Reservation Instance Subresource

TaskRouter creates a Reservation subresource whenever a Task is reserved for a Worker. TaskRouter will provide the details of this Reservation Instance subresource in the Assignment Callback HTTP request it makes to your application server.

You have multiple options for handling a Reservation:

Respond to the Assignment Callback with an Assignment Instruction.
Call the REST API with how to handle it.
Allow your Worker to decide if they can take the Reservation with the Worker JS SDK.

The following details the REST API.

Important: If you do not respond with how to handle your Reservation within the TaskReservationTimeout configured on a Workflow, then the Reservation will timeout and the Task will be available for other workers.

Resource Properties

A Reservation has the following properties.

Field	Description
Sid	The unique ID of this Reservation.
AccountSid	The ID of the Account that owns this Task
WorkspaceSid	The ID of the Workspace that this task is contained within.
TaskSid	The ID of the reserved Task
WorkerSid	The ID of the reserved Worker
WorkerName	Human readable description of the Worker that is reserved
ReservationStatus	The current status of the reservation. See the table below for possible values.

Possible values for ReservationStatus:

Status	Description
accepted	The Reservation was accepted by the Worker.
canceled	The Reservation was canceled because the reservation timeout was reached.
completed	The Reservation was marked as completed.
pending	A Worker has been reserved for this task and TaskRouter is waiting on a reservation response.
rejected	The Reservation was rejected by the Worker.
rescinded	The Reservation was removed from the Worker.
timeout	The Reservation timed out waiting for a response. When this happens, the Task will remain in the queue and TaskRouter will attempt to assign the Task to the next eligible Worker.
wrapping	The Worker has finished the primary work and is finishing additional duties for the Reservation.

Update Reservation

Resource URI

1POST /v1/Workspaces/{WorkspaceSid}/Tasks/{TaskSid}/Reservations/{ReservationSid}
2

To indicate that a Worker has accepted or rejected a Reservation, you make an HTTP POST request to a Reservation instance resource URI.

You can issue a simple Accept or Reject request. You can also issue an Instruction, similar to Responding to an Assignment Callback. We'll detail what parameters need to be provided for each method:

Accept a Reservation

Accepting a reservation means that the worker will work on the task, but you will need to do whatever work is required to connect the details of that task to the worker. You can think of accept as the bare minimum option for task acceptance. For voice tasks, the other methods described below are supersets of accept.

Example

Accept a Reservation

1// Download the helper library from https://www.twilio.com/docs/node/install
2const twilio = require("twilio"); // Or, for ESM: import twilio from "twilio";
3
4// Find your Account SID and Auth Token at twilio.com/console
5// and set the environment variables. See http://twil.io/secure
6const accountSid = process.env.TWILIO_ACCOUNT_SID;
7const authToken = process.env.TWILIO_AUTH_TOKEN;
8const client = twilio(accountSid, authToken);

POST Parameters

Field	Required?	Description
ReservationStatus	Yes	`rejected`. Specifying rejected means the Worker has refused the assignment and TaskRouter will attempt to assign this Task to the next eligible Worker. (🏢 not PII )
WorkerActivitySid	No	If rejecting a reservation, change the worker that is tied to this reservation to the supplied activity. If not provided, the WorkerPreviousActivitySid on the Reservation will be used. (🏢 not PII )

Note: Tasks are automatically canceled after 1,000 rejections.

Although Tasks have always been cancelled after 1,000 rejections, the documentation previously incorrectly showed that Tasks are automatically cancelled after 10 rejections. If your solution requires Tasks to be cancelled after 10 rejections instead, please contact our support team for help.

Refer to Manually accepting or rejecting a reservation for more information.

Conference Instruction

(information)

Info

Conference instruction is the recommended way to connect calls between customer and agents. This should be used in almost all cases instead of dequeue or call for call center scenarios

Conference instruction takes care of a lot of the call orchestration which you would otherwise do yourself. For a given call represented by a task in TaskRouter, issuing a conference instruction will:

Call the worker on either the specified contact_uri of the worker, or the provided to field
Monitor call status to check that the agent has answered the call
Put the agent call into a Conference, named by TaskSid
Monitor that the above has succeeded
Move the caller out of the queue and into the conference
Mark the task as accepted if and only if all the above succeeded, and handle corner cases (such as caller hangs up during this process) gracefully.

Note that conference instruction works out of the box with calls that have been in TaskRouter using the native TaskRouter integration. If you are creating the task manually for a voice call, in order to use conference instruction you must at minimum include in the Task Attributes {"call_sid" : "<callsid>", "to" : "<E.164 to number>"}

POST Parameters

Conference instruction uses the Conference Participants API. All values valid for that API can be provided as part of the conference instruction. Note that those parameter names are not replicated here. Please refer to linked documentation for valid values.

Note that the Participant API parameters provided apply to the worker leg of the call, not the customer leg of the call. In particular, note that endConferenceOnExit can only be set for the worker leg. If the customer hangs up if you want the agent call leg to be torn down you should do that via API.

Field	Required?	Description
Instruction	Yes	`Conference` (🏢 not PII )
To	No	The contact URI of the Worker. A phone number or client ID. Must be a string. Required if the worker's attributes do not include a `contact_uri` property. (📇 PII )
From	No	The caller ID for the call to the worker. Must be a string. Note: This needs to be a verified Twilio number. If you need this to be the original caller number, please contact Support (📇 PII )
PostWorkActivitySid	No	(Deprecated) The activity to move a worker to after executing a conference instruction. Not valid in multi-tasking workspaces. (🏢 not PII )
Timeout	No	The integer number of seconds that Twilio should allow the phone associated with `contact_uri` to ring before assuming there is no answer. Default is 60 seconds, the maximum is 999 seconds. Note, you could set this to a low value, such as 15, to hang up before reaching an answering machine or voicemail. (🏢 not PII )
All other Participant API possible parameters except for the following: `caller-id` `byoc` `recording-track` `label` `recording-status-callback-event` `conference-recording-status-callback-event` `coaching` `call-sid-to-coach` `call-reason` `speaker`	No	See linked documentation

Note: A property of contact_uri is required on the WorkerAttributes to indicate whom to call. See more information on this here.

POST Parameters

Field	Required?	Description
Instruction	Yes	`Dequeue` (🏢 not PII )
DequeueTo	No	The contact URI of the Worker. A phone number or client ID. Required if the worker's attributes do not include a `contact_uri` property. (📇 PII )
DequeueFrom	Yes	The caller ID for the call to the worker. Note: This needs to be a verified Twilio number. If you need this to be the original callee number, please contact Support (📇 PII )
DequeuePostWorkActivitySid	No	The activity to move a worker to after executing a dequeue instruction. (🏢 not PII )
DequeueRecord	No	The 'DequeueRecord' attribute lets you record both legs of a call. Set to "record-from-answer" to record the call from answer. Default to "do-not-record" which will not record the call. The RecordingUrl will be sent with DequeueStatusCallbackUrl. (🏢 not PII )
DequeueTimeout	No	The integer number of seconds that Twilio should allow the phone associated with `contact_uri` to ring before assuming there is no answer. Default is 60 seconds, the maximum is 999 seconds. Note, you could set this to a low value, such as 15, to hangup before reaching an answering machine or voicemail. (🏢 not PII )
DequeueStatusCallbackUrl	No	A URL that Twilio will send asynchronous webhook requests to on completed call event. **Note: TaskRouter sends "taskCallSid" as parameter with sid of the call that created the Task. This is very useful in the event a call to worker fails, where you could remove the original call from queue and send to voice mail or enqueue again with new workflow to route to different group of workers. (🏢 not PII )
DequeueStatusCallbackEvent	No	The call progress events that will be sent via webhooks on a worker's call. Available values are initiated, ringing, answered, and completed. If you want to receive multiple events, please provide multiple DequeueStatusCallbackEvent values as individual parameters in the `POST` request. If no event is specified, defaults to completed. For example to receive webhooks on answered and completed events pass "DequeueStatusCallbackEvent=answered&DequeueStatusCallbackEvent=completed". Please click here for more details. (🏢 not PII )

Note: A property of contact_uri is required on the WorkerAttributes to indicate whom to call. See more information on this here.
