What is swagger api?
Swagger is a specification for documenting REST API. It specifies the format (URL, method, and representation) to describe REST web services. It provides also tools to generate/compute the documentation from application code.
The goal of Swagger is to define a standard, language-agnostic interface to REST APIs which allows both humans and computers to discover and understand the capabilities of the service without access to source code, documentation, or through network traffic inspection. When properly defined via Swagger, a consumer can understand and interact with the remote service with a minimal amount of implementation logic. Similar to what interfaces have done for lower-level programming, Swagger removes the guesswork in calling the service.
