Hi @MBin,
Welcome to the Community!
Are you wanting to create a Hubspot form that syncs to Wordpress or a Wordpress specific form for your Hubspot site?
If your wanting to create a Hubspot form I’d recommend to check out this resource.
Looking forward to your response and clarification!

Hi @MBin , good question, and Cassie’s clarification is exactly the right starting point.

If your goal is to keep using that custom ACORD fillable form on WordPress and send submissions into HubSpot, then you generally have three realistic options with how HubSpot works in 2025.

The simplest is to replace the custom form with a HubSpot form (embedded on WordPress).

HubSpot’s WordPress plugin or embed code handles submission, tracking, prefill, and contact creation automatically. This is the cleanest path if you can accept HubSpot’s form UI and validation rules. HubSpot covers this approach here: https://knowledge.hubspot.com/forms/add-hubspot-forms-to-your-wordpress-site

If you must keep the existing custom form, the most common approach is to post the form data directly to HubSpot via the Forms API. In that setup, your WordPress form submits as usual, and on submit you send the field values to HubSpot using the API endpoint. This still creates or updates contacts properly, but you’re responsible for mapping fields and handling validation and errors on the WordPress side. HubSpot documents that flow here: (Add HubSpot forms to WordPress pages and posts (legacy) )

A third option, which some teams overlook, is embedding a HubSpot form inside an iframe or modal triggered by your custom form flow. That keeps your UX mostly intact while letting HubSpot handle submission and CRM logic, though it’s more of a workaround than a true integration.

One important thing to keep in mind: if the ACORD form has very complex conditional logic or file uploads, the Forms API route is usually the most flexible, but also the most technical.

Quick clarifying question to help point you in the right direction: do you need to preserve the exact ACORD form structure and behavior, or are you open to recreating it using HubSpot form fields on WordPress?

Once that’s clear, the best path becomes much more obvious.
