Thread: Need help customizing for Level 3 gateway

Our client's storefront (version 8.2) does Business-to-Government sales, which qualifies them to do Level 3 payment processing to greatly reduce processing costs. For Level 3 processing, we need to provide to the gateway (3Delta Systems) descriptive line item detail about the products sold such as Product Part Number, Product Description, Quantity, Unit of Measure and Price.

Before we purchase the source code to set up the site to handle Level 3 processing, we'd appreciate hearing from those who have done gateway modifications with ideas of how best to implement this, and alerts to any possible landmines. We've done a bunch of other site customizations (without source code), so we assume this customization should be fairly straightforward, but would like some confirmation before investing in the source code.

Thanks.

That would definitely be possible, but it's going to take some changes in several spots throughout the gateway/payment handling logic. Gateway classes currently don't have access to that level of order detail (just things like ordertotal, shipping address, etc) so you'd have to make some modifications to pass all of that along to where you want to reference it.

Thanks Scott. I assume that means none of the existing gateway classes supports Level III. At least it's good to know in advance that it's possible. Do you know if I'll be modifying just c# code, or if I'll need to play with some XSLT as well?

Once we get the source code, I may be back on the forum for help with getting all the information to the gateway class.

In v8, I'd probably take an existing gateway such as SagePay/Protx (Protx.cs) as a template guide.

You should be able to get all of your level III info in C# alone. Then you could create a call from the Gateway.cs code to pass in the cart info and use SQL to extract the order line items.

Adam, that's just the info I need. Thanks. I'm a C# guy. Whenever I need to play with the XSLT it's a struggle since I don't do enough of it to absorb the syntax.

Purchased the source code. Is there a reason I cannot easily retrieve the shopping cart information I need from within the gateway class code to get line item data with the following code (which I found in the GoogleCheckout.cs file)?

Code:

ThisCustomer = new Customer(CustomerID, true);
ShoppingCart cart = new ShoppingCart(1, ThisCustomer, CartTypeEnum.ShoppingCart, 0, false);

And then just loop thru it with

foreach (CartItem ci in cart.CartItems) { }

Never mind. Dug thru the code and figured out I can send the cart to my custom gateway class from Gateway.cs.
