Reliability & Resilience

Webhooks fail. Networks are unreliable, servers go down, and deployments cause outages. These guides cover the patterns and strategies for building webhook systems that handle failure gracefully.

📄️Webhook Retry Strategies

Webhook retry strategies that work: exponential backoff schedules, jitter to prevent thundering herds, and knowing when to stop retrying failed deliveries.

📄️Idempotency and Deduplication

Idempotency and deduplication for webhooks: why duplicate deliveries happen and how to track event IDs so your handler processes each event exactly once.

📄️Webhook Timeout Best Practices

Webhook timeout best practices: why providers cut you off in 5-30 seconds, and how the acknowledge-first pattern keeps handlers fast and avoids retries.

📄️Webhook Delivery Guarantees

Webhook delivery guarantees compared: what at-least-once, at-most-once, and exactly-once mean in practice, and how each affects your webhook consumer.

📄️Dead Letter Queues for Webhooks

Dead letter queues for webhooks: capture deliveries that exhaust their retries, decide which failures belong in the DLQ, and replay them safely.

📄️Circuit Breakers for Webhook Delivery

Circuit breakers for webhook delivery: how the closed, open, and half-open states stop retry storms against failing endpoints, with a Python implementation.
