Answer 1

It returns the following: failed to open stream: HTTP request failed! HTTP/1.1 401 UNAUTHORIZED

So, you have to be authorized.

You ca play with this code snippet (I can't test since token expired again):

<?php
$access_token = "s9spZax2Xrj5g5bFZMJZShbMrEVjIo"; // use your actual token
$url = "https://pardakht.cafebazaar.ir/devapi/v2/api/validate/com.pdgroup.insta/inapp/coin_follow_1/purchases/324234235/";

// Solution with file_get_contents
// $content = file_get_contents($url . "?access_token=" . $access_token);
// echo $content;

// Solution with CURL
$headers = array(
    "Accept: application/json",
    "Content-Type: application/json",
    "Authorization: Basic " . $access_token
);

$ch = curl_init();
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_VERBOSE, 1);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_URL, $url); //  . $params - if you need some params
curl_setopt($ch, CURLOPT_POST, false);
// curl_setopt($ch, CURLOPT_USERPWD, $userPwd);

$result = curl_exec($ch);
$ch_error = curl_error($ch);
$info = curl_getinfo($ch);

curl_close($ch);

if ($ch_error) {
    throw new Exception("cURL Error: " . $ch_error);
}

if ($info["http_code"] !== 200) {
    throw new Exception("HTTP/1.1 " . $info["http_code"]);
}

echo $result;
