Postman is very helpful to create API collections. We can easily share with other people. Postman is used for documentation. Mail by it helps to rectify performance errors and allows automated scripts for testers.so, I prefer to use postman.

It is extremely easy to understand, teach and use for API testing and development.It's also very easy to use for trouble shooting and debugging.

I do all my API testing with postman once I finished developing them. I use the desktop free version and even though it has limited features, they are enough for me to proceed with developer testing. I create collections and can create requests inside. I can keep everything in clean in organized manner. Once I completed the developer testing I share or export and send the same collection to the QA engineer.

It's very simple to start working with Postman, creating new requests, organizing them in folders, and even linking them together by properties.

The code generation feature is very useful.
