Formstack supports webhooks as an alternative to using our API. You can read more about webhooks at webhooks.org. You can also use webhooks as a supplement to our API using resthooks. You can read more about resthooks at resthooks.org

To set up a webhook, go to Settings > E-mails & Redirects > After the form is submitted and choose “Send Data to an External URL (WebHook)” when creating your submit action.

You will then paste in your webhooks URL and (optionally) your handshake key. Click “OK” and then “Save Settings” and you're done.
