The most beautiful thing of this tutorial is, teaching complex things in simple way. Just hold tight for couple of hours with this video, then you are far better equipped with API testing.

[githinjibonface]

This tutorial is great. I love the way the tutor teaches in a slow way.

[madifz]

Not going to lie, learning web dev going into backend felt so intimidating. This course was really fun and knowing how to run API calls with Postman feels like a new superpower.

[AkshayHarith]

I truly enjoyed going through this tutorial! I had some basic knowledge about testing APIs in Postman. But this video just brought a whole new dimension to it.

[ErionCuni]

The best way to explain the main functions of Postman without waisting time.Great Job Valentin!

[beatrizguedes]

I've been looking for a good Postman course for so long and this is the best one! Especially because it also teaches the automation fundamentals, no just Postman features. Thank you so much Valentin! =)

[XTiwnsCooOl]

You are just a life saver, I am just a beginner and this video has helped me in undemanding some of the things I dreaded about APIs. Well done and thanks for your time.

[zekethepumber]

for anyone trying to use newman but are getting errors in your tests, you have to export your global variables from the web interface in postman by clicking "environments" -> "globals" -> "export" and when you run the test via newman in the cli, you have to add the comand line option '-g <source>' at the end

[nehayagnesh]

Valentin, appreciate all your hard work in creating this course. It's really helpful. Thanks a ton!
