I'm using the old Constant Contact API -- ( ie: http://api.constantcontact.com/0.1/API_AddSiteVisitor.jsp ).
Right now, .. I am successully interfacing with the API and adding contacts, and passing the following field values:
However .. I can't seem to figure out what field name to use for the Home Phone, .. or for any of the Custom Fields.
I tried using "home_number" for the phone number, .. and also "Custom_Field1" for one of the custom fields -- but none of these seem to be working.
Please advise on what field names I should be using for the Home Phone & Custom Fields.
