Error: 404 API error product with reference [x]

About this article

This article describes error 404, and how to troubleshoot it.

Troubleshooting

When you use ChannelEngine's Merchant API to create shipments on ChannelEngine, you might encounter a 404 error with the message "A product with merchant reference [value] could not be found in order".

{
"StatusCode":404,
"LogId":null,
"Success":false,
"Message":"A product with merchant reference 0 could not be found in order"
} 

This error message means that the shipment exported via the Merchant API contains a shipment line for a product that is unknown to the original order. E.g.:

1. A product with the SKU/Merchant product number '10' is ordered. This value can be found below the GTIN (in this case, the EAN).
   
2. To ship this product, you must include the MerchantProductNo:
   

   { 	  
     "MerchantShipmentNo": "[SHIPMENT NUMBER]",
     "MerchantOrderNo": "[MERCHANT ORDER NUMBER]",
     "Lines": [ 	    
      { 	      
       "MerchantProductNo": "10",
       "Quantity": 1 	    
       } 	  
     ],
     "TrackTraceNo": "[TRACK & TRACE NUMBER]",
     "TrackTraceUrl": "", 	  
     "Method": "[SHIPMENT METHOD]"
   } 	

3. If lines on the shipment contain any other Merchant product number, such as '9' or 't-shirt', it cannot be matched with the original order lines on ChannelEngine and the API returns the 404 error.

To solve this, make sure to ship exactly the same Merchant product number/SKU as was placed in the original order lines.
