Production integrations should enforce strict credential handling, predictable retry rules, and idempotent client behavior where supported.
Security and access controls
Store credentials securely and rotate on incident or ownership changes.
Use least-privilege scopes/roles for integration identities.
Log request identifiers and error codes for traceable support escalation.
Rate-limit and idempotency guidance
Handle `429` responses with controlled retry delay and backoff.
Use idempotency keys where API workflows support them (for example chat send-message flows).
Treat duplicate-submission risk explicitly in client design for order/payment-adjacent actions.
Technical support expectations
Share endpoint, request ID, timestamp, and sanitized payload when reporting issues.
Include environment, expected behavior, and observed behavior in every ticket.
Good observability and deterministic retry behavior are the fastest path to stable integrations.
