The industry standard for designing, consuming, and sharing rest APIs with ease
Swagger offers the most comprehensive tools to help you take full advantage of all the capabilities of the OpenAPI Specification (OAS).
The OpenAPI Specification (OAS) creates a common framework for the entire API lifecycle to define your RESTful service’s functionality, including their resources, and associated request-response cycles. The OAS is both human and machine readable, and acts as the blueprint of your entire API development and delivery letting you communicate the value and functionality of your API, both to internal stakeholders, and external consumers
Another advantage of using this approach is the improvement of Developer experience. Developer experience is about delivering robust functionality that is stable, speedy, and visually intuitive.[2] If you’re thinking about how it can improve the developer experience, you just need to remember that developers will consume your API and having a well defined/documented API will have a great impact on it. You can focus on the API consumer’s needs beforehand.
