Build Faster, break less: From API design to delivery with Postman V12

In this live demo, we’ll walk through how to build faster and break less by connecting the entire API lifecycle - from design to delivery - using Postman V12.

We’ll start at the design phase, applying governance rules early to enforce standards and catch issues before they reach production. From there, we’ll adopt a Git-native workflow where API specifications live alongside code, enabling better collaboration and version control.

Next, we’ll generate tests, automate validation in CI/CD pipelines, and explore how AI can accelerate tasks like test creation and documentation. Finally, we’ll surface results in a centralized API catalog, improving discoverability, visibility, and confidence across teams.

By the end of this session, you’ll see how to unify design, testing, automation, and governance into a single workflow - helping platform teams deliver APIs as reliable, scalable, and well-governed products.
