I have a fresh installation for X-cart 4.6.5 and X-Payment 2.11, both residing on the same VPS.

-X-payment test successfully connected to PAYPAL PRO gateway.
-X-cart is configured successfully to connect to X-Payment 2.11.

Here are the bugs I found. See PHP warning at the end. I am using PHP 5.4.34 with Apache/2.2.29

Any idea or tips on this issue? Thank you all in advance.

PROBLEM 1: When I use a discount coupon, per say $40 off. I get the following error:

Reason: Error: Transaction refused because of an invalid argument. See additional error messages for details. (The totals of the cart item amounts do not match order amounts.)



PROBLEM 2: When I don't use a coupon. A regular checkout.

Reason: Error: Invalid Data (Item total is invalid.)

NOTE: Need to update my signature. The last working x-cart store version was 4.54 with X-Payment 1.06.

Please note that X-Payments must be installed separately in order to be PCI compliant. See full PCI DSS guide for X-Cart at http://help.x-cart.com/index.php?title=X-Cart_Payments:PCI_DSS_implementation_guide

With regards to the issues you posted - this needs to be investigated at your server. I suggest you to contact our techs using your HelpDesk account.

We get this same error message and are also using Paypal Pro

Hi guys,

We fixed this issue in our latest update of X-Cart 4 connectors. See http://blog.x-cart.com/xpayments-2-1-3-released.html

Basically you need to install updated X-Payments connector for your X-Cart version.

[Freakmode]

I have already installed that and the issue remains.

After research we've figured what may be a reason for this particular bug.

The issue is caused by rounding at X-Cart side (e.g. when certain tax %% values are configured) and PayPal line items specifics. I.e. X-Cart passes a little bit wrong values to X-Payments, that are then passed to PayPal as line items they require and as result totals do not match at PayPal side and the payment fails.

A solution is not to pass line items to PayPal if totals do not match and we have a patch for X-Payments connector in X-Cart 4.6.5 (xpc_amount_mismatch_wa.diff) for that.
