Below are typical examples for sending paReq and backUrl to the sandbox environment. In production, you use the customerAction.url provided by the Start response.

      <input type="hidden" name="backUrl" value="https://yourdomain.com/example/backUrl.php" />
      <input type="submit" value="Authorize with 3DS" />
    </form>
  </body>

curl --location --request POST 'https://secure.sandbox.netopia-payments.com/sandbox/authorize' \
--form 'paReq="rcrO9tXAiBpwv-ZE4JQ4yeI..."' \
--form 'backUrl="https://yourdomain.com/example/backUrl.php"'

<?php

$curl = curl_init();

curl_setopt_array($curl, array(
  CURLOPT_URL => 'https://secure.sandbox.netopia-payments.com/sandbox/authorize',
  CURLOPT_RETURNTRANSFER => true,
  CURLOPT_ENCODING => '',
  CURLOPT_MAXREDIRS => 10,
  CURLOPT_TIMEOUT => 0,
  CURLOPT_FOLLOWLOCATION => true,
  CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
  CURLOPT_CUSTOMREQUEST => 'POST',
  CURLOPT_POSTFIELDS => array(
    'paReq' => 'rcrO9tXAiBpwv-ZE4JQ4yeI...',
    'backUrl' => 'https://yourdomain.com/example/backUrl.php'
  ),
));

$response = curl_exec($curl);
curl_close($curl);

echo $response;

note

Tip: The exact paReq value and customerAction.url are always returned by the Start endpoint for each transaction. Make sure to use the correct ones in your flow.
