Hey @descent-module-ast11

Welcome to the Postman Community! :postman:

> `pm.variables.set`

This scope of variable doesn’t store anything outside of the execution of that request. That’s the reason why you wouldn’t see anything when using `pm.variables.get()` in the second request.

You would need to change the scope to something else (Global/Collection/Environment) that would store the value and make it reusable.

When debugging, ensure that you’re making use of the [Postman Console](https://learning.postman.com/docs/sending-requests/troubleshooting-api-requests/). This will show you exactly what’s the value of something is at any given time.

```auto
console.log(pm.variables.get('createdBy'));

```
