You are not the first one. REST APIs are everywhere nowadays but you may not know where to begin. If you are a total beginner to APIs and are looking for a quick introduction to API by using Postman. This course is for you.

What are APIs all about?

However, learning about APIs can easily get confusing. You need to know: different HTTP methods, headers, cookies, dealing with file uploads or authentication with API keys, tokens, OAuth and so much more.

This is where Postman comes in! Postman allows you very quickly to create a request with the required HTTP method and parameters, submit the request and easily inspect the results.

Postman can help if you are developing APIs as well! I have created this course for testing engineers and well as for software developers.

Postman can help you during the development of your API as well as after the API is completed, by running tests that make sure your API is still working as intended.

In this Postman crash course for beginners, we will start exploring the features of Postman, creating requests, and building simple workflows. Then we will continue by writing API tests and automatically running a Postman collection
