Postman

Postman is a collaborative platform for the development and testing of APIs. This tool simplifies the steps involved in building an API so that one can create robust APIs in a relatively small amount of time.

Let’s have a look at a few services that Postman offers:

Manual tests can be automated and integrated into the continuous integration pipeline to make sure that any modifications to the code will not break the current API.
REST and SOAP API requests can be sent quickly and easily for testing, or for other purposes, within Postman.
The behavior and response of an API can be simulated across endpoints without having to build the actual backend server.
Clear and simple documentation can be produced to make the APIs more understandable.
One can evaluate the performance of created APIs by monitoring response times between intervals.
