I am trying to integrate Pesapal on an application built on the Symfony 2 Framework. I've used the sample PHP code but it is constantly giving me an "Problem: signature_invalid | Advice: > | " error when it comes to displaying the iframe. The consumer_keys and secret have been set up correctly.
Here is my integration code:
$consumer_key = 'XXXXXXXXXX'';
$consumer_secret = 'YYYYYYYYY';
$token = $params = NULL;
$signature_method = new \OAuthSignatureMethod_HMAC_SHA1();
$iframelink = 'http://demo.pesapal.com/api/PostPesapalDirectOrderV4';
//Grab payment details
$amount = $request->request->get('total');
$amount = number_format($amount, 2);//format amount to 2 decimal places
//$amount = number_format($amount, 2, '.', '');
$desc = $request->request->get('description');
$type = 'MERCHANT'; //default value = MERCHANT
$reference = $request->request->get('reference');//unique order id of the transaction, generated
$first_name = $request->request->get('first_name'); //[optional]
$last_name = ''; //[Optional]
$email = $firm_email;//Firm email is set at the beginning of the controller
$phonenumber = '';
//Build XML request
$post_xml = "<?xml version=\"1.0\" encoding=\"utf-8\"?><PesapalDirectOrderInfo >";
$post_xml = htmlentities($post_xml);
//Send
$consumer = new \OAuthConsumer($consumer_key, $consumer_secret);
//post transaction to pesapal
$iframe_src = \OAuthRequest::from_consumer_and_token($consumer, $token, "GET", $iframelink, $params);
$iframe_src->set_parameter("oauth_callback", $callback_url);
$iframe_src->set_parameter("pesapal_request_data", $post_xml);
$iframe_src->sign_request($signature_method, $consumer, $token);
//$iframepage .= $iframe_src;
$iframepage .='<!DOCTYPE html>
<html>
<head>
Pay Via
</head>
<body>
<p>Unable to load the payment page</p>
</body>
</html>';
return new Response($iframepage);
What could be the problem?
