# Publish with AMQP Sender in Duaer

In Duaer, AMQP Sender publishes over AMQP 1.0 to a Queue / Topic once per item. You need an amqp credential.
## Send a message

1. Create an amqp credential.
2. Search for AMQP Sender, connect it after the previous node, and select that credential.
3. Set Queue / Topic to the queue or topic name.
4. Optionally set Headers as JSON. Under Options, Data as Object defaults to off; Reconnect defaults to on.
5. Select Execute step.

With Send Property empty, the whole item is sent. Set it to send only that field.

To receive messages, use AMQP Trigger with the same Queue / Topic field.
## Questions

### Does AMQP Sender in Duaer consume from the queue?
