Can anybody help me connect This Api To Mylaravel shopping Cart For Payment

Have you even looked at the docs or tried something?

<?php
$reference = [
    "amount"        => "9701.84",
    "end_datetime"  => "2018-12-31",
    "custom_fields" => [
      "invoice" => "2018/0333"
    ]
];

$data = json_encode($reference);

$curl = curl_init();

$httpHeader = [
    "Authorization: " . "Token " . "reh8inj33o3algd2tpi6tkcnrqf8rjj2",
    "Accept: application/vnd.proxypay.v2+json",
    "Content-Type: application/json",
    "Content-Length: " . strlen($data)
];

$opts = [
    CURLOPT_URL             => "https://api.proxypay.co.ao/references/904800000",
    CURLOPT_CUSTOMREQUEST   => "PUT",
    CURLOPT_HTTP_VERSION    => CURL_HTTP_VERSION_1_1,
    CURLOPT_RETURNTRANSFER  => true,
    CURLOPT_TIMEOUT         => 30,
    CURLOPT_HTTPHEADER      => $httpHeader,
    CURLOPT_POSTFIELDS      => $data
];

curl_setopt_array($curl, $opts);

$response = curl_exec($curl);
$err = curl_error($curl);

curl_close($curl);
