I try to use the AMQP node to sent some data to my RabbitMQ. But I would need an example. It’s not clear for me how I need to configure the node to sent my payload and headers to my RabbitMQ - I don’t even find the option for payload.
Shouldn’t there be an option for exchange and virtual host? I mean normally I sent a message (payload and headers) to an virtual host > exchange. Is topic == exchange?
About the “payload”. The data which gets send is the input-data of the node.
You will, however, have not much luck with RabbitMQ as mentioned by @leonardlin which created the node here on the pull-request:
https://github.com/n8n-io/n8n/pull/101#issuecomment-549050458
He wrote: “It only works for amqp 1.0. RabbitMQ is famous for staying with amqp 0.9.”
Do sadly not know enough about AMQP and/or RabbitMQ to know if the exchange/virtual-host issue has to do with the version mentioned above or if that feature is simply missing.
RabbitMQ supports AMQP 0-9-1, AMQP 1.0, MQTT and STOMP
AMQP 0-9-1 Protocol Specification — RabbitMQ
RabbitMQ implements AMQP 1.0 via a plugin. However, AMQP 1.0 is a completely different protocol than AMQP 0-9-1 and hence not a suitable replacement for the latter. RabbitMQ will therefore continue to support AMQP 0-9-1 indefinitely.
If I manage to install this plugin I might be able to use this node to talk to RabbitMQ 
I’ve noticed that the AMQP node does not use any client library to talk to AMQP. In this case there is no advantage to use it. Then I will stick with the HTTP API of RabbitMQ: RabbitMQ Management HTTP API
