Integrations That Don’t Break: Monitoring & Reconciliation Basics

Integrations fail for predictable reasons: rate limits, transient network issues, schema drift, and unexpected nulls or edge cases.

Design for idempotency and retries. If an order sync runs twice, the outcome should remain correct—not duplicated.

Add reconciliation. Daily checks that compare system totals catch errors before customers do.

Finally, treat logs and alerts as part of the product: clear error messages, correlation IDs, and dashboards save hours during incidents.
