As you may aware, the Product Identifier Mandate will be in force starting on June 29.  If the required brand/MPN/GTIN information is not completed for your listings, they cannot be listed/updated.

Related API calls have been updated.  There are several calls developers should understand and use for fulfilling the Product Identifier Mandate.
 

GetCategoryFeatures – http://developer.ebay.com/devzone/xml/docs/Reference/ebay/GetCategoryFeatures.html

Not all categories require brand/MPN/GTIN input.  By making this call on a category, you can find out if they are required.  Please refer to the following attributes of the response:

Category.BrandMPNIdentifierEnabled

Category.UPCEnabled

Category.EANEnabled

Category.ISBNEnabled

 

GeteBayDetails – http://developer.ebay.com/devzone/xml/docs/Reference/ebay/GeteBayDetails.html

If there is no brand, sellers can specify “Unbranded”.  If there is no MPN, sellers can specify “Does not apply”.  “Does not apply” also applies for UPC/EAN/ISBN, but it may vary on different eBay sites.  If <DetailName>ProductDetails</DetailName> is provided in the request when making GeteBayDetails call, the response will return the “Does not apply” equivalent string for no GTIN as follows:

<GeteBayDetailsResponse xmlns="urn:ebay:apis:eBLBaseComponents">

   ..

  <ProductDetails>

      <ProductIdentifierUnavailableText>Does not apply</ProductIdentifierUnavailableText>

   </ProductDetails>

</GeteBayDetailsResponse>
 

AddItem/ReviseItem/RelistItem-family of calls:

When you create or update single-variation listings, you can identify the products using UPC/EAN/ISBN with the ProductListingDetails.EAN, ProductListingDetails.ISBN, or ProductListingDetails.UPC fields.  If using a brand/MPN pair to identify the product, it is advised that you specify this brand/MPN pair through the ProductListingDetails.BrandMPN container AND through two ItemSpecifics.NameValueList containers, as demonstrated below:
<ItemSpecifics>
   <NameValueList>
      <Name>Brand</Name>
      <Value>Somebrand</Value>
   </NameValueList>
   <NameValueList>
      <Name>MPN</Name>
      <Value>A12345</Value>
   </NameValueList>
   ...
</ItemSpecifics>

 

About multi-variation listings:

For multi-variation listings, brand should be specified in item specifics (item-level); MPN can be specified at item-level or variation-level.  GTIN should ONLY be specified at variation-level.  Variation-level can be specified with Variations.Variation.VariationProductListingDetails.UPC (or EAN/ISBN).  However, it is not mandatory to enter product identifier information at this moment, since the mandate will not be in force until September 2015.
