Q: Which option is best for Informed.co Reference, SKU, or ASIN?
A: Some people prefer to use the ASIN, while others prefer the Reference ID that they enter in Sku Grid (since they're putting their Amazon Seller Sku there) and some people wanted the SKU from the supplier. It really depends on you and how you need that information entered into Informed. If Informed is receiving the data and needs your Amazon Seller Sku and you have the Amazon Seller Sku in your reference id, then you would choose Reference ID. If; however, Informed needs the actual ASIN and not seller Sku from you, then you could choose ASIN.
Note: If you're unsure what Informed needs to see from your feed link, then you would need to contact their support team for best advise there as we just provide the means to get the information from Sku Grid into your account, but we do not know the particular details of the Informed side of things and what they need to see in order to revise your items.
