Focus On Small Functional APIs

In most testing projects you can easily find APIs that are small and simple and have one or two functionalities. For example, they have functionalities like getting tokens, user authentication, health check, etc. But despite being so small and simple they play a very important role in an application and act as a gate to enter other APIs. Thus it is very important that you focus on them and test them first to make sure that the environment, server, and server authentication are working properly. Besides this, you should not test multiple APIs in a test case. Why? Because if an error occurs while testing them then you will have to check the entire data flow generated by them to rectify the error. Scary, right? So make sure you keep your testing simple and test only one API at a time.
