A system, apparatus, and a method of memorializing an e-business audit trail are described. As a method, if a message is to be sent to a subscriber by a message service and if an administrator is running, the message is stored in a corresponding topic in the administrator. If, however, the administrator is not running, the message is stored by the message service. When response is received, if the administrator is running, the response is stored the topic in the administrator corresponding to the sent message, whereas if the administrator is not running, the response is stored by the message service. An audit trail is memorialized by retrieving the stored sent message and the corresponding response.
