Amazon Product API wrapper in C#
var awsconfiguration = new AwsConfiguration(awskey, awsSecretKey, destination, apiVersion, associateTag, xmlnamespace);
var amazonapi = new AmazonProductApi(awsconfiguration);
var products = await amazonapi.ItemLookup(productids, "Images,ItemAttributes,Offers");
You can optionally pass a Func<string, Task<XDocument>> to avoid hitting amazon services in unit tests
Func<string, Task<XDocument>> retrievelfunc = (url) => Task.FromResult(XDocument.Load(@"Assets\amazon.xml"));
var products = await amazonapi.ItemLookup(productids, "Images,ItemAttributes,Offers", retrievelfunc);Uses signed request helper from here https://aws.amazon.com/code/Product-Advertising-API/2480
