If you want to configure each HTTP message that is sent to the same operation on the import to use a different WebSphere® Transformation Extender map, you must configure the message to use the WebSphere Transformation Extender data binding descriptor.
You can set the WebSphere Transformation Extender data binding descriptor on both the response and request messages for an HTTP import.
Set the data binding descriptor on the response message for an HTTP import when you want to configure the messages individually.
Set the data binding descriptor on the request message using the mediation flow component for an HTTP import when you want to configure the messages individually.
If you do not need to configure messages individually, it is recommended that you use the custom properties within the binding itself to make the association with WebSphere Transformation Extender.
