Typical integration patterns
- REST API clients with explicit timeouts and error mapping.
- Webhook receivers with signature validation where supported.
- Queue-backed asynchronous processing.
- Idempotent operations to reduce duplicate side effects.
- Scheduled reconciliation when webhooks are incomplete or unavailable.
- Audit logs for externally visible state changes.
Reliable synchronization
Two systems rarely share the same data model or timing. Integration logic should define which system owns each field, how conflicts are resolved, what is retried and how stale or missing remote data is surfaced.
Rate limits and backpressure
High-volume imports or exports should respect provider rate limits and use queues or batching rather than tying long-running synchronization to a browser request.
Failure visibility
An integration is not complete when successful requests work. Operators also need to see failed jobs, retry state and enough context to understand what needs intervention.
