I am trying to add subscriber to list through Getresponse api for single contact subscription to list i have to call api like this
$getresponse = new GetResponse(api key);
$result = $getresponse->addContact(listid,
$lead['name'],
$lead['email']
);
Now i want to add multiple emails at a single call, i cant use foreach loop for each contact, is there a function or endpoint to add multiple emails at a single call?
