Replace HubSpot iframe with native form and API sync

Description:

We’re looking for a Webflow developer with experience integrating HubSpot forms without iframes, customizing embedded forms, and modernizing modal UI/UX.

Our website thesalesnerd.com currently uses a HubSpot form embed inside a Webflow modal. Because the form loads in an iframe, our CSS cannot style the email input and submit button to meet our design goals.

We need someone who can:

✅ Replace the iframe HubSpot form with a native Webflow form

✅ Submit that form to HubSpot via the HubSpot Forms API

✅ Preserve all HubSpot tracking + workflows + email automation

✅ Style the form inline (email + button tight appearance) on desktop/mobile

✅ Maintain our existing modal and page layout

✅ Deliver a clean UX that feels premium and conversion-focused

The long-term goal is to improve conversion and reduce friction while ensuring data lands in HubSpot exactly the same as it does today.

Responsibilities

• Build the modal form in Webflow (email input + button)

• Write the JS to post submissions to the HubSpot Forms API

• Ensure HubSpot contact creation & workflows trigger correctly

• Make the form layout tight and modern (inline on desktop)

• Maintain responsiveness/mobile behavior

• Add any necessary CSS/JS (preferably scoped, no global overrides)

• Test end-to-end (Webflow → HubSpot → success state → workflows)

• Provide clear instructions (or implement) for HubSpot workflows if needed

Your Skills / Experience

We want someone who has:

✔ Strong Webflow development skills

✔ Experience integrating with the HubSpot Forms API

✔ Clear understanding of native Webflow forms vs HubSpot iframe embeds

✔ Comfortable writing scoped CSS and JS

✔ Good UX judgment (especially on modals/forms)

✔ Experience with conversions / lead capture optimization

✔ Ability to QA cross-browser and on mobile

Bonus: familiarity with HubSpot workflows and double opt-in email logic.

Deliverables

  1. Replaced iframe embed with Webflow form

  1. Working HubSpot API integration script

  1. Clean CSS for inline layout (desktop + mobile stacking)

  1. Tested contact capture + HubSpot funnel tracking

  1. Optional: improved success state (thank you / redirect / email)

What This Project Is Not

✘ A full redesign of the site

✘ Building new pages

✘ Major UX overhauls unrelated to the modal

✘ Creating a standalone form solution separate from HubSpot data

How To Apply

Please respond with:

  1. Examples of similar work (Webflow + HubSpot form API)

  1. A brief explanation of how you’d implement this

  1. Your rate or estimate (fixed price or hourly)

  1. Availability / estimated timeline

  1. If you would be doing the work yourself or a team you manage.
