As per practices of security testing services, API is one of the most powerful testing techniques for code validation, finding bugs and ensuring test accuracy. It is also less time consuming than functional testing. API testing plays a major role in deciding the functionality, security and performance of the application.
Its main role revolves around the backend of the application where it determines the accuracy of requests sent and responses received by the application server. All the errors and responses of the application are handled by APIs itself.
If we take an example of Login page of any application, APIs comes into existence when we provide valid username/Password details on login page, API of that page validates it at the backend and then we moves further by making successful login attempt, however, with invalid/incorrect login API gets fail and throws errors.
