Processing bulk operation requests

Describes how to process operations in bulk by using the ASINList, SellerSKUList, and IdList request parameters.

Operations in the Amazon MWS Products API section that take an ASINList, SellerSKUList, or IdList as input parameters can return the results from each of these inputs separately from all the other inputs. This means that if you specify 20 ASINs with the ASINList input parameter of the GetCompetitivePricingForASIN operation, for example, and the operation can only get data for 18 of these ASINs, the operation will return results for the 18 ASINs instead of failing the entire request. The operation will also indicate that the remaining two ASINs failed. The seven bulk operations that take either an ASINList, SellerSKUList, or IdList as input parameters are: GetMatchingProduct, GetMatchingProductForId, GetCompetitivePricingForSKU, GetCompetitivePricingForASIN, GetLowestOfferListingsForSKU, GetLowestOfferListingsForASIN, and GetMyFeesEstimate.

The following example shows how to use the ASINList input parameter to specify three ASINs in a query request:

?AWSAccessKeyId=AKIAJGUVGFGHNKE2NVUA
&Action=GetMatchingProduct
&MWSAuthToken=amzn.mws.4ea38b7b-f563-7709-4bae-87aeaEXAMPLE
&SellerId=A2NK2PX936TF53

&Timestamp=2012-02-07T01%3A22%3A39Z
&Version=2011-10-01
&Signature=MhSREjubAxTGSldGGWROxk4qvi3sawX1inVGF%2FepJOI%3D
&SignatureMethod=HmacSHA256
&MarketplaceId=ATVPDKIKX0DER
&ASINList.ASIN.1=B002KT3XRQ
&ASINList.ASIN.2=B002KT3XQC
&ASINList.ASIN.3=B002KT3XQM

A query request using the SellerSKU input parameter would be formed similarly, replacing &ASINList.ASIN with &SellerSKUList.SellerSKU and ASIN values with SellerSKU values. Likewise, a query request using the Id input parameter would be formed similarly, replacing &ASINList.ASIN with &IdList.Id and ASIN values with Id values.

Bulk operations in the Amazon MWS Products API section return an OperationNameResult response element for each product identifier (ASIN, SellerSKU, or Id) that is specified in the request. Each OperationNameResult response element contains a Status attribute that indicates whether or not data could be returned for the specified product identifier, and an ASIN, SellerSKU, or Id attribute that indicates the ASIN, SellerSKU, or Id value that was specified in the request.

The following table shows response elements that are returned by bulk operations in the Amazon MWS Products API section. Note that you can find examples of these response elements in the appropriate Example response sections throughout this document.
