Abstract: A method of processing a transaction message is disclosed. The method includes receiving an incoming raw transport message. The raw transport message is stored in a channel interface database. A raw message identifier is generated. The raw message identifier is determined such that the raw message identifier verifiably identifies the raw message. A communications context identifier is generated. The communications context identifier is determined such that the communications context identifier verifiably identifies the raw message and the channel. The raw message is converted into a transaction message and the transaction message is validated.
