Case Study: Telus modernizes API governance and accelerates development with Stoplight

Telecom giant transforms a legacy system with a Design-First workflow fueling development and innovation

Telus, a Canadian telecommunications company, faced challenges with an aging and inflexible SOAP-based API platform that was difficult to scale and update. The legacy system resulted in inconsistent API designs and non-centralized documentation, creating a barrier to rapid development and innovation. To address this, Telus partnered with Stoplight to modernize its API design and governance workflow.

Stoplight's solution provided the tools for a new design-first workflow, including its visual design editor and Spectral linting for automated governance. This enabled Telus to implement a systematic "front door" process for API development, ensuring consistency and reusability. The results were significant, with over 1,000 employees adopting the platform. Stoplight became the source of truth for API design, streamlining reviews and accelerating the delivery of modern, high-quality REST APIs.
