How do I delete a Collection level variable?

[davidgerrard]

My question:
I created a Collection variable by mistake, meant to create at Environment level. Now I can’t delete the Collection variable, and when I try to use the Environment variable it keeps saying it’s “Overridden” by the Collection variable.

Details (like screenshots):

How I found the problem:
I keep getting errors where I’m sending the Collection level value instead of the Environment level value.

I’ve already tried:
Deleting the value at Collection level. Unticking the tickbox at Collection level.

Thank you!

Hey @davidgerrard, Welcome to the community

To simply delete a Collection variable, just click on the x mark on the right.

After deleting, don’t forget to click save.

Hope this helps,
Good luck!

Yes obviously, but where can we find this secret screen?

Hey @sony-andries

Welcome to the Postman Community!

The Collection Level Variable manage section, can be seen when opening the Collection entity in a tab.

This can be opened a number of ways, the easiest being clicking the Collection from the sidebar or using the View more actions menu and selecting Edit.

More about navigating Postman can be found on our Learning Center:

Deleting Collection Level variables can also be handled in the Pre-request or Tests scripts:

pm.collectionVariables.unset('variable_name');

More information about the pm.collectionVariables functions can be found on our Learning Center:
