There is no doubt that Postman is one of the most popular and essential tools for API development and testing, particularly for front-end web developers. It is used by over 3 million developers across the world, which is a good indication of the fact that Postman is an essential tool for REST API development and API Testing.

In this article, I am going to share some of the best online courses and tutorials to learn Postman for API testing and development.

Before exploring Postman, let's talk about REST APIs which has completely changed how frontend should interact with backend systems. RESTful APIs are everywhere in the modern web world. Still, at the same time, they are also getting more and more complex like different HTTP methods, headers, cookies, dealing with file uploads or authentication with API keys, tokens, OAuth, and so much more.

As a developer, its not easy to work with a new API and it also makes a lot of sense that before start investing your time writing code to retrieve the data the API is offering, why not test the request first to make sure everything is working as expected?  This is where the Postman App comes in! Postman allows you to quickly create a request with the required HTTP method and parameters, submit the request, and promptly inspect the results.

When working with an API, there's always so much to remember, such as any special API keys, different URLs for different environments, as well as the shape that each request should take. In Postman Fundamentals, you'll learn how Postman can help simplify working with an API.

It allows you to use variables so that the same request works, whether it's in the testing or staging environment. You'll also learn how you can create automated API tests so that you ensure your API doesn't break between releases.

You'll even see how Postman simplifies writing documentation for your API so that your users can have an up-to-date explanation of what your API is doing. By the end of this course, you'll know the ins and outs of Postman, and be equipped to maximize your interactions with APIs.
