Standing up an API Catalog is mostly tool configuration. The harder work is the publication discipline and governance that keep the catalog useful over time.
- Decide the catalog scope
Internal-only, partner-facing, or both. Public catalogs need stricter content review and a polished discovery UI; internal catalogs can be more utilitarian.
- Configure Anypoint Exchange and API Manager
Enable Anypoint Exchange as the asset store and API Manager as the run-time governance layer. The two together feed the API Catalog.
- Onboard the first three high-value APIs
Pick three APIs the org already runs heavily. Publish their specs, owners, SLA, and consumer docs to the catalog. Confirm the search and discovery UX works against real content.
- Define governance and lifecycle rules
Document who can publish, what review the spec must pass, how versions are numbered, and how deprecation is announced. Without rules, the catalog accumulates noise.
- Expand to the rest of the surface
Onboard domain by domain. Track adoption (search count, consumer count, API-of-the-month). The catalog earns its value through coverage; partial catalogs are not trusted.
- Catalogs that nobody updates rot fast. Treat publication as ongoing, not a one-time event.
- Without a governance review, the catalog accumulates duplicate APIs and outdated specs. Set the rules at rollout, not after.
- Internal and partner-facing scopes have different security and content requirements. Mixing them invites accidental exposure.
- Federated ownership only works when the platform team owns the catalog tool and the business teams own the API specs. Trying to centralise both fails at scale.
