formstack-webhooks

Receive and verify Formstack Forms webhooks (the "WebHook" submit action, aka "Send Data to an External URL"). Use when setting up a Formstack form submission webhook handler, debugging X-FS-Signature HMAC verification, handling application/x-www-form-urlencoded or JSON submission payloads, or working out which fields a form will POST. Formstack has NO event types — a WebHook fires on exactly one thing, a form submission — so handlers key off FormID, not an event name.
