Envionment/Collection variables Not Sent


#1

Hello,

I’ve created both Environment and Collection variables and added them to the Headers section of a GET request. When I hover my mouse over the variables in Postman, I can see the variable values however when I send the request the values are NULL (in the Postman console).

Is there some trick I need to follow to actually insert them into my GET requests? using version 6.7.3 on Windows 10

How are you calling the variable? For example if you variable is url. You will call it in your get by passing{{url}} in your string.

Yes, I am including the variable and they have values but when I click the Send button nothing is inserted into the request. seems to happen with only one of my collections.

Also, the CURRENT value is NULL but I thought if you set null in the variable setup it would inherit the INITIAL value. Is that not the case? See image:

That’s why.

You’ve set the variable at the environment “initial value” but the “current value” is empty.

You need to set it here when running the tests in Postman application.

Perhaps we should raise a feature request to the Postman team to use the initial value is the current value is empty?

Sorry, I don’t know if I should piggyback on this or start a separate topic, but I’ve never understood why there is this initial/current value distinction. I’ve read the docs at https://learning.getpostman.com/docs/postman/environments_and_globals/variables but couldn’t understand the purpose of this distinction. Is there more information about that somewhere I can read up on?
