Why API Testing is required?

Application Programming Interface, or API, is an interface that facilitates communication between two software systems. It is possible to link certain functionality or business operations with front-end code to abstract the written business logic and programming complexity, and this is known as a function. The separation of business logic from other application resources and cross-platform compatibility would both be greatly aided by API.

Examining API
To significantly limit the amount of flaws that might be discovered during functional testing of the program, we need to test the application's fundamental business logic.

The purpose of API testing is to validate the API's functioning and make sure it satisfies the functional requirements. Since APIs are used to communicate between various software systems, integration testing depends on it. API testing assists in finding problems early in the development process and helps avoid expensive bugs and mistakes in production.
