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

@AudunWangen 3 года назад

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.

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 !!! 🙌

@zekethep1umber Месяц назад

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

@madifz 2 года назад

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.
