Introduction to API

What is an API?

API(Application Programming Interface) serves as a middleware that enables channeling data between software products. It can be used to define requests made, handles business logic, the data formats that should be used and the conventions to adhere to when building software products, etc.

Testing Tools



A free, fast, and beautiful API request builder with an online testing environment, support for multiple platforms and multiple devices, and many more.



This tool simplifies testing API endpoints in Java, it tests and validates responses.



Paw is a full-featured HTTP client that lets you test and describe the APIs you build or consume. It has a beautiful native macOS interface to compose requests, inspect server responses, generate client code, and export API definitions.

API Documentation

API Documentation is one of the most important things to note after developing and testing your APIS, it simplifies the process of understanding what each endpoint does or their request samples and responses. Imagine you build several endpoints for user authentication, you aren't available but one of the frontend developers on your team wants to consume it and there is no guide or instructions to what each APIs does or sample request and response, that's a flaw that can really slow down the development process.

here are some tools you can use for APIs documentation
