Thanks, Pav. I reached out to Novak by phone and email. I did not get a response either way.
I also attempted to inset the Contacts (Exported) into a MySQL database and found there is a byte limit with attempting to use a flat table.
I have found ETL pipelines, such as HevoData, to make the API calls for us, however, I ran into one huge issue where the Keap API does not return the list of tags on a Contact if I call the Contacts in bulk. This only works if the contact is pulled individually. Given out 100k+ contacts, this would be very resource intensive.
For reference, Keap blocks the tags on a mass Contact pull because of resource issues on their end.
