Webhooks vs Polling: The Right Way to Handle Payment Events

Payomatix EngineeringApril 10, 20256 min read

Why Polling Fails

Polling adds latency, wastes API quota, and still misses edge cases. At scale, you'll either DDoS your provider or miss critical state transitions.

Why Webhooks Win

Webhooks deliver state changes in near real time, exactly when they happen — no wasted requests, no race conditions, no missed events.

Doing Webhooks Right

  • Always verify the signature before processing.
  • Always return 2xx fast and process asynchronously.
  • Always be idempotent — the same event WILL arrive twice.
  • Always reconcile daily against settlement files in case of webhook gaps.

    • The Payomatix Approach

    Signed webhooks with at-least-once delivery, automatic retries with exponential backoff, and a replayable event log so you can recover from any outage.
