First thing, " Change it to the black theme" . This is our hero!
Felt the same emotion lol :P
I paused and immediately liked the video when he said that.
For sure, with normal theme, you can't see anything. Does not matter wich OS.
As a QA automation engineer, I purposely keep it in light theme, since developers keep it dark. Archenemies:)
😂😂
Sometimes I can not believe that there are people who spend days to make such great educational videos are generous enough to host them for free on TH-cam.
Thank you so much for all the work you did to make this video
I am glad you appreciate the effort behind educational videos. Thanks for watching.
@@vdespa Lots of thanks indeed. I usually can not believe too, as Hugo beautifully noted.
Yes! Thank you! I am learning so much!
he does it for money bro
I've always thought the same thing. Especially people with small accounts making $0 from it, teaching you to fix your car or something with no intention of making money off youtube, just trying to help people
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 ' at the end
Valentin, appreciate all your hard work in creating this course. It's really helpful. Thanks a ton!
This is literally everything I needed. I've spent a week trying to find any good course in online platforms and now I'm watching the best one for free.
Great to hear that, Kristine!
really?
This is such an incredible video that covers the fundamentals of API testing through Postman. Your pacing, amount of detail per each segment, and practice assignments were all spot-on. Looking forward to watching more of your content and truly appreciate the hard work to help others grow.
Thank you for your kind words, Chris!
Thank you, this covers a lot of things but the way you split it out makes it more manageable
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.
Explained in the most simple manner. Went through everything step by step and in a very structured format.
This tutorial is great. I love the way the tutor teaches in a slow way.
This was the best educational video that I have ever watched in TH-cam - so nicely and fully explained with examples and tasks, with no rush and calm tone all the time. Thank you very, very much for the efforts to share your knowledge with us!
Awesome training! Really well structured and paced - thanks man!
Excellent Beginners course Valentin. This has helped me gained more knowledge on features I was not aware of and helped solidify the existing knowledge I did have. You presented this in a way that was logical and easy to understand. I will be looking for more of your videos.
Thank you very much for your course. Everything is very well thought out, neat and interesting. Very good balance between theory and practice, the need to write documentation has never been so convincing. Good luck and good code!
An outstanding course !!!
A must-watch for anyone starting with postman.
It's clear, concise and has very bright assignments to practice and check your understanding.
A big "BRAVO" and many, many thanks to Valentin.
Thank you for your kind words, Fred! I'm glad that the course was able to provide you with the knowledge and skills you needed to get started with Postman. If you have any further questions or need additional guidance, please don't hesitate to ask.
A big THX and applause to You Valentin👏. This was an amazing tutorial experience : Clear structured, pointing to the highlights, very valuable handling tips to avoid errors...
I just got a new job task involving postman and then you drop this!!!!! I already love you guys, give me a breather here.
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! =)
You're welcome, enjoy! 🚀
oh no
I'n only 1/3 of the course but I already fell in love with the way he articulately presents the steps. Not many people can teach but this dud does.
You're born with this teaching skill.
Thank you!
Thank you, you are too kind.
Hi Valentin, Saurav
, Pradeep. The course is just awesome! The structure is clean and the content is divided into the right size "portions" that are simple to follow. The assignments are really helpful. The presenter talks not too fast and not too slow and with no "extra" words that make the "student" to understand the presented content almost effortless. Thank you !!! 🙌
Thanks, AT!
As a automation engineer i was finding tutorial like this and finally I got this one.
Your explanation is more than awesome.
More power to you and this channel 🙏🏻💯
OK. Let's state it: this presentation was a masterpiece. Both simple and yet precise and full of explained functionnalities. Great job, Valentin, and thank you. It really does help!
Great to hear that, thanks!
This has been a very informative and well presented tutorial. Well done, Valentin. Keep it up!
Everything about this tutorial makes so much meaning each time I come back to watch. I'm still on my job, thanks to you.
Mar 2021: I dabbled with Postman a few years ago with no guidance, so this video certainly sets a good direction for further learning. Thank You!
This video helped me a lot to understand the postman once and for all, the course information is well structured.
Thank you, thank you, thank you! I can't say it enough. This is super helpful and I love the way you have laid the sessions out. Happy viewer and learner here.
Thank you very much Valentin! The details, explanation and assignments were great. I felt overwhelmed at work by not having experience testing APIs, I watched this today and now I'm testing our team's APIs (way more complex but the bases you explained are there). Let's goooo!
Happy to hear that, thanks for your nice comment.
You literally answered all of my questions in this one video. I am now able to leverage the Qualtrics API to do some pretty amazing things. Valentin, much appreciated!
Great to hear, Joshua! Thanks for your comment.
After looking though so many other videos, this one seriously was so clear, concise and to the point. I appreciate the effort, I was able to learn so much
I am glad you found what you were looking for.
Amazing tutorial! 1st time Postman user, with the only knowledge of JS being variables and functions, and managed to understand it perfectly fine. Honestly, this should be no. 1 in the Postman tutorials globally. Seriously! Simply perfect, straight forward, no BS, intro Postman for beginners.
P.S. They reintroduced the "Run collection" option in the collection Drop menu in v. 10.17.2
I love Postman. I’ve used it with the Microsoft Teams API. It was so intuitive that I managed to understand queries, variables, body and parameters without any training or documentation. I just knew how APIs work, and that was enough.
You can even get the code for fetching that data in many different programming languages like PHP, Bash with curl or Perl. That saved me a lot of time.
I did not want to leave any comments as I was being lazy. Then I thought about how much I learnt from this tutorial and the effort you put in, for free. Thank you so much.
I love your style Valentin. Your video tutorial is clear and transparent. Thank you for sharing your hard work with us. Much appreciated.
I am glad it was useful, thanks Daniela!
One of the best educational videos explaining details at a steady pace. Kudos.
Really good tutorial. Explanations are not too deep but enough to get the hang of the feature & how one can explore more. Thanks a lot :)
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.
Glad to hear that, thanks for your comment!
One of the best tutorials I've ever seen, hands down. Well done!
Thanks a lot!
Just paused the video midway and came to comment here...clearly shows how much I appreciated the content ...Kudos to the instructor..Good Job!!
I was looking for a course for so long. Thank you for this. Great job!
It's just an incredible video, couldn't be more perfect and effective, and I love the instruction of your voice..for sure adding to my list. Thank you so much!
Thank you for your kind words, Nadia!
Just completed the whole course and definitely it is a best course for beginners for learning postman. Thanks Valentin and please keep uploading these type courses these are very helpful and the best part is the way of explanation. Thanks again.
Thanks for going through the entire course.
What an amazing tutorial. Just perfect in terms of content, pace and details. Just every thing i needed to know. Thank you so much for this.
You're welcome, Shubhi!
The best way to explain the main functions of Postman without waisting time.Great Job Valentin!
Thanks, Erion!
Just finished the full video with hands on practice. Can't thank you enough. Thank you so much for this great video. Wish you best of luck, valentine.
You're welcome! I'm glad to hear that you found the course to be helpful and that you were able to put the concepts into practice. It's always rewarding to see students applying what they have learned and achieving success.
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.
So true. Thanks for your comment.
I really can't thank you enough for this instructive, educational and straight to the point video ! Thank you so much !
Brilliant intro to Postman. Really enjoyed it. Thank you so much!
Amazing content 🙌🏻👏🏻👏🏻😊 so neatly explained without any show off and graphics and different sharp high and low tones. You are so damn good at it more power to you😇
This was really a very good getting started with postman and gives enough opportunity to learn for most common use cases. thank you so much
You're welcome!
Just learning APIs, really appreciate you covering a variety of calls. Very helpful, thanks.
After looking all over I finally found a video that I can follow without getting unknown errors. Thank you for such great video!
This is one of the best self study videos I've seen.I stopped numerous times to mess around myself. If you want to you can learn the basic and a bit more in 2-3 days with help from this video. This gives you a good solid foundation. Huge thumb up ! Easy to understand, very modular like Lego bricks.
Thanks, Jesper - much appreciated!
What a nice coincidence while I'm doing my API 🤣
A BIG THANK YOU!
almost same here, studying HTTP and API basics today
same here, just had a call with my manager to do the same, here i got this recommendation
Universe works in mysterious ways
Loved this course. As people before me have said - well paced, well explained and to the point. Thank you!
This looks amazing. Bookmarked !!!
Thanks it will be very helpful for people starting with postman. It's such an useful tool
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.
Thanks for your comment! Glad you like my teaching style.
Crazy video Valentin. Really well explained and great examples! Thanks for the lesson :)
This is pure gold, thank you for the great tutorial
You bet, Jasur!
Absolutely fantastic training. I got my API testing set up and running in one afternoon. Thank you for all your efforts and for sharing this information.
You're welcome!
Thank you for all the effort you have taken in creating this course for us. Great job.
You're welcome, Ram!
I’ve bought this guy’s postman course at udemy. This video is really useful! I strongly recommend
Can u plz give the udemy course link 😊
So I paid around $20 for a highly rated Udemy course, and I feel robbed after watching this video. So clear and concise, great job on what I can only describe as a great tutorial for Postman!
This author has a good course also on Udemy
This is one of the best tutorial videos I’ve seen in TH-cam, thank you so much 🙏
Great, thanks a lot!
ely the best tutorial I've seen on TH-cam. I'm subscribing to this channel because of the clarity presented by the teacher.
You're welcome! Consider subscribing to my channel as well :P
I LOVE YOUR TUTORIAL it's very easy to follow and understand! Thank you so much
Thank you. Check my channel for more Postman-related content!
My God, this is what I have been looking for since last year! Thank you!
"Collection" now is called "Folder"
I am following the course, and it also allows you to save the API code in the main folder,
thanks for the video btw, finally I can listen to some tech stuff in not-Indian accent :D
(don't misinterpret me, I have no problem with Indians, I like them, just listening to tech stuff in their accent is painful)
Wow! I've been using Postman for years but didn't know it's capable of automation. Thanks a lot
Thanks I was lokking for it for a long time it means a lot

Excellent introductory course for API testing using postman. loved the way you have explained. Thanks.
Thanks, Amit!
The fact that he changes his theme before anything else, is just wonderful.
great video and nice voice - thanks from Vietnam
Thanks will look after 5 months.
Valentin, you're my hero :-) Some 2 weeks after I took this first course, I watched another video of yours and voila, I found the solution to a problem I was struggling with, fast and simple.
Excellent explanation and hands on course for anyone to learn the API thru Postman! Good job
Thanks.
good job.
hey -- I did the UNIT 1 , in which we manually test the API's . Loved your way of teaching. Thanks a ton !!
Hey Janet, keep going! I am sure you will learn more useful things.
Thank you so much for this videotutorial about Postman! I always wanted know how to work with this tool, and finally I found this video and I'm very grateful :D
Hugs from Argentina/Perú (South America).
What a good man
are u sure it's a man ??! looks like a woman more than a man...
Great course! I also prefer dark theme most of the time, but for the purpose of making an educational video, light one would have been more clear.
Amazing tutorial. Thank you so much for the great effords you have spent.
Thanks for watching, Deyan! I am glad it was useful!
Thank you so much for uploading this on TH-cam for free. Valentin rocks!
Thank you for this awesome course! I just have a question. When we take a token and copy it for authorization, I forgot to copy it and sent another request to {{baseUrl}}/api-clients/. But this time as in the video, I recieve "error": "API client already registered." I waited for a couple of hours but I still get the same error. Does anyone know how I can solve this?
Hi there, try to change the email address
I used one of my person emails and it worked.
@@semiserioussam thank you!!!! appreciate it
Hi! Useful video, thank you. Just want to ask: is anyone receiving an error when trying to order a book? Up to that point, the responses were the ones you got. But I get "Invalid or missing bookId", even though I get the list of books and their id's are ok.
L.E.: Yep, found my mistake. I forgot to select JSON. Issue solved. I will leave the comment in case someone else needs it :)
Thanks for posting, Rox. Glad you have solved it on your own.
The moment when you told switch to black theme. I knew I came at the right place. So clearly explained in the simplest possible manner. Thanks a lot.
Thanks, Rohit.
Super thrilled to learn more about Postman after watching this Video. Thanks to Valentin Despa!!
first thing I like to do " change to black theme"
this should be important for every tutorial lol
I actually prefer white background theme.
make sure you don't skip the first step in this tutorial of turing your dark mode on or else nothing will work
