How to map ConvertFlow fields to HubSpot custom fields

Mapping form custom fields to HubSpot custom fields

When adding custom fields to ConvertFlow form elements, you can choose to select from "HubSpot fields". This allows you to map contact info entered into the ConvertFlow custom field, into the correct contact custom field in HubSpot.

Mapping survey fields to HubSpot custom fields

When you create a survey element in ConvertFlow, click on the "Map to custom field" dropdown to the right in the builder panel, and you can select from your HubSpot custom fields.

Mapping preset ConvertFlow fields to HubSpot custom fields

On your website's integrations page, when you have HubSpot connected, you'll see a "Fields" button, that when clicked, allows you to map ConvertFlow's preset contact fields to HubSpot custom fields. 
This is useful for mapping contact info added to ConvertFlow's preset contact fields, that aren't already mapped to fixed fields in HubSpot. For example, "first name" and "email address" are already mapped to HubSpot's contact fields for you.
Just enter the data name of the HubSpot custom field you would like ConvertFlow's preset fields to be mapped to, and you're set!
