To delete a channel when after you no longer need it, simply issue a DELETE command to that channel.
Delete returns a 202, indicating that the request has been accepted, and will take an indeterminate time to process.
If you re-create a channel before all the data has been deleted, the behavior is undefined.
DELETE http://hub/channel/stumptown
Here’s how you can do this with curl:
curl -i -X DELETE http://hub/channel/stumptown
