变异列表的eBay API EAN

Question

I am using eBay API to revise a product on eBay that has variations of Size and Colour.

I have used the documentation to configure my XML file.

However the request returns below error message:

21919420: For multiple-variation listings, GTIN values are specified at the variation level. Please remove the GTIN value from the listing level and provide a GTIN value for each variation within the listing.

My Code:

<?xml version="1.0" encoding="utf-8"?>
<ReviseFixedPriceItemRequest xmlns="urn:ebay:apis:eBLBaseComponents">
<RequesterCredentials><eBayAuthToken>'.USERTOKEN.'</eBayAuthToken></RequesterCredentials>
<WarningLevel>High</WarningLevel>
<Item>
<ItemID>'.$param['itemID'].'</ItemID>'.$xmlpriceandquantity.'
<Title>'.$itemTitle.'</Title>
<ProductListingDetails> 
<BrandMPN>

Answer 1

You're setting your EAN value on the parent, each individual item / sku will have a unique EAN so it will need setting for each variation instead
