It allows you to use variables so that the same request works, whether it’s in the testing or staging environment. In these courses, you’ll learn how Postman can help simplify working with an API.
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. As a developer, it's 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. 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 2, and so much more. RESTful APIs are everywhere in the modern web world. Before exploring Postman, let’s talk about REST APIs which have completely changed how the frontend should interact with backend systems. In this article, I am going to share some of the best online courses and tutorials to learn Postman for API testing and development. If you agree with me that Postman is definitely worth learning for frontend and backend developers and looking for some excellent resources to master this awesome tool, then you have come to the right place. It is also one of the vital tools for Web Developers, and I have already included Postman in my list of 10 Things Every Web Developer should learn in 2022. 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. There is no doubt that Postman is one of the most popular and essential tools for REST API development and testing, particularly for front-end web developers.
