How do you handle integration failures and retries?

Every Laravel integration we ship handles failure properly. Network failures and 5xx responses get exponential backoff retries with jitter through Horizon queues. Rate limit responses (429) are throttled correctly using the integration's documented limits. Permanent failures (4xx) are logged with full context and surfaced for review rather than retried infinitely. Circuit breakers cut off integrations during sustained provider outages to protect the rest of the application. Failed webhook deliveries are stored with the raw payload for replay through an admin tool.
