Paypal Express not showing Shopping Cart Contents in some orders

Hi

I have experienced this problem today. I have tested placing 4-5 orders.
Normally in paypal emails I always receive them in this format :

```


But when I placed another 3 more orders (order with multiple items). one of my paypal email not showing 'paypal shopping cart contents' like in the picture below :

**The 'missing shopping cart content'  happened to both customers's email and the shop owner's email.

But when it appears, it appears in both end too.

**This is a problem because it is a high volume shopping site which means double handling all orders & cross reference everything through the website which just creates more work than is actually necessary.


Paypal Express is the only payment option we have available on the site.

Can some one please suggest why this happen?

Thank you very much in advance.

Regards,

And here is the shop owner's paypal email. (without paypal shopping cart contents)

I believe there is sonething that triggers the cart contents to not be displayes, like c coupon or a Gift certificate or something of the like

Merlin is correct.

DrByte:

Merlin is correct.

There are two active Discount Coupons currently. But I did not use it when I check out. Could this still trigger this problem even if I didn't use it?

The cart-contents can only be sent if the arithmetic is perfect and extremely simple. PayPal's cart-contents-handler cannot handle complex things such as discounts (coupons, gift certificates, group discounts, etc) or tax calculations which round to partial cents.

If any of the arithmetic doesn't "add up" during preparation of the cart contents, only the subtotals will be sent. Otherwise PayPal will give an error to the customer saying "Sorry, invalid parameters sent", and require them to pay using some other method.

When you go shopping at your favorite store, do all your purchase details (each line item) show up on your credit card statement? No. Your "payment-receipt" covers the payment, and your "store-receipt" covers the specific purchase details, including shipping address information as well. It's the same with Zen Cart -- For customer order fulfillment, you should be relying on the data in your Zen Cart admin, not on what's in PayPal.

OK DrBytes, Thank you for your explanation.

I just don't understand why this problem does not happen every time.
Only 1 out of 5 orders that have this problem. And every time I tested order. I did not use discount coupon at all.

I shall explain to the website owner but not sure if he will be happy with this.

Sales Tax

Merlinpa1969:

Sales Tax

What should I do wiht sales tax configuration then Merlin?

Thats the issue,
if sales tax ( using real math ) comes out to xx.75 then your ok but if it comes out to xx.753 then you are not.

When the total is NOT an even number then it has to pass the total as an agregate rather than a line item

there really isnt anything else to do.

Thanks Merlin,

I guess we just have to get on with it for now.:huh:

I don't understand. The products I tested have very simple prices and I didn't use VAT/Delivery charge/discount coupon, so I really can't understand why it's not working.

The shop owner does not accept this and he think this is a 'flackey checkout'.

For him, Paypal does not work because of this problem. I can't use google checkout niether because it does not compatible with Royal Mail yet.

He want the simple process where he just log into paypal and check the order and print off the packing slips from there witout having to login to admin site to search through the website order history to match up which payment goes with which order and record the items sold when he reconciles the bank accounts.

All of their stock / invoicing tools etc are already on a very comprehensive Sage accounts package, so they really don't need the website packing/invoicing admin. They want to avoid having to do everything twice

If I use Nochex instead of paypal, do you think this problem will be resolve?
