How to Track Newly Added or Removed Associations via API

Hello,

I am integrating HubSpot CRM and need guidance on efficiently tracking associations.

1. When I add a ticket to a contact (or vice versa), I noticed that only the ticket’s lastmodifieddate updates, not the contact’s.

   • Is there a way to have the contact’s lastmodifieddate update on association changes?

2. I want to incrementally sync only newly added or removed associations without scanning all contacts or tickets.

   • Is there an API endpoint or parameter to return only association changes since a specific timestamp?

3. Are there any best practices for syncing associations at scale efficiently, including rate limits or batching recommendations?

Essentially, I need to track association changes efficiently for large datasets, ideally without full scans. Any guidance or examples would be appreciated.

Thank you for your support!
