I was using Postman in my previous company for basic use. Now after I gone through this video, I came to know about the nuances of the Postman and its entire usage. I'm confident now that I can showcase my skills and knowledge moving forward in Postman.

Thank you! #KeepTeaching #KeepLearning

Hi Raghav, Please post videos on Tableau, ETL Testing, Accessibility Testing (JAWS) and Penetration testing (Burpsuite)

[hectormanuelmh]

hi Raghav, I was following this great course but when I try to run the collection I got this error, I was looking for a fix on internot but not lucky so far, have you any idea what can I do to fix this? thanks in advance: Failed running the collection: TypeError: Cannot read properties of undefined (reading 'id')

[slobodanparizoski]

Is it possible to have different envs for the same collection? And to be able to use variables from them in one collection run? This is needed to group the variables in an understandable manner and for easier maintenance.

[shubhs]

Please tell how to check json response is normal or dynamic.
