Pre request scripts for all requests in collection and workspace

[jakob-lj]

Thank you for an excellent tool!

We're utilizing the pre-request script feature in our Postman collection to run the same script for all requests within the collection.

Since many of our requests share the same authentication mechanism, it’s essential to refresh tokens as needed without duplicating code in each request. By applying the DRY principle, we've streamlined this process in Postman. The pre-request script updates variables, which are then used for authentication across the collection.

The requests inherit the authentication and variables from the collection, making the implementation both efficient and maintainable.
