Case Study: Belong.co achieves 50% reduction in testing time and streamlined API collaboration with Postman

Belong keeps its architecture in order with Postman

Belong.co, one of India’s fastest-growing hiring platforms, shifted from a monolithic system to a 25-microservice API architecture with 70 engineers relying on APIs for core functionality. Managing that many APIs with ad hoc tools left teams spending roughly 30% of their time on testing and struggling with communication whenever endpoints changed, creating wasted developer hours and onboarding friction.

Postman solved this by moving Belong.co to Postman Cloud, using Postman Collections as the single source of truth, and defining tests inside Postman to validate API schemas. The move eliminated documentation drift and communication overhead, gave instant API updates to teams, sped up onboarding, and cut time spent on testing by 50%, freeing developers to focus on mission-critical work.
