Webhook Development

Reliable webhook handling that doesn't break when services send duplicate events or timeout.

What We Build

  • Signature verification (Stripe, Shopify, GitHub)
  • Idempotency handling (no duplicate processing)
  • Retry logic with exponential backoff
  • Background job queues (Sidekiq, Bull)
  • Webhook logging & debugging tools

Common Problems We Fix

  • Webhooks timeout and fail silently
  • Duplicate events process twice
  • No retry mechanism when processing fails
  • Signature verification missing (security risk)
  • No visibility into webhook failures
