Description

Do you need to learn about Postman & APIs for your new position or for a job interview? 

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?

Today, all IT systems are interconnected by using APIs, which are a way to exchange data, mostly by using a format call JSON.

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 by using the Postman Collection Runner and Newman.

Is this course for me?

If you need to get up to speed with Postman and start using APIs and don't have a lot of time, this course will probably take you very far in a very short time. You don't need much to get started, but you need to invest more than 3 hours. Just watching the content may not be enough to develop the skills needed. You need to do the work and the practice assignments.

So let’s look at what you are going to learn:

  • Start with simple requests
  • Use HTTP methods like GET, POST, PUT & DELETE
  • Understand the difference between GET vs POST.
  • Work with query parameters and path variables
  • Understand HTTP headers
  • Learn to deal with authentication (for example using Bearer token)
  • Start writing API tests with JavaScript
  • Organize tests in collections and share them with your team
  • Run API tests using the collection runner or Newman

So after this course, you will have an overview of Postman and can later decide in which areas you want to learn more.
