Get Object Properties
Fetches all field definitions for a HubSpot record type (tickets, contacts, companies or deals), including custom fields and the values they accept. Useful for finding which fields exist before updating records.
Action identifier: get_object_properties. Reference checked: 29 September 2026.
Inputs
object_type
string
Required
The object type (e.g. tickets, contacts, companies)
Output shape
Paths are relative to this action's output. Select them from the builder's variable picker; do not add a ticket wrapper to actions that return top-level fields. Nullable property fields and empty defaults are not proof that a value was retrieved.
fields
list of objects
Property definitions for the selected object type, rather than values on an individual record.
fields[].name
string
Internal property name to use in reads, filters and updates.
fields[].label
string
Human-readable property label.
fields[].type
string
Property data type, such as string, number or enumeration.
fields[].fieldType
string
HubSpot field control type, such as a text input or dropdown.
exists
boolean
True when at least one property definition is returned.
llm_triage_metadata
string
Text summary of property names, IDs, descriptions and available choices or data types; No entries found when empty.
Open property/record objects may include additional HubSpot fields. Inspect the returned data rather than assuming every declared field is populated.
Behavior and limits
Returns property definitions, not values on a particular record. Use each property's internal name in reads/writes; labels are display text. llm_triage_metadata includes enumeration choices as label/value pairs when available.
Unknown object types or no returned definitions give exists: false, an empty fields list and No entries found metadata. HubSpot may return additional definition fields through the open output model.
