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
- Replaced iframe embed with Webflow form
- Working HubSpot API integration script

- 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
