Example

In this example, integrate with DNE's Calculator Web Service and view the new steps created for use in a workflow. 

1. Begin by creating a Reference to the WCF Service in the Decisions Studio.
2. Navigate to the project's Design Folder and, at the bottom of the panel, select DATATYPES/INTEGRATION > Add WCF Service Reference.

   

3. For this example, get the URL of the DNE Calculator Service as shown in-browser below:

   

4. In the Studio, name the service reference in the Add WCF Service Reference menu (in this example "Calculator"), and paste the URL (http://www.dneonline.com/calculator.asmx?wsdl) in the URL field. 
5. Then, pick an Endpoint for the service from the drop down menu.

   

6. Click OK to save the WCF Service Reference.
7. The Studio creates a WCF Service Reference in the External Services Folder.

   

8. In the Designer Folder at the bottom of the panel, click CREATE FLOW.
   
9. Name it (in this case "WCF Calculator Steps") and click OK.

   

10. When the WCF service reference was created in the beginning of this example, the Decisions Engine analyzed this new service method and generated new steps to use.
11. The new steps are now available in the Steps tab on the right under the Integrations > My Integrations > WCF Services > [WCF Service Reference Name] category.
