Local Payment Gateway, Some questions!

Hello,
I have some questions about a local payment gateway here in Kuwait.

When the customer order something --> The store redirect him to the Local Payment Gateway --> After paying me, then I must show some IDs from the payment gateway --> in the page index.php?route=checkout/success I need to put a customized page only for this local payment gateway, let say an invoice with plus the local payment IDs --> I need to store the local payment gateway IDs in the same database or even another one.

I programmed everything, but the problem is when the customer hits 'Confirm Order', the store creates the order immediately, but What I need is to create the order in the database after going to index.php?route=checkout/success not after 'Confirm Order'

Seems hard? I payed more than 400$ and no one can do it correctly.

Well for only a few hundred more maybe I can get it right

Sounds like what you think you need is not right either. The order creation isn't something you need to worry about. That is just how opencart works. Sounds like what you need is additional data to be displayed on the success page. I have created customized success pages for payment modules to show more information. PM me what you need to show.

PMed you ;p
