Amazon Error 8560: Creation of a new ASIN requires...
The error messages returned by Amazon can often be confusing, at times even misleading.
A perfect example is the Error 8560 which looks like this:
SKU #######, Missing Attributes standard_product_id,missing_keyset_reason. SKU ####### does not match any ASIN. Creation of a new ASIN requires the following missing attributes: standard_product_id,missing_keyset_reason. Feed ID: 0. For details, see http://sellercentral.amazon.co.uk/gp/errorcode/2006923707
At first, it looks like your feed would be missing some required data - but there are no columns called
standard_product_id or
missing_keyset_reason in any product feed. In fact, what Amazon means is the external_product_id field, which is where your UPC or EAN should be when you create new products on Amazon.
Assuming that you did enter a UPC or EAN and it does actually show in the external_product_id column in your feed, this message is Amazon's way of telling you that
your EAN or UPC
is incorrect.
So if you see this error, please double check your UPC / EAN and correct any invalid numbers. There are plenty of UPC and EAN validators online which will tell you right away if your number is valid or not.
