Where to find all CRM association types in HubSpot

merc1er — Tue, 21 Oct 2025 21:56:23 GMT

I am looking for a list of all Hubspot defined association types (and their corresponding ID).

From https://developers.hubspot.com/docs/api/crm/associations, it is shown an example with:

"associationTypeId": 56

But it is not said where this 56 comes from of where to find other associations.

If someone has a link to a list of associations, that would be greatly appreciated! 🙏🏻

Hey, @merc1er 👋 I've been down this road myself 🫠 There is not a list to point you to. But there is an endpoint we can use. It's listed here — Retrieve association types.

/crm/v4/associations/{fromObjectType}/{toObjectType}/labels

This will return all associations and their typeIds Object > Object, Contacts > Deals, for example.

Here's an example I created for a different post. It's set up to get the associations from a custom object to contacts.

Request

{{API URL}}/crm/v4/associations/boat/contacts/labels

Response

{ "results": [ { "category": "USER_DEFINED", "typeId": 15, "label": null }, { "category": "USER_DEFINED", "typeId": 20, "label": "Pizza" }, { "category": "USER_DEFINED", "typeId": 17, "label": "tacos" }, { "category": "USER_DEFINED", "typeId": 22, "label": "Hamburger" } ] }

I know it is mildly annoying to not have a definitive list, but with the ability to create custom association labels between objects, I understand why it is set up this way.

Have fun building! — Jaycee

Thanks for the reply!

So to get the assiocation types, I need to call this endpoint with object types.

Now, would you know if there's a list of objects? I would need to know what available objects are to fill in the

toObjectType

field.

Thanks again!

That is exactly what I'm looking for.

I'm building an Upsert API using object creation and update APIs and Associations APIs.

When I create an object with associations, I don't need the `toObjectType` field. However, when I try to update to an existing object (which includes creating associations with an existing object), I need a `toObjectType`.

I need to get the `toObjectType` from the `associationTypeId`, but cannot find how to.

Thanks.

Hey, @JoshMamroud 👋

You can find all the HubSpot defined associationTypeId values here – Association type ID values.

Best,
