RESTful APIs. With these definitions, you can create sophisticated, auto generated documentation, generate SDKs in several languages, and do automated testing. Swagger is a set of open source tools that use these Open API Specification definition files
