sync process on custom objects
In my Marketing database, I have my contacts which are synced from Salesforce. I also have a custom object linked to contacts which is synced as well.
The custom object is getting synced regularly, but is it being synced because the contact linked to it is getting synced? Or is it getting synced because it's timestamp is getting updated?
To explain it better:
1) salesforce custom object record updated, then salesforce contact object record updated.
a) result: both records are updated to Marketo when it next syncs.
2) Salesforce custom record is updated and salesforce contact object record is NOT updated.
a) Will the Salesforce custom record be synced or do I need to update the salesforce contact object to get it to sync?
