I see that we can now see object association history, but not for custom objects, at least not from what I can see. Would like to see this extended to custom objects as well.
Agree! I would love to see this as an option as well.
We really need this too. It’s important to be able to see how an association to a custom object was made in order to identify how inaccurate associations were made (employee error, import error).
Association history on standard objects is a great feature for troubleshooting and traceability. I assumed this was also possible for custom objects, and realize only after implementing a custom object that this feature is missing. Please add!
This is something we very much need as well.

Adding our voice to the mix,. We need this feature, and it makes perfect sense as a feature req since it just makes the hubspot behaviour uniform.
This would be really beneficial to see as our customers have Yachts and we need to keep a track of when the Yacht was bought (associated) by the client, when was it sold (association removed) and when a new yacht was bought (new association).
This would be a very useful feature so we can see the history of custom objects
Agree! It would be fantastic for custom objects
We primarily use custom objects to track our member data and it would be very helpful to track this!
Currently it seems that association history is only avaible between two default HubSpot objects. The assocition history is not visible/accessible between a default and a custom object, and neither between two custom objects. This means that there is no way to have accountability for association edits that involve custom objects at all!
https://app.hubspot.com/association-history/{{Portal ID}}/{{Object Type}}/{{Object ID}}/{{Object Type}}
Manipulating the association-history URL, with either object type being a custom object, yields this message, even for a super-admin:
“Your permissions don’t give you access to view this object type.
Talk to your account admin to change your access.”
The API doesn’t seem to have any ability to pull association history either.
This means that we don’t currently have any way of knowing which employee edited an association that involves a custom object. That is a massive accountability gap. This should definitely be visible in the UI and accessible via API, and potentially even accessible in reports.
Totally agree. This is also a big issue for us too for the same reasons cited by Greg
agreed and upvoted
+1 ! Super frustrating that this is not available.
Right now we track this in a roundabout way with custom properties (e.g. “Number of associated [custom object]: XX”) and then property history will show when that number has changed. But would be so nice to have this in the UI out of the box instead 
Hi @GregP there’s another Idea on the community with a bit more upvotes on this same topic (I think) → https://community.hubspot.com/t5/HubSpot-Ideas/Custom-Object-Association-History/idi-p/576062
Maybe it’s a good idea to all upvote that Idea & get to more upvotes on 1 post?
I really hope HubSpot can put this on the roadmap soon! Would be super useful. I have a custom coded workflow that associates contacts with a custom object, and when the workflow history says everything was excecuted perfectly; I want to be able to see if a user in my portal manually removed the association or if something went wrong with that workflow for example.
The history is so needed for troubleshooting from an ops side!
Adding another upvote. We recently created a Custom Object, and after a couple months’ use, we’re evaluating how the Custom Object is working for us. I’m unable to see when the Custom Object was associated with a Contact or the Company. There is no capability to audit how or when the Association between the Custom Object and a default Object was made; if it was made via automation/workflow or when the Custom Object record was manually created.
This would be an absolute necessity to increas our usage of HubSpot!
This is a necessity!! We are able to gain so many insights from seeing assocation history of other objects. Custom objects and their associations are just as essential to our business as deals, tickets, etc.!!
VERY much needed! Specifically in the case of customer assets, where an asset may get “returned” or “rental returnec” from one customer to another. An association history is a good way to see where the asset has been.
