TaskRouter Capability Tokens¶
TaskRouter’s Worker.js library lets you add TaskRouter Worker Activity controls and event notifications to your web applications. Worker.js uses a Websocket connection to TaskRouter to receive realtime notifications of Worker Reservations and Task details, and provides a simple API for modifying a Worker’s current Activity.
Capability is responsible for the creation of these
capability tokens. You’ll need your Twilio AccountSid and AuthToken,
the Sid of the Workspace you want to authorize access to, and the Sid
of the Worker you’re granting authorization for.
require 'twilio-ruby' # Get these values from https://twilio.com/user/account account_sid = "AC123" auth_token = "secret" # Create a Workspace and Worker in the TaskRouter account portal # or through the TaskRouter API worker_sid = "WK789" worker_sid = "WK789" @capability = Twilio::TaskRouter::Capability.new account_sid, auth_token, workspace_sid, worker_sid
By default, the Capability object will allow the Worker.js process to read from and write to the websockets used to communicate events, and also to fetch the list of available activities in the workspace.
There are three additional permissions you can grant using the Capability token, and in most cases you’ll want to allow all of them for your application:
This authorizes requests to retrieve the registered Worker’s attributes from the TaskRouter API.
Worker Activity Update¶
This authorizes updates to the registered Worker’s current Activity.
Task Reservation Update¶
This authorizes updates to a Task’s reservation status.
Generate a Token¶
token = @capability.generate_token
By default, this token will expire in one hour. If you’d like to change the
generate_token() takes an optional
token = @capability.generate_token(600)
This token will now expire in 10 minutes. If you haven’t guessed already,
ttl is expressed in seconds.
