Persist environment variable automatically after updating it's value

Hello all!

I have an environment variable as a mock response and every time I update the environment variable value, I need to persist it to be able to reflect it as a response form the mock server.

Is there some way I can automate this (persist process) so that I can run all my requests at a time in the collection runner.

Thanks in advance for your replies!

Hi bbahadur,

Welcome to postman community :slight_smile: .
I believe what you are looking for is to set the environment variable automatically rather than manually?

If that is the case you can use


Let me know if this helps.


Hey @skandh-15 ,

Thanks for your response,
I am able to set the environment variable value, what I want to do is to persist the variable value, i.e. have both ‘initial’ and ‘current’ value updated. And I want to do this via code/script, rather than clicking on the ‘persist all’ button. I hope I made the scenario more clear.


I somehow missed this in the help center. The problem is now solved.
Sending the PUT request with the details of the same environment every time I update the Environment variable’s value. Working well.
