Beyond Requests: Postman for Conscious API Developers

In this session, I’ll show how developers can use Postman consciously — as a tool that supports the entire API lifecycle during development and testing.

We’ll walk through practical use cases for variables, environments, and secrets. You’ll see how to write robust test scripts, how pre-request logic can help simulate edge cases, and how to avoid common pitfalls that slow teams down. I’ll also show how to use Newman to run tests in CI pipelines and share some battle-tested patterns I rely on as a tech lead.

If you’ve used Postman before but only scratched the surface — this talk will help you unlock its real potential as part of your daily developer toolkit.
