Webflow Forms to Webhook

Webflow forms can be redirected to a webhook for external processing, by specifying the action in Webflow’s designer. This gives you a lot of capability, including business logic and immediate processing of your form data, however Webflow does not have any in-built way to handle the webhook’s response.

By default, instead of a “success” message, the user sees the JSON response itself- which is not an ideal user experience. Alternatively, you’re forced to create a thank you page, exclude it from search engines, etc- when often all you wanted was a success message.

The WFU forms handler bridges that gap;

  1. It submits your form directly to the webhook you choose.
  2. It analyzes the response to determine success or failure.
  3. It then displays the form success or failure message, depending on that result.

Because each webhook provider responds differently, we have several “handlers” for each situation;

  • The Zapier handler looks for “success” in the response, and displays the success message if it is present. However it’s important to note that Zapier’s success response only indicates that the data was received successfully. It does not indicate that the Zap ran successfully.

  • The Make (Integromat) handler can handle specific responses and display error messages.

  • The n8n handler can handle specific responses and display error messages.

  • The Other handler always displays the success message. It’s most useful for unknown webhookd providers, and in situations where success/failure aren’t that important, you just need to indicate to the user that their work is done. Use it for simple and less essential form submissions, like newsletter enrollments.

Key advantages

  • Immediate form processing, with no delays. If you’ve used e.g. Zapier’s Webflow trigger, it polls for new forms and can take 10 minutes for a form submission to be detected.

  • No need to use Webflow’s built-in forms email notification system. You can go direct to a Sales Force Automation (SFA) system, or to your own email notification with no unsubscribe link problems.

  • No form submission limits.

  • Make the form behave like a normal webflow form post, where it stays on the same page, and displays the form’s success message.

  • Handle error scenarios better, including unique server side logic and error messages ( with Make & n8n ).

Getting Started ( NOCODE )

STEP 1 - Add the Library

Install this JS in BODY, site-wide or on the specific pages you want the script to affect.

<script type="module" src="https://cdn.jsdelivr.net/gh/sygnaltech/webflow-util@4.11/src/nocode/webflow-form.js"></script>

Unlike most WFU elements, custom attributes are not needed.


  • Setup your Zapier webhook

  • Copy the webhook URL and in the Webflow designer, paste it into the Action setting of the form.

  • Design the form however you like

  • Make sure to customize your success and fail messages too.

STEP 3 - Mark your Form for WFU’s handler

Open the left-side Navigator panel in Webflow’s and select the Form Block element ( not the Form element ). On the Form Block element, add a custom attribute of wfu-form-handler, and specify the handler you want;

  • Use zapier for Zapier webhooks.

  • Use make for Make ( Integromat ) webhooks.

  • Use n8n for n8n webhooks.

  • Use other for all other webhooks.

Each will behave slightly differently in how it processes the response, since each webhook service does responses differently. See notes above.
