Why it matters

Building reliable webhook infrastructure is complex. Form Platform handles delivery, retries, and security so you can focus on processing events, not managing infrastructure.

FAQ

You can subscribe to multiple webhook events including response.created (new form submission), event.view (form page viewed), event.focus (field focused), event.submit (form submitted), event.error (validation error), and event.abandon (form abandoned). Each webhook can be configured per form or globally.

All webhooks include HMAC SHA-256 signatures in the X-Webhook-Signature header. You can configure a secret when creating a webhook and verify the signature to ensure requests are authentic. Always use HTTPS endpoints and verify signatures before processing.

Form Platform automatically retries failed webhook deliveries with exponential backoff. We attempt up to 3 retries before moving the webhook to a dead-letter queue. You can view delivery status and retry history in the dashboard.

Webhooks use OpenTelemetry format with resource metadata, event details, and trace information. For backwards compatibility, legacy fields are also included. Payloads are JSON and include all relevant event data including form ID, response ID, timestamps, and event attributes.
