Webhooks are used to integrate your post submissions with third-party applications. When you set up a webhook, every time your form receives a new submission a POST request will be triggered to your configured URL containing your submissions data. This request can be used to process or store your data with third-party applications, trigger builds or other functions, or to be handled by your own custom server.
You can set your webhook from your form dashboard . On your form dashboard, navigate to the 'Settings' tab and you will see a panel titled 'Webhook'. In that field you can see what the target URL is currently set as and update it to a different URL.
After you enter a URL and click 'Update webhook' your webhook will immediately be activated. Any new submissions that come in will trigger a POST request to this URL.
