API stands for Application Programming Interface which helps two independent software to communicate with each other.
When an application is built, the functionalities are built first as APIs and then integrated with the frontend layer (UI).
Waiting for integration to find bugs in the application will add a lot of costs. The later the bugs are found in the system, the more cost it adds to the application.
API Testing helps reduce the cost as it will be performed before integration with frontend (or UI).
JMeter is famous for performance testing but is equally good for API testing as well.
In this one-hour guided project through hands-on, practical exercises, you will learn the basics of API Testing using JMeter tool. Sending GET, POST, PUT, and DELETE request and understanding JSON request/response format.
