You should be able to call pn_messenger_accept(...) or
messenger.accpet(...) on the tracker of the message depending on what
flavor of the API you are using. In python, the tracker is returned when
you call get(...) in C you can access the tracker for the most recently
received message by using pn_messenger_incoming_tracker(...).
