Amazon Payments Error


I’m trying to setup Amazon Payments, but I’m getting the following Amazon Payments: Merchant error:

<br />
We're sorry, but we're currently having problems retrieving order details from the merchant, and cannot process your order. Please return to the merchant's website and try placing your order again.<br />

```<br />
<br />
In our [b]Amazon Payments Console[/b] we get the following information about the error:<br />
<br />
<br />
Date:		  Mar 30, 2014 4:38:39 AM PDT											<br />
Client Request:		Date<br />
Severity:			FATAL<br />
Error Type:		   CheckoutCart<br />
Error Code:		   CallbackDeliveryFailure<br />
Error Message:		Merchant Callback Delivery Failed.<br />
Cart Request We Received:<br />
				<br />
{"purchaseContractId":null,"widgetId":null}<br />

```<br />
<br />
Did someone experience the same issue?<br />
Any idea how to solve it?<br />
I wonder if CS-Cart solved the issues they had with Amazon Payments at all, as according to other posts in the forum, it seems that it never worked, or at least for for the last one and a half year!<br />
Is there anyone out there that actually succeeded to make it work ever (with MV >= 3.0.6)?<br />
<br />
We are using MV 4.1.2.<br />
<br />
Appreciate your help!


Its about a year since this post. I am using a new install of 4.2.4. I had no problems with Amazon Payments with 2.2.4.

The first two attempts from customers to use Amazon Payments show the same error in the Amazon error log as in this post. I did update the Pipeline Path that is needed for 4.2.4. Otherwise, its the same setup that I used for years in 2.2.4.

Any update to this post?
