If the queue id is not there you can use the JavaScript ID to get a list of the queues (or look up by the name) and then retrieve the queue id from the returned results.

Sorry, I tried to answer your question in between meetings, and my answer was garbled.
Take a look at this API. There is a query parameter to filter the results by name. You can use our API explorer or CLI to poke at this endpoint to understand the shape of the data. So if you need the queue ID for a specific queue name you can use this API. You can also use our Javascript API (though in the context of a web client, the SDK is a very light wrapper around the API and most Dev's call the API directly.
I hope that helps.
