FAQ
Frequently asked questions
- What events trigger webhooks?
- Webhooks are sent when single verifications complete or fail (a result reused from a recent check usually returns at once without one, but not always), when bulk verification jobs complete or fail, when your credit balance runs low or runs out, and for blacklist and DMARC monitoring alerts.
- What if my endpoint is down?
- Verification, job and credit events, and alerts from a scheduled monitor check, are attempted up to 3 times, with a short exponential backoff and a 10-second timeout per attempt (transient failures only). For verification, job and credit events all attempts share one time limit, so a retry can get less than 10 seconds. An alert from a manual monitor check is attempted once, with a 5-second timeout. If delivery ultimately fails, poll GET /v1/jobs/{job_id} as a fallback, or retry the delivery from your webhook logs.
- How do I verify webhook authenticity?
- Each webhook includes a signature header. Verify it using your webhook secret from the dashboard.
