Your queue token is the alphanumeric string, visible in the links below. Anyone who has access to it will be able to manipulate your queues. By default, on the public commands page, StreamElements hides the customapi link; but if you want, for extra security, you can also hide the entire command itself.
For each section below, go to your custom commands page and create a new command. Copy and paste each response for the corresponding command.
You can name the command whatever you like (in case you have conflicting command names).
