I recently set up a firebase site which is the reason why I need to convert a PHP cURL request to a jquery client-side request. The code below is working for cURL, it is a posting to Paypal.

// Init cURL
$request = curl_init();

// Set request options
curl_setopt_array($request, array
(
  CURLOPT_URL => 'https://www.sandbox.paypal.com/cgi-bin/webscr',
  CURLOPT_POST => TRUE,
  CURLOPT_POSTFIELDS => http_build_query(array
    (
      'cmd' => '_notify-synch',
      'tx' => $tx,
      'at' => $your_pdt_identity_token,
    )),
  CURLOPT_RETURNTRANSFER => TRUE,
  CURLOPT_HEADER => FALSE
));

// Execute request and get response and status code
$response = curl_exec($request);
$status   = curl_getinfo($request, CURLINFO_HTTP_CODE);

// Close connection
curl_close($request);

As I am inexperienced with ajax I'm quite unsure how to start or if it's possible...

My question how to convert this cURL request to jquery ajax.

Thanks a ton.

As charlietfl pointed out in the comments, Paypal isn't Cors enabled so this question is irrelevant. Sorry for wasting anyone's time...
