An alternative (modernized) Amazon MWS client targeting .NET standard. This library was used in a new discontinued project. It may need some work and is currently looking for maintainers.

Getting started

var channel = AmazonMWSChannelFactory.Create(new AmazonMWSClientOptions {
    RegionEndpoint = AmazonMWSDefaultEndpoint.NorthAmerica,
    SellerId = "AIXXXXXXXXX",
    SecretKey = "XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX",
    AWSAccessKeyId = "XXXXXXXXXXXXXXXXXXXX"
});
var client = channel.CreateSellersClient();

var result = await client.ListMarketplaceParticipations();

Or if you prefer to integrate with Dependency injeciton

// In Startup.cs...
public void ConfigureServices(IServiceCollection services)
{
    services.AddMvc();
    services.AddAmazonMWSClients();
    services.Configure<AmazonMWSClientOptions>(Configuration); // default client credentials
}

// In MyController.cs
public class MyController { 

    private readonly IAmazonMWSOrdersClient ordersClient;
    
    public MyController(IAmazonMWSOrdersClient ordersClient) {
        this.ordersClient = ordersClient;
    }

    [HttpGet]
    public async Task<IActionResult> Get(CancellationToken cancellationToken)    {
        var ordersResponse = await ordersClient.ListOrders(new ListOrdersRequest {
            MarketplaceIds = new[] { AmazonMWSDefaultMarketplace.UK },
            CreatedAfter = DateTime.UtcNow.AddMonths(-3)
        }, cancellationToken: cancellationToken);
        ordersResponse.EnsureSuccess();

        return Ok(ordersResponse.Result);
    }
}

Running Samples

All samples require credentials to authenticate against Amazon MWS. The easiest way to get started is by editing the ClientOptions instance found in the top of the sample. Alternatively you can use configure all projects with user secrets:

dotnet user-secrets set RegionEndpoint https://mws-eu.amazonservices.com
dotnet user-secrets set SellerId <your seller id>
dotnet user-secrets set SecretKey <your secret key>
dotnet user-secrets set AWSAccessKeyId <your AWS access key>

User secrets are shared amongst all sample projects
