Calendly Source Configuration

Calendly sources receive invitee, routing, and scheduling webhooks with timestamped signature verification.

Calendly configuration

Create a Calendly source, keep POST and PUT and PATCH and DELETE enabled, and provide the configured Webhook Signing Secret values for provider signature. FastHook uses these settings to validate each Calendly delivery before it enters the routing workflow.

FastHook verifies calendly-webhook-signature by signing timestamp + '.' + raw body with HMAC-SHA256.

Calendly headers

Preserve calendly-webhook-signature when sending Calendly test deliveries. FastHook evaluates this request context before accepting the payload, so missing or modified values remain visible as rejected requests instead of routed events.

calendly-webhook-signature

Comma-separated t and v1 signature values.

Calendly setup

  1. Create a Calendly webhook subscription with the FastHook Source URL.
  2. Copy the webhook signing secret into FastHook.
  3. Use event type fields to split created and canceled invitee events.
