4.10.5. Publish to a Headers Exchange

To publish to a headers exchange, pass the name of the exchange to the sender constructor, and add the header keys and value to the message properties. For example:
Python
import sys
from qpid.messaging import *
conn =  Connection("localhost:5672")
conn.open()
try:
  ssn = conn.session()
  txheaders = ssn.sender("amq.match")
  msg = Message("Headers Exchange message")
  msg.properties['header1'] = 'value1'
  txheaders.send(msg)
finally:
  ssn.close()
