How to Build a Webhook System in Rails Using Sidekiq
a day ago
- A webhook system can be built in Rails using Sidekiq for async processing and retries.
- Define WebhookEndpoint and WebhookEvent models with subscriptions and enabled status.
- Create a WebhookWorker to deliver events via HTTP POST, handling errors like timeouts using pattern matching.
- Use BroadcastWebhookService to queue events for subscribed endpoints.
- Improve retry cadence with exponential backoff and jitter, limiting to 10 retries over ~3 days.
- Implement event subscription and endpoint disabling to reduce costs and improve performance.
- Use Ruby pattern matching for special-case handling, e.g., ngrok tunnel errors.
- Caveats include validating endpoints for TLS, avoiding loops, and handling response size.
