Course Description

API is a very generic term. In this course you will learn what an API actually is and learn how to work with different web APIs:
REST, SOAP and GraphQL.
RESTful APIs (or simply REST API) are everywhere nowadays but at the same time they are getting more complex to get started with: different HTTP methods, headers, cookies, dealing with file uploads or authentication with api keys, tokens, OAuth and so much more.
To work with APIs we will use the Postman app! Postman allows you very quickly 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.
So lets look at what you are going to learn:
Understand what an API really isGet the basics right:
understand the structure of HTTP messagesStart with simple requests and advance towards more complex scenariosLearn to deal with authentication / authorization mechanisms like Basic Auth, API Keys, or OAuth.

Good presentation and explanation. I would recommend this course to anyone who wants to learn API from the bottom to the top. You would never find anything like this course on YouTube or elsewhere for free. I'm very glad that I found this course. Thank you, Valentine!

By Cary Lane Bailey on 10/7/2020

Instructor is explaining everything well, and often, to be sure that the concepts are learned. More opportunities to practice with instructor follow-along would be beneficial.

By Altamiro Moraes Diniz on 10/7/2020

Just a comment in order to improve this excellent training: Valentin could add more exercises along the sections.

By Michal Zajac on 9/22/2020

The instructor has perfect explaining skills. This course helped to clarify some things and prepare me (hopefully) to start playing around with postman. I will also be looking forward to see the Postman course from Valentin.
