2.6. Routing Key

The Routing Key is a string in the message that is used by the message broker to route the message for delivery. In Red Hat Enterprise Messaging, the message subject is used for routing.

Messages have an internal x-ampq-0.10-routing-key property. However, this is managed by the Qpid Messaging API, and you do not need to manually access or set this property. The exception to this is if you are exchanging messages with another AMQP system. In that case you should understand how the Qpid Messaging API manages this property based on message and sender subject.
