Darwin operating guide · Seller view
A unified API succeeds when it preserves the contract and makes every state observable.
The seller owns normalized mappings, request IDs, retries, connector drift, diagnostics, change notices, and the incident runbook.
- Preserve response shape and semantics until a versioned migration is accepted.
- Make asynchronous side effects retryable and idempotent.
- Roll out behind controls and prove rollback before retiring the previous path.

The provider delivers the interface, diagnostics, change controls, and service evidence.

The product team verifies behavior, failure handling, operating cost, and rollback.
Provide a normalized API, maintain connector mappings, and support the customer through authentication and first successful sync.
Pilot an HRIS integration against employee, employment, and group objects before rolling it out across a 30-connector catalog.
