Case Study: Large Global Retailer achieves 40% faster API testing and higher-quality releases with Sauce Labs API Testing & Monitoring

Global Retailer Switches to Sauce Labs API Testing and Functional Monitoring for CI/CD Pipeline and Microservices

A large global retailer migrating from a monolithic architecture to microservices and adopting CI/CD relied heavily on internal APIs for e-commerce, stores and logistics. Their existing API management platform couldn’t deliver usable feedback, lacked end-to-end observability, and siloed testing expertise—making it hard to diagnose backend issues, reduce false negatives, and scale API testing across distributed teams.

The retailer switched to Sauce Labs API Testing and Monitoring (formerly API Fortress) to standardize API testing across toolchains and enable end-to-end, data-driven, and mocked testing integrated into CI/CD. The platform’s richer reporting, test reuse/correlation, OAuth automation, and load-testing capabilities cut testing time by over 40% without adding headcount, reduced false negatives, accelerated bug diagnosis and remediation, and increased developer velocity and consistent quality-at-speed.
