Challenge

A booking platform with a large API surface was tested by hand through the UI. API changes broke partner integrations without warning, and nobody knew how the system would hold under peak traffic.

What we did

We automated the API suite with Postman and Newman and ran it on both staging and production. We covered payment and refund flows with Stripe and PayPal, geolocation search and third-party integrations, and load-tested search and booking.

Result

4,000+ automated API tests now run across both environments and 600+ bugs were reported along the way. Breaking API changes are caught before partners see them.
