Bound the purpose
Define the record, direction, source of truth and operational owner.
Developers & API
Extend an accountable workflow, not an uncontrolled second database.
UnionStack exposes grouped OpenAPI documents and a separate allow-listed reference portal. Integrations use tenant-aware OAuth/OIDC authorization and remain subject to application permissions.
Integration sequence
Design for ownership and recovery.
Provider credentials and allow-listed access require deployment configuration. Keep secrets out of browser bundles and repositories.
Authorize
Use OAuth 2.0 authorization code with PKCE and tenant context.
Handle reality
Test denial, expiry, retry, idempotency and partial failure.
Retire safely
Remove credentials, stop jobs and confirm downstream retention.
Next step
Review the API against a real integration scenario.
