Case Study: Giant Machines achieves faster, uninterrupted API development with Postman

Postman Collections, scripts, and mock servers keep development fast and fluid

Giant Machines is a 28‑member software design and full‑stack development agency that builds custom web and mobile applications and RESTful APIs. They faced frequent developer downtime and blocked back-end work when third‑party services (for example, a shipping provider) were unstable or wiped test data. To centralize collaboration and reduce interruptions, the team adopted Postman—using Postman Collections, workspaces, environments, scripts, Collection Runner, mock servers, and auto-generated docs to organize and manage API development.

By configuring Postman mock servers for unreliable external services and leveraging collections, environments, and scripts, Giant Machines kept local development moving without altering their codebase. Postman’s tools let them simulate endpoints, run quick environment‑specific tests, and share live documentation, which the team says has saved “countless developer hours,” reduced regressions, sped up testing and handoffs, and streamlined client onboarding and ongoing API management.
