Hello Constant Contact Support,
I would like to know if there is a Java based Constant Contact API / method that can be used to retrieve the list of contacts who are not associated with any of the contact lists in the Constant Contact account.
Thanks & Regards,
I would like to apologize for the delay in my response! You can get this information by using the ConstantContact.getContacts and using Contact.Status.REMOVED as the third parameter. This will work becuase the API considers a contact to be active only if they are assigned to a contact list.
If you have any further questions, please let me know!
