This assumes you have created a RabbitMQ user with the administrator tag.

Refer to the RabbitMQ REST API documentation.

The curl command with the --user option can be used to make an API connection to RabbitMQ. In this example, John Doe will make a connection to the RabbitMQ server listening on port 15671. Or, the rabbitmqctl list_queues or rabbitmqadmin list queues commands can be used.

curl --user john.doe:itsasecret http://hostname:15671/api/vhosts

Or, you can specify a single virtual host.

curl --user john.doe:itsasecret http://hostname:15671/api/vhosts/foo

For the / vhost, use %2F.

curl --user john.doe:itsasecret http://hostname:15671/api/vhosts/%2F

Something like this should be returned for each virtual host.
