Postman is a great tool when trying to dissect RESTful APIs made by others or test ones you have made yourself. It offers a sleek user interface with which to make HTML requests, without the hassle of writing a bunch of code just to test an API's functionality. .
In Postman, you can make requests to APIs you are working with and examine the responses without using a terminal or writing any code. An API request allows you to retrieve data from a source, send data, delete data or update it. When you send a request, Postman will display the API response it receives from the API server in its user interface. That way, you can examine, visualize, and, if necessary, troubleshoot it.
