Consume external web services

You can consume web services by adding new class libraries. In Microsoft Dynamics AX 2012, you could consume web services from X++ code by adding Microsoft Visual Studio projects as a reference and by using Aif::CreateServiceClient. This scenario is supported, but the steps have changed. Application Integration Framework (AIF) is no longer supported.

The following steps show how to consume an external StockQuote service from X++.

Note that the web service URL in this sample is fictional. There is no known web service at http://www.contoso.net/stockquote.asmx. To make this code work you will need to adapt it to your specific web service.

1. Create a new Class Library project in Visual Studio, and name it ExternalServiceLibrary.csproj.

2. In the Visual Studio project, add a service reference to the external web service: http://www.contoso.net/stockquote.asmx.

3. Create a new static class, and wrap the StockQuote service operation as shown in the following example.

   public static string GetQuote(string s)
   {
       var binding = new System.ServiceModel.BasicHttpBinding();
       var endpointAddress = new EndpointAddress("http://www.contoso.net/stockquote.asmx");
       ServiceLibrary.QuoteReference.StockQuoteSoapClient client = new ServiceLibrary.QuoteReference.StockQuoteSoapClient(binding, endpointAddress);
   
       //GetQuote is the operation on the StockQuote service
       return client.GetQuote("MSFT");
   }
   

4. Build the project. The binary ExternalServiceLibrary.dll is created.

5. Create a new Dynamics project in Visual Studio.

6. Add ExternalServiceLibrary.dll as a reference.

7. In the X++ class, you can use the external web services that were referenced in ExternalServiceLibrary.dll.

   public static void main(Args _args)
   {
       info(ServiceLibrary.StockQuoteClass::GetQuote("MSFT"));
   }
