Hi,

Anyone please provide the procedure to fetch multiple item Lookups using Amazon Advertising API in on ego in C#.

C#

string requeststring = "Service=AWSECommerceService"
+ "&Version=2009-03-31"
+ "&Operation=ItemSearch"
+ "&SearchIndex=Books"
+ "&ResponseGroup=OfferFull"
+ "&Keywords=0781750466,0077354761"
