Excellent overview of Postman variable types and scopes. Truly appreciate the relevant examples used. This is perfect to help educate my users on the right way to manage secrets. Thanks!

Thank you for a clear explanation. I've expanded my instruments now with "values".

Running with a data file was game changer, thank you!
