Designing APIs is a complex and resource-intensive process. The process is prone to errors, and it™ is extremely difficult and time-consuming to spot and rectify mistakes when modelling APIs. For more information, see https://swagger.io.

Swagger helps developers design APIs using the OpenAPI Specification (OAS). Swagger validates the design in real-time, checks for OAS compliance, and provides dynamic visual feedback. Besides this, you can use Swagger for testing endpoints, requests, authentication and authorization protocols, and so on.
