Start with the document they actually need
External collaborators rarely need the same view as the engineering team. Decide which endpoints, schemas, environments, and examples belong in the handoff before choosing a hosting tool. This keeps the shared document useful without turning it into a copy of your internal API catalog.
- Create a partner-facing spec when the public contract differs from the internal one
- Include enough examples to complete the integration
- Leave out internal endpoints, incident notes, and experimental operations
- Use separate pages when clients receive different contract versions
