MDynamics365 Sync - No association mapping for Contact or Company?

PThomasFuelius — Thu, 10 Apr 2025 14:40:18 GMT

Hi guys,

When setting up a sync for a custom object, at the top of the list for the HubSpot side of the sync are all available associations. These have worked fine so far.

However when attempting to do the same for contacts and companies, no associations appear in the dropdown at all.

Are these associations somewhere else, or does the integration not allow this sort of flexibility for the core HS objects?

Hi @PThomasFuelius,

In HubSpot, association labels for standard objects like Contacts and Companies are not exposed in the same way as for custom objects when configuring third-party syncs like Dynamics 365.

Why you're not seeing associations in the dropdown:

HubSpot's data sync (including with Dynamics 365) only exposes association mappings for custom objects in that dropdown UI. For core objects (Contacts, Companies, Deals), the default associations (e.g., Contact to Company, Contact to Deal) are built-in and not manually configurable through the sync UI. That’s why you're seeing association options for your custom object but none for Contacts or Companies.

What you can do:

Use workflows or custom code to create associations post-sync. For example, you can trigger a workflow when a synced Contact is created or updated, then associate it with a Company using conditional logic or via custom coded actions if needed.
Use custom integration via Operations Hub (data sync + custom code). If you need full flexibility to map relationships during the sync itself, you may need to bypass native sync and use custom code actions or middleware like Zapier/Make or a custom API integration.

Hope this helps!

Hi PremKannan,

Thank you for your in-depth reply! HubSpot support came back to me with the exact same points you've made, but advised me that there are plans to roll out this functionality to the core objects in the future. Sadly there's no definitive time-frame on this.

I'll take a look into a workflow solution, much appreciated! Hope you have a wonderful weekend.

I am glad this helped!!

Thanks for your insight on the future roll out on this, to the native objects.. I can't wait to see it in action 🙏

You could use a third-party tool to sync data between the two platforms, such as Stacksync, Skyvia or even n8n if you're into building automation workflows. The easiest setup would be with Stacksync as it would allow you to sync associations as an ID relationship table (as it is currently set up in HubSpot). You would have to make sure the IDs you are using are correct or use a database in between to ensure proper data passing through.
