Order ID at Paypal mail

-- HikaShop version -- : 2.3.4
-- Joomla version -- : 3.3.3

Hello, I would like to ask how can we change the appearing Invoice ID: (order number) at the Paypal notifications to Order ID instead.
Please see the screenshot. This is the email customer gets from paypal and comes also to us upon payment is complete.
As we give to users invoices with other numbers than these (order id 533 and invoice id: z123.....) , that could led to confusion. We prefer there to show the Order Id: 533 instead. Is this a configuration at paypal.php file?

Thanks a lot in advance for your suggestions.

Hi,

You will have to edit the file "paypal.php" or "paypal_end.php" in the paypal plugin.
