Sending Additional Data from ACF Fields

Hey @fatihturan,

Thanks for reaching out to us.

Please check the example code at https://github.com/ibericode/mc4wp-snippets/blob/master/forms/programmatically-add-fields.php. You will need to use this code and modify it to get the ACF field data and then you can send it to MailChimp.com using our form.
