You can insert HubSpot properties into your document templates so that DocuGen populates them with the actual values when you generate a document or send it for signature. You can access the full list of properties when you use the Live editor, either when you create a new recipe or edit an existing one.

Explore properties

In this example, I will click Edit below the name of a template on an existing Deal recipe, but this applies to recipes on any object:

The list of all properties appears in the right panel of the Live editor:

The properties panel includes multiple accordions:

Deal lists all the Deal properties, such as Deal name, Deal close date, etc. If this recipe is related to a Company or a Contact or some other HubSpot object, the accordion will be for that specific object. Here is what you see if you click on the Deal accordion to expand it; each property includes the grayed out value from the current Deal record. You can also hover on the property to see its description:
Owner lists all the properties related to the record owner's user in HubSpot, such as email, first name, etc.
Primary Company lists the properties related to the Company marked as the primary one for this Deal. HubSpot allows one company as the primary one on a deal.
Contacts, Line Items, Quotes, Tickets, and other accordions with a plural name will populate repeating lists. For example, if you use the Annual contract value (property ID = hs_acv) under Line Items, this is the result:

Accordions with the word "table" will populate an actual table. For example, inserting the Line Items Table accordion will give this result:
