function ApiRequest($method, array $req = array())
{
    // API settings
    $url = 'https://your-api-url-here.xxx';;
    $token = ''; // your API-Token
    $req['method'] = $method;    //change your method here
    // generate the POST data string
    $post_data = http_build_query($req, '', '&');
    // generate the extra headers
    $headers = array();
    $headers = array(
        'X-Token: ' . $token,
        'Content-Type: application/json' //application/x-www-form-urlencoded
    );

    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_POST, 1);
    curl_setopt($ch, CURLOPT_POSTFIELDS, $post_data);
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);  
    curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);

    $result = curl_exec($ch);
    if (curl_errno($ch)) {
        echo 'Error:' . curl_error($ch);
    }
    curl_close($ch);
    return $result;
} 

Provides your method and request parameter in an array

$method = 'payloadSend'; // or something else
$params = ['a' =>'aaaaa', 'b' =>'bbbbb', 'c' =>'ccccc', 'ect' => '....'] 

calls the function:

$call = ApiRequest($method, $params)
$decode_res = json_decode($call, true);
print_r($decode_res)

I hope this useful.
