When we extract activities from the bulk API, we don't see any of type 28, "Sync Lead Updates to SFDC." We do continue to get them through SOAP for the same dates.
The expectation I have is that Bulk extract of activities would have all activities for a time range. Does anyone know if these activities being excluded from the Bulk extract API?
I've found that the Bulk API isn't fully completed. If developers.marketo.com isn't helpful, I'd ask Support.
