APIs make it possible for any two separate applications to transfer and share data between them. They also make it easier for an application's users to execute actions without having to use the application’s GUI. From the developers' POV, it's an easy way to execute certain functionalities of their app and test it as well.Using APIs on a daily basis might become cumbersome, as one might have dozens or even hundreds of APIs that he or she needs to use or test. That makes it difficult to keep up with their exact request’s address(es), header(s), authorization credential(s) etc. And it makes it harder to test the API for functionality, security, and exception handling.Table of Contents:What is Postman?Why Use Postman for API Testing?How to Use Postman to Test APIHow to Create Postman Collections for Sharing BlazeMeter’s APIRunning a Postman Collection Using Collection Runner Using APIs Within Your Own App or Script With PostmanWhat is Postman?Postman is an API client that makes it easy for developers to create, share, test and document APIs.
