The code to call API handle subscription

Following our previous thread, we would like to add people to different lists based on the user type they select.

This is the code we used:

$array = array(1,2,13);
$curl = curl_init();
curl_setopt_array($curl, array(
CURLOPT_URL => site_url()."/wp-json/newsletter/v1/subscribe",
CURLOPT_RETURNTRANSFER => true,
CURLOPT_ENCODING => "",
CURLOPT_MAXREDIRS => 10,
CURLOPT_TIMEOUT => 30,
CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
CURLOPT_CUSTOMREQUEST => "POST",
CURLOPT_POSTFIELDS => "email=".$_POST['tiny_email']."&name=".$_POST['tiny_dispaly_name']."&lists=".$array."",
CURLOPT_HTTPHEADER => array(
"cache-control: no-cache",
"content-type: application/x-www-form-urlencoded"
),
));
$response = curl_exec($curl);
$err = curl_error($curl);
curl_close($curl);

With this code, users are added as a wordpress subscriber but not added to a target list.

We want to also add the user to respective lists.

Please advise. Thanks a lot.
