Best Way to Handle Authentication Across Multiple Environments in Collections

Help Hub
1

Hi everyone!

I’ve been working with Postman to manage several API environments for a project, and I’m looking for some advice on the best way to handle authentication tokens across multiple environments and collections. I’ve seen a few related topics in the Help Hub, but I’m still unsure about the most efficient and secure approach.

Here’s my situation:

  • I have separate environments for development, staging, and production.

  • Each environment issues a different auth token after login.

  • I need my requests in collections to automatically pick up the correct token without manually copying it every time.

Right now I’m using:

  • Environment variables to store the token

  • A pre‑request script to refresh the token if it’s expired

This works, but feels a bit clunky as my team grows and new contributors start using the same collections. I’ve also seen people mention using global variables or Postman CLI automation, but I’m not sure which option is best for team workflows and automation runs (like in CI).

Questions:

  1. What’s the recommended pattern for storing and refreshing auth tokens across multiple environments?

  2. Do others prefer pre‑request scripts, Postman environments, or something tied to the Postman CLI?

  3. Any tips for keeping tokens secure while still making it easy for teammates to run tests?

Would love to hear how others are handling these challenges — especially in larger team or CI/CD setups.

Thanks in advance!
