I'm trying to sync a mysql database to the contact list of Mailchimp. I cannot associate the Fname and Lname from the database to the Mailchimp field because they are not listed in mailchimp column.
When I run the integration, it gives only faults and in the error report it's indicated that the Fname and Lname is needed.
Your merge fields were invalid. Errors: Please enter a value(Field: 'FNAME');Please enter a value(Field: 'LNAME').
I've tried Merge Fields Behavior - Join all merge fields (and others) and API version 2 and 3. No go...
What I'm I doing wrong?
