Get Association Types
Fetches the possible relationship types between two kinds of HubSpot records, for example between tickets and contacts. Use this to find the correct association type ID before associating objects.
Action identifier: get_association_types. Reference checked: 29 September 2026.
Inputs
from_object_type
string
Required
Source object type (e.g. tickets)
to_object_type
string
Required
Target object type (e.g. contacts)
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.
results
list of objects
Association type definitions for the requested source-to-target object pair.
results[].typeId
integer
Association type ID for this direction and category.
results[].label
string | null
Display label; null for an unlabelled association.
results[].category
string
HubSpot association category, such as HUBSPOT_DEFINED or USER_DEFINED.
exists
boolean
True when at least one type definition is returned; false for no definitions or an unknown object-type pair.
llm_triage_metadata
string
Text summary of labels, type IDs and categories; 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 association types for the specified ordered object-type pair. The reverse direction can use a different type ID. Preserve category as well as typeId when interpreting results; the list may include user-defined labels.
No returned types or an unknown pair gives exists: false. This flag concerns returned type definitions, not existence of two individual CRM records. Unlabelled entries are described as Unlabeled in metadata.
