Add Engagement activities (calls, communications, emails, etc.) as database options for syncing via Hubspot’s Engagements API: https://developers.hubspot.com/beta-docs/guides/api/crm/engagements/engagement-details
The calls, emails, meetings, and tasks are available. Are there other databases that you’re looking for?
You’re totally right, I glossed right over the existing Engagements synced to Fibery because I was thinking of just the missing Engagements I’m interested, primarily LinkedIn messages. It’s under “Communications” group in Hubspot api: https://developers.hubspot.com/beta-docs/guides/api/crm/engagements/communications. Would probably be easy to support the Whatsapp and SMS types in Communications group as well, but I’m only interested in the LinkedIn messaging sync.
