Overview for creating new sender handlers

The SenderFramework can invoke handlers at two stages during the sender processing flow: pre-processing and post-processing. These stages are also referred to as configuration points. Pre-processing covers what occurs before the request document is given to the sender to be sent to its destination and post-processing occurs after the request document has been sent to its destination and the SenderResult object has been created to document the request's status.

WBI-C ships with a number of pre-defined handlers, but users may also develop their own, if they have specific needs not satisfied by the delivered handlers. If a request document comes from a preferred trading partner, for example, a pre-processing handler could determine the partner's status and set the transport headers accordingly. Once the handlers are written and deployed, users will need to configure them using the Console, just as they would with Connect supplied handlers. For further information on this process, see the Hub Configuration Guide.
