I am attempting to retrieve associations between specific objects using the provided endpoint:

/crm/v3/objects/{fromObjectType}/{fromObjectId}/associations/{toObjectType}

In particular, I am aiming to gather associations between contacts and tickets using the following endpoint:

https://api.hubapi.com/crm/v3/objects/contacts/7274956712/associations/Ticket?limit=100&archived=false

The response, however, only includes HubSpot-Defined association types, excluding custom ones:

However, I successfully get the associations when executing a GET request to:

https://api.hubapi.com/crm/v3/objects/contacts?limit=100&associations=Ticket&archived=false ​

Response:

2 years ago the response was returned in a different format:

https://api.hubapi.com/crm/v3/objects/companies/6266951100/associations/Contact?limit=100&archived=false

{
 "results": [
 {
 "associationTypes": [

 "typeId": 2
 }
 ],
 "toObjectId": 101
 },
 {
 "associationTypes": [
 {
 "category": "HUBSPOT_DEFINED",
 "label": null,
 "typeId": 280
 },
 {
 "category": "HUBSPOT_DEFINED",
 "label": "Primary Company",
 "typeId": 2
 }
 ],
 "toObjectId": 151
 }
 ]
}

Could there have been changes in API behavior or have I overlooked something?

There is a newer v4 version of the Associations API you can try and see if it acts any different. /crm/v4/objects/{objectType}/{objectId}/associations/{toObjectType} Accounts Dashboard | HubSpot
