How to sending many POST requests with cURL faster - api

Question

I have code to active various gaming platforms for player, the code is working well but it runs very slowly. How can I make it better and run faster?
<?php
$_SESSION['username'] = "demo123";
$password = "pass123";
$prefix = "HAN";
$gmusername = $prefix.$_SESSION['username'];
$gmpassword = $password;
$apikey = "SEFOQVBJOjEyMzQ1Njc4";
/////// WM ///////
$params = ['username' => $gmusername];
$curl = curl_init();
curl_setopt_array($curl, array(
CURLOPT_URL => "https://api.gmaster8.com/WM/player/active",
CURLOPT_CUSTOMREQUEST => "POST",
CURLOPT_POSTFIELDS => $params,
CURLOPT_RETURNTRANSFER => true,
CURLOPT_HTTPHEADER => array(
"Authorization: Basic $apikey"
) ,
CURLOPT_USERPWD => "$gmusername:$gmpassword",
));
curl_exec($curl);
/////// EVOLUTION ///////
$params = ['username' => $gmusername];
$curl = curl_init();
curl_setopt_array($curl, array(
CURLOPT_URL => "https://api.gmaster8.com/EVOLUTION/player/active",
CURLOPT_CUSTOMREQUEST => "POST",
CURLOPT_POSTFIELDS => $params,
CURLOPT_RETURNTRANSFER => true,
CURLOPT_HTTPHEADER => array(
"Authorization: Basic $apikey"
) ,
CURLOPT_USERPWD => "$gmusername:$gmpassword",
));
curl_exec($curl);
/////// IBC ///////
$params = ['username' => $gmusername];
$curl = curl_init();
curl_setopt_array($curl, array(
CURLOPT_URL => "https://api.gmaster8.com/IBC/player/active",
CURLOPT_CUSTOMREQUEST => "POST",
CURLOPT_POSTFIELDS => $params,
CURLOPT_RETURNTRANSFER => true,
CURLOPT_HTTPHEADER => array(
"Authorization: Basic $apikey"
) ,
CURLOPT_USERPWD => "$gmusername:$gmpassword",
));
curl_exec($curl);
////// and there are more than 20 other platforms need to be actived like that
?>
Is there any solution better to active many platforms? My code above is running without error but it takes too much time loading for player when registering and activing permision to access among gaming platforms.
