/******************************************************
DoAuthorizationReceipt.php.

Sends a DoAuthorization NVP API request to PayPal.

The code retrieves the authorization ID, amount, currency
and constructs the NVP API request string to send to the
PayPal server. The request to PayPal uses an API Signature.

After receiving the response from the PayPal server, the
code displays the request and response in the browser. If
the response was a success, it displays the response
parameters. If the response was an error, it displays the
errors received.

Called by DoAuthorization.html.

Calls CallerService.php and APIError.php.

******************************************************/

// clearing the session before starting new API Call
session_unset();

require_once 'CallerService.php';

session_start();
