10413 , error message Paypal Express

-- HikaShop version -- : 2.3.4
-- Joomla version -- : Joomla 2.5

I have activated the Paypal Express as the only payment solution on my test-site.
I works fine.

When a customer shops for more than 900 NOK he gets free shipping, and the freight displays NOK "0" at the checkout. This is correct.

But when I click on the paypal express button I get the message (see picture below):

Connection failure - error code : 10413 , error message : The totals of the cart item amounts do not match order amounts.

This problem only happends when the freight is NOK 0.

How can I solve this ?

Hello,
Can you test it with the "Send cart detail to paypal" option of your Paypal Express configuration page set to NO ?
Thanks.

Tnx for reply

Update

I have done some more research. The problem is not with free freight. The "10413 , error message" only occur when I buy two or more of an item.

1. So if I buy 1 item of product A it works fine.
2. When I buy 2 or 3 different Items it works fine(only one of each).
But when I buy 2 or more items of product A i get the error message.

....So I turned the "Send cart detail to paypal" function Off, and now it works fine.

But I need this function to be set to on, so that the customer can see the prices in the Paypal checkout.

Any advice ?

OK, tnx for reply. I did as you described. Here is a copy of the Paypel Express log

Hi, and tnx for reply.

OK, I installed the updated plugin, but I still experience the same problem. As I earlier wrote. The error only occur when I add two or more of the same item in the shopping basket.

Here is the debud data after the update.

Tnx Nicolas !

NOW IT WORKS =)

Thank you for excellent service ! =)

OK. I now use the Paypal Express Checkout and it works very well.

There is only one problem.
..."The Payment confirmed" e-mails that I receive from paypal does not include any product name, price or freight price. When I log into my Paypal account It is the same problem, nothing is specified, just the total price.

The information displays just fine when customers used Paypal Standard payment.

I have looked in the Hikashop Changelog, and I find this....
"HikaShop 2.3.4
-The PayPal Express Checkout payment plugin now strips the products description to avoid errors on PayPal's end."

I'm not sure if this has anything to do with it ?

Please see enloused pictures below to see exactly what I mean

NOTE: As you can see I have the "Send cart detail to paypal" set to YES in the Paypal express plugin.

Ok, tnx for reply. But I think you misunderstand me here


Before when I used the normal HikaShop Paypal payment plugin the Payment confirmed e-mails looked like this (Displaying product name, product code, pcs and freight)

Tnx for reply.

Well I did some "Googling", and I seems I am not the only person with this problem. It sees like a very common problem.
Just see this link: stackoverflow.com/questions/7651304/inst...express-checkout-nvp

Seems like it has something to do with the "DoExpressCheckoutPayment" from the Paypal Express Checkout API.
I think the problem lies within your plugin.

...but again, I might be wrong. Any advice

Ok, excellent.

Please post here when the updated plugin is ready and I will also test it.

Many Tnx

I think you should do some research on this. For it does not work at all.

I installed this version on my live site.
...and I had two costumers who made a real purchase, one tried to purchase three time in a row.

Sounds good. Looking forward to get it fixed 100 % =)
