API governance extends beyond creating and implementing standards with tools, emphasizing the critical role of people in the process. At Redocly, API councils, composed of cross-disciplinary experts, play a pivotal role in advising, reviewing, and overseeing API development, particularly thriving in a design-first approach where early input is crucial. These councils use the OpenAPI description as the definitive source for proposed changes, allowing for precise discussions and minimizing uncertainty. The council's diverse composition ensures that design decisions are well-rounded, integrating perspectives from developers, product specialists, and technical writers, who act as "customer zero" to foresee user challenges. The council process may follow a regular meeting structure or an asynchronous review style, both fostering comprehensive feedback and clear documentation while avoiding becoming a bottleneck. Long-term, dynamic involvement in the council is vital for sharing knowledge and maintaining a robust API ecosystem.
