Association Limits on schemas through API

It does not appear to be possible to defined association limits on Custom Object schemas defined through the API. (Currently using the Python hubspot-api-client==11.1.0

When defining Object Schemas, it is possible to create associations to other Custom Objects as well as HubSpot’s own objects, but it does not appear to be possible to define the Object Association limits through these APIs.

All Associations are created with MANY_TO_MANY association limits, and the only way to change these limits is through the UI.

Is there any one to define a One to Many, or One to <N> associtaion limit the schema level?

Update: I notice in this announcement post from 2023 that exposition of these new association limits was not available through the API at launch. We are now 18 moths past that. Are these association limits planned to reach the APIs, or will this only ever be a feature in the UI?

@MrLuke - Since the HubSpot libraries pretty often lag functionality that’s offered in the full API definitions, I am typically using the ‘bare metal’ python request functionality to support the more advanced functionality that’s available. Its pretty easy to transition to this way of working - and avoids debvugging a whole other layer of potential problems.

Best of luck!

Hi @SteveHTM. Thanks for the advice.
The API documentation (language non-sepcific) do not seem to include the cardinality features of Associations. Is there another reference you use to see the latest available APIs that might expose a feature before a client library does?

I see references to the calls I think you need here on:

You’re absolutely right. I had been stuck poking around in the V3 documentation.
Thanks, @SteveHTM.
