Source type
Typeform Source Configuration
Typeform sources receive form response webhooks and verify Typeform's signed webhook header.
Typeform configuration
Create a Typeform 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 Typeform delivery before it enters the routing workflow.

}Typeform request contract
FastHook computes base64 HMAC-SHA256 over the raw body and compares it to typeform-signature with the sha256= prefix.
Typeform headers
Preserve typeform-signature when sending Typeform 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.
typeform-signaturesha256= base64 HMAC-SHA256 signature over the raw body.
Typeform setup
- Create a Typeform webhook and paste the FastHook Source URL.
- Use the Typeform webhook secret as the FastHook Webhook Signing Secret.
- Route by form_response fields or form id when one source handles several forms.
