I encountered a couple of issues integrating Pesapal, I'll list them below;
Issue #1
This;
include_once('oauth.php');
Should be (because of case sensitivity);
include_once('OAuth.php');
This;
$pesapalNotification=$_GET['pesapal_notification_type'];
$pesapalTrackingId==$_GET['pesapal_transaction_tracking_id'];
$pesapal_merchant_reference==$_GET['pesapal_merchant_reference'];
Should be this instead since we are assigning not comparing;
$pesapalNotification = $_GET['pesapal_notification_type'];
$pesapalTrackingId = $_GET['pesapal_transaction_tracking_id'];
$pesapal_merchant_reference = $_GET['pesapal_merchant_reference'];
Demo endpoint in the IPN listener should not be HTTPS.
Issue #4
On the demo code, you have this when getting the transaction status;
$request_status->sign_request($this->signature_method, $consumer, $token);
This results in an error .. for example, $this in code was my class which had no signature_method. Checking the iframe code there was this;
$iframe_src -> sign_request($signature_method, $consumer, $token);
where $signature_method had been defined as;
$signature_method = new OAuthSignatureMethod_HMAC_SHA1();
The line above is missing in the IPN listener code so the signature method is undefined.
Issue #5
While the code was a very good guide in making the API requests for the IPN listener it isn't clear on what to do after getting the $status.
In fact … I had to echo $status to finally piece together that it was the response. Seems obvious but extra commentary would go a long way which I've included.
The code for this part is too big to include in this email so have a look at this link for the IPN listener code from Line 62 there;
https://github.com/itsmrwave/pesapal-php/blob/master/pesapal-ipn-listener.php#L62
It describes to a bit more details what response to expect from pesapal and what to do. IE … from what I gathered;
- COMPLETED - update DB that the payment was confirmed then send Pesapal the data back to confirm success so that they don't keep pinging the IPN
- FAILED - update the DB that payment failed and then send Pesapal the data back to confirm that you acknowledge this so that they don' t keep pinging the IPN
- PENDING - do nothing … don't send pesapal anything so that they keep trying to ping the IPN till there's a change in status to COMPLETE or FAILED
Issue #6
Not really an issue but I just improved readability a bit … breaking long statements to a new lines … formatting …. indentation … enation of strings etc.
