Case Study: National Postal Service achieves rapid API delivery and monetizes data with MuleSoft

Reinventing an Industry with the Help of APIs

A state-owned national postal service with a 170-year history (5,000+ employees, $121M revenue) faced a steep decline in traditional mail—over 30% drop in letter volume and reduced delivery days—and needed to reinvent itself before becoming irrelevant. The organization aimed to monetize its demographic data and open services via APIs, but initial in-house and vendor solutions lacked design best practices and backend connectivity, producing inconsistent APIs and long launch delays.

The postal service adopted MuleSoft’s Anypoint Platform for a design-first API approach using RAML, enabling consistent, production-ready designs and easy integration with backend systems. As a result, APIs moved to production in weeks rather than months, the organization centralized API lifecycle management, boosted developer adoption, unlocked new revenue and partnership opportunities, and established a scalable foundation to extend APIs across banking and internal operations.
