I’m not seeing an attachments array for CRM objects like the HubSpot company. Are attachments exposed on contact, company, or deal objects? Are there any plans to?
Attachments are exposed via the engagements API. So if you were to use the GET Associated Engagements endpoint you will see an attachments array in each engagement object, which is populated with file IDs which you can get access to via this endpoint.
Let me know if you have any questions about that.
