Whether you are a developer or have little development knowledge, you will be able to understand it thanks to Swagger UI.Įven machines can read it, turning it into another very attractive advantage. The most important of them is that everyone, or almost everyone, understands Swagger. Swagger helps us create documentation that everyone can understand. In this manner, we can create documentation that is actually useful for people who need it. When speaking of Swagger we are referring to a set of rules, specifications, and tools that help us document our APIs. Postman is appropriate for testing such API based on specifications. Swagger is an API specification & Postman is an API Client and appropriate for API first development while,

In this blog, we will explore a few of the most commonly used tools in REST API testing and how to use some of their most important features, in addition to determining which one suits a development process the best.
