Hi,

In my country there is a payment gateway which should be standard and similar to paypal.

I want to integrate it with ubercart and I'll appreciate if someone can tell me which module is close to what I'm looking for and will be easy to modify.

I rather modify one of the core modules if it is suited.

The checkout process:

1. A button on my website should direct the user to the service "authentication page"
https//www.service.com/PO/POLogin.aspx

with the parameters:
PaId - My business id code
OdId - the current deal id code

example:
https//www.service.com/PO/POLogin.aspx?paId=DMBG-T534-4784AAF&Odid=12345

2. The service will direct the user back to my website to a predefined address

OpDesc - define the requested operation. In this case request for deal info.

example:
http://www.MyShop.co.il/getDetailes.php?PaId=DMBFG-T34-4784-AAF&OdId=123...

3. MyShop should confirm OdId and PaId and reply with an xml:

<?xml version="1.0" encoding="windows-1255"?>

OrderId - MyShop generated order Id
OrderDesc - Text describing the deal
OrderTotal - Total sum
NumMaxPayments - maximum payments
JumpToOnSuccess_URL - A URL page on MYShop
IsTest - Set to 1 for testing

4. The service will replay with something like this:
http://www.MyShop.co.il/confirmation.php?PaId=hjgdk-jhgjjmhn-mnvnmmbvnv&
OdId=12345&OrderId=3443&OpDesc=ReqStatus&Status=success&ReferenceId=12
311142&NumOfPayments=30&CCName=%20&CC4Digs=1234

5. MyShop returns:
<?xml version="1.0" encoding="windows-1255"?>

Thanks
