Sample configuration

Following is a sample proxy service that illustrates how to connect to Facebook with the init operation and then use the deletePost operation. The sample request for this proxy can be found in the deletePost sample request . You can use this sample as a template for using other operations in this category.

As a best practice, create a separate sequence for handling the response payload for errors. In the following sample, the sequence that handles errors is faultHandlerSeq.
