Pass form data from Hubspot to custom HTML form fields for app signup

forms

#1

We are trying to send prospects to a landing page with a Hubspot form where they signup for a free trial /discount offer on an application. Once they submit the Hubspot form, the return URL is the first step of the app signup system that is custom built (not a Hubspot form) - so we’d like the Hubspot form data to pass to the redundant fields on the first step of the app sign up - so that users do not have to enter the same information twice. Here’s the landing page, and the app form URL that our dev team provided.

HUBSPOT LANDING PAGE:

APP SIGNUP - SET AS THE RETURN URL AFTER SOMEONE SUBMITS HUBSPOT FORM ON THE LANDING PAGE ABOVE (CUSTOM - NOT HUBSPOT)
