Could you clarify if you created a HubSpot form? Or are you using a non-HubSpot form and trying to get the data into HubSpot? I think it's the latter, but I just want to be sure.
My situation is as follows. I've already created a form and embedded it on my site. After the user undertakes it will be redirected to another page of my site. What I want is to get this data that the user has filled out and pass that parameters to the other page.
Sorry for the delay here, but what about using the onFormSubmit callback function (documented here:https://developers.hubspot.com/docs/methods/forms/advanced_form_options) to grab the values from the form when it's submitted? Then you could redirect the user to your page with the form field values appended in a query string, which would make those values accessible on your new page.
