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.
But before you start investing 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 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.
In the first part of the course we will start exploring the features of Postman and continue by writing API tests with the intention of integrating them in a CI server where the tests will run on a current basis.
But this is not the normal course you take part in. Because your needs may be different and because I hate leaving you wondering what to do next, the second part of the course will include user questions and answers to problems that were not yet covered in the course or that are more specific and may not interest everybody.
So let’s look at what you are going to learn:
-
Start with simple requests and advance towards more complex scenarios
-
Learn to deal with authentication / authorization mechanisms like Basic Auth, API Keys, or OAuth.
-
Start writing API tests
-
Organize tests in collections and share them with your team
-
Run API tests in Jenkins or any other CI server
-
You ask, I answer
So after this course you will know how to use Postman as a pro.

Course is very nicely design. Now I want to explore more about postman and want to do work in manual as well as automation testing in potman….Thank you valentine to give such nice expaination and presentation of this course.
Juanita Cuan fong –
Great learning experience, a lot of resources shared with us and Valentin always tried to help us to solve our doubt. Thanks a lot for that.
José Alejandro Perales Luna –
It is a good course, explaining major functions of postman, newman. I would suggest to dip more into complex things. For example, go thorugh a real API Testing project from start to end.
Jake Stolarsky –
You have a very nice idea with sections checking knowledge, it forced me to practice the acquired knowledge and not just passively watch the course.
Helen Turner –
This is a great course and I have learnt alot. Thanks.
Leonard Joubert –
I think this is a good course to learn Postman, and an EXCELLENT course to learn tests automation principles, very good learnings.
Siji Falore –
Nothing sounds as depressing as most of these so called tech instructors. I mean sounds so dry. A lot of free youtube videos on the subject are more useful.
Abdul Qadir –
Great course, very practical and applicable. Thank you Valentin!
Quynh Nguyen –
I have been using Postman for a few years. But I have never figured out how great the tool is. There are a lot of interesting things including path variables, scope variables, testing, newman, mock servers,… in this course that I’ve never known. Choosing this course is absolutely my right choice. Thanks Valentin for creating wonderful courses!

Hi Valentine,
Today I completed the ” Postman : The Complete Guide – REST API Testing” course. Must say that this course is brilliant and anyone who wants to learn POSTMAN tool for REST API testing should definitely buy this course.
What I like the most about the author is that he is so composed, so calm and also has the ability of making complex things so simple. This is a very detailed course and the author has explained with such clarity and attention to detail.
Also, there is a Javascript section that can help you refresh your JS concepts.
Overall this is a fantabulous course !!
Thank you so much Valentine for sharing your knowledge !! You are a great instructor and I have a hands-on of all sections you have taught !!
This was a great buy and value for money !!
Thanks,
Janet Dsouza

no words of/Course best course out there

Velentin Despa has a boring, tired presentation. This course isn’t easy to get through. It’s not an exciting subject to begin with, and the instructor doesn’t do anything to make it better. That said, this is a course that I am comfortable recommending to others. Simply because being comfortable with Postman, and more importantly API testing, is a vital skill that you won’t find a lot of quality courses for. This course is so detailed that it’s referenced in the Postman documentation. It goes over every feature you can think of. Variables, Chai assertions, mock servers, automating tests, and so on.
That being said, this is basically a run down of the Postman documentation. I would argue that doing this course is better than spending a weekend going through every point in those docs, but regardless, the course could be better. For example, by using a large project that can be cloned from GitHub and testing a variety of endpoints, and using that project through the entire duration of the course. Instead it uses some example API’s to build on, but those never fully flesh out. Instead of one project that builds on the knowledge gained as you go, you hop between small examples for different categories. Not to beat a dead horse, but this is the structure of following documentation word for word. So you never get a full picture of everything you’ve learned. The instructor doesn’t seem to have put as much effort into creating a coherent, smooth structure as I’ve seen in some of the best courses. The best courses I’ve taken practically create a classic hero’s journey. But that doesn’t happen here.
I can’t complain on that point too much. Even if I consider it to be a major issue. This course is a worthwhile investment. And probably the best course on Postman out there. Valentin Despa is competent, and keeps things up to date without too many thrown in patch videos that feel out of place. Postman is a foundational skill just about every developer needs today. And this course will take your knowledge beyond most professional devs. A junior developer could take the lessons from this course and bring a lot of value to a company that doesn’t realize how useful Postman is. (And this is most companies.)
Despite poor delivery and a follow the docs structure, this is a competent course on a good subject.
