Having good API documentation is one thing. Being specification-first is next level. My latest post on the Bump.sh blog looks into the benefits a specification-driven, git-based approach to documentation can bring to partner API integrations.
The idea is that by using a source of truth and focusing on documentation earlier in the pipeline, API providers can produce more accurate, detailed descriptions and evolve their service more effectively. This can benefit discovery and resolve drift, equating to a better partner experience.
If you're an API provider opening your API to partners, definitely check out this one for some solid reasons why spec-driven documentation should be at the forefront.
