I am trying to Opt in for a user based on email address, but getting error.
global $infusionsoft;
$infusionsoft->refreshAccessToken();
//opt in user
$billing = $order->get_address( $type = 'billing' );
$email = $billing['email'];
error_log('email is '.$email);
$optIn = $infusionsoft->emails('optIn', $email, 'I have Permission box was checked');
