Guide
A practical framework.
Use this guide as a starting point for requirements, implementation planning or an architecture review.
1. Define the contract
Document identifiers, payloads, event semantics, authentication, ownership and expected latency.
2. Select the API pattern
Choose the interaction that matches the business use case instead of forcing every workflow through the same endpoint pattern.
A reliable API integration begins with explicit contracts: identifiers, payloads, authentication, idempotency, retries, rate behavior, observability and failure ownership. Test malformed payloads, duplicates, partial failures and downstream messaging effects. Document which system owns each field so changes can be reviewed before they affect customer-facing journeys.
