Dear team,

For IPN , if my server is down at that time ? what would be ideal solution?

Hi rahul0611,

Our API allows you to send back a response that you were actually able to update your database using the code below:

if(DB_UPDATE_IS_SUCCESSFUL){
$resp="pesapal_notification_type=$pesapalNotification&pesapal_transaction_tracking_id=$pesapalTrackingId&pesapal_merchant_reference=$pesapal_merchant_reference";
ob_start();
echo $resp;
ob_flush();
exit;
}

If the server goes down before getting into <if> statement above, PesaPal will make an assumption that an update was not done and will call the IPN related to that specific transaction repeatedly till we get the response that you updated your database.

Hi Lazro,
if i am not sending the response as "pesapal_notification_type=$pesapalNotification&pesapal_transaction_tracking_id=$pesapalTrackingId&pesapal_merchant_reference=$pesapal_merchant_reference" , how many times will pesapal try?

Thanks

Hi,

IPN is called frequently till a status is returned. The longer the confirmation takes, the lower the frequency gets. Meaning soon it will be almost "obsolete". It's not off but the period between two IPN calls is quite long.

In such a case you may re-run the IPN manually from your merchant account.
