FormVerify for Webflow

Phone verification for HubSpot forms on your Webflow site.

When a visitor submits a protected HubSpot form on your Webflow site, FormVerify sends a one-time passcode (OTP) to their phone over WhatsApp or SMS. The form only reaches HubSpot once they enter it, so the leads your sales team gets have phone numbers that work.

Works with HubSpot’s legacy form editor

FormVerify protects HubSpot forms built in the legacy (classic) form editor and embedded with HubSpot’s embed code. On sites HubSpot doesn’t host, forms from the new editor load inside a HubSpot frame that FormVerify can’t reach. Forms your website builder makes itself aren’t covered either.

Set up on Webflow

About ten minutes, and your HubSpot form stays as it is.

  1. 1

    Embed your HubSpot form

    Paste HubSpot’s embed code into a Code Embed element on the page.

  2. 2

    Add FormVerify to Webflow

    Copy one snippet from FormVerify and load it on every page. The Webflow guide shows exactly where.

  3. 3

    Protect the form

    In FormVerify, switch protection on for the form and pick the field that holds the phone number.

WhatsApp or SMS, from your own accounts

Every plan includes both. hubglo adds no markup to messages; plans start at $69/mo.

WhatsApp

  • Sent from your own WhatsApp Business number, connected through Meta in a few clicks
  • FormVerify creates the OTP message template for Meta to approve
  • Meta bills you per OTP delivered, at its rate for the visitor’s country

SMS

  • Sent through your own Twilio account, to any mobile number
  • Twilio bills you at its normal rates
  • Connect it alongside WhatsApp and numbers not on WhatsApp get the OTP by SMS

Not sure which to use? WhatsApp OTP vs SMS compares cost, delivery and fraud risk.

Webflow gotchas

  • Webflow runs custom head code only on sites with a paid Site plan, so the snippet does nothing on a free webflow.io staging site.
  • FormVerify gates HubSpot forms embedded in Webflow. Native Webflow forms, built with Webflow’s own Form block, aren’t covered.

What it doesn’t do

FormVerify checks submissions in the visitor’s browser. It isn’t a server-side firewall, and someone posting directly to HubSpot’s form endpoint can skip it. Verified contacts can be marked in HubSpot, so anything that skipped the check is easy to filter out.
