Help with PHP/cURL to handle OAUTH2

API Discussion
1

Heya, a while ago someone helped me by giving me the below function to get the token for OAUTH2. Up until January it was working fine & I’ve come back to it this week and it doesn’t work now. Does someone know if something has changed with the API and I need to amend the code or does the following code work for them & it’s something I’m now doing wrong/up with my new Apache server?

<?PHP

// OAUTH2 Log in
 function getToken() {
   //curl -u {client_id}:{client_secret} -d grant_type=client_credentials https://us.battle.net/oauth/token
   $client_id = 'YOUR_ID';
  $client_secret = 'YOUR_SECRET';
  $url = "https://eu.battle.net/oauth/token";
  $params = ['grant_type'=>'client_credentials'];
   $curl = curl_init();
  curl_setopt($curl, CURLOPT_POST, true);
  curl_setopt($curl, CURLOPT_URL, $url);
  curl_setopt($curl, CURLOPT_POSTFIELDS, $params);
  curl_setopt($curl, CURLOPT_USERPWD, $client_id.':'.$client_secret);
  curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
   $result = json_decode(curl_exec($curl));
   curl_close($curl);
  return $result->access_token;
}

// Download JSON function	
function gzipGet($url) {
    $ch = curl_init();

    curl_setopt_array($ch, [
        CURLOPT_URL            => $url,   // Fetch this URL
        CURLOPT_FOLLOWLOCATION => true,   // Follow redirects
        CURLOPT_MAXREDIRS      => 3,      // Follow this many redirects at most
        CURLOPT_RETURNTRANSFER => true,   // CURL exec returns data into variable
        CURLOPT_SSLVERSION     => 6,      // Use TLSv1.2 for SSL connections, required by battle.net
        CURLOPT_TIMEOUT        => 20,     // Seconds
        CURLOPT_ENCODING       => 'gzip', // Use gzip transfer encoding, if available
    ]);

    $data = curl_exec($ch);
    curl_close($ch);

    return $data;
}


//call OAUTH2 function and set it to $token var
$token = getToken();

echo $token;
?>

Hello.

Perhaps this topic might help you out.

It looks like your code is ok, in January a new data policy was applied. Probably all you need to do is manage your client credentials and accept the new terms of service.

Hi Schiller thank you for taking the time to reply. You were correct, the new data policy & accepting the new ToS has solved it!
