Task Resource
A Task represents a single item of work waiting to be processed. Tasks can represent whatever type of work is important for your team. Twilio applications can create tasks from phone calls or SMS messages. Your CRM or ticketing system can generate tasks from emails or chat messages sent in by your customers. Your own applications can create custom tasks representing whatever unique work your users handle.
Task properties
Pagination is not supported under this resource. Please avoid usage of the page query parameter.
Task Attributes
Every Task has attributes, allowing you to pass along whatever data is required for your application to route the task and take the appropriate action on assignment. Attributes are expressed in JSON data, for example:
{
"type": "call",
"contact": "+15558675309",
"customer-value": "gold",
"task-reason": "support",
"callSid": "CA42ed11..."
}
Task Version
Tasks have a version, represented in the ETag header when you POST or GET the Task Resource. ETags are a method of showing whether a resource has changed; if the ETag is the same, then the resource is the same.
Tasks can also use the If-Match header when updating or deleting a Task Resource. If the ETag does not match the provided version, the operation will fail with a 412 response. You can then GET the latest version of the Task and try updating it again. When the If-Match is not provided, the Task will update without a check.
You can read about Task Mutation and Conflict Resolution to learn about working with Task versions.
Task Lifecycle
A Task does not have an explicit Lifecycle property, but it's an important concept for understanding how Tasks work. A Task's lifecycle is controlled by a Workflow, which will manage the Task's priority and find matching Workers to handle the Task. The Task State page and Workflows and Assignment page provide more detail on the Task lifecycle.
If you wish to update the assignment status of a task to wrapping or completed and also update its attributes, you will need to send two API requests: one for changing the assignment status, and one for updating the attributes.

Example 1
Example 2
Tasks are deleted 5 minutes after either they are canceled or completed. You can still query events that occurred for a Task via the Events API.
You may use the following operators in your EvaluateTaskAttributes:
- Equality:
==,= - Inequality:
!= - Greater than:
> - Less than:
< - Greater than or equal to:
>= - Less than or equal to:
<= - Use parentheses to indicate precedence of operations:
( ) - Use brackets to indicate lists/arrays:
[ ] HAS,>-for determining whether the value of the Task attribute on the left-hand side of the expression contains the string on the right side of the comparison.IN,<-for determining whether the value of the Task attribute on the left-hand side of the expression is * contained in the list on the right-hand side.ANDif both the left and right subexpressions are true, resolves to true, otherwise falseOR- if one or both of the left or right subexpressions are true, resolves to true, otherwise false

sid
Path
|
The SID of the Task resource to update. |

assignment_status
Optional
|
The new status of the task. Can be: |
reason
Optional
|
The reason that the Task was canceled or completed. This parameter is required only if the Task is canceled or completed. Setting this value queues the task for deletion and logs the reason. |
priority
Optional
|
The Task's new priority value. When supplied, the Task takes on the specified priority unless it matches a Workflow Target with a Priority set. Value can be 0 to 2^31^ (2,147,483,647). |

if_match
Header
|
If provided, applies this mutation if (and only if) the ETag header of the Task matches the provided value. This matches the semantics of (and is implemented with) the HTTP If-Match header. |
Example 1
When a pending Task's attributes are updated, the Task will be re-driven through the Workflow identified by the WorkflowSid associated with the task. Depending on the Workflow's filters, TaskRouter may move the Task into a different TaskQueue. The age of the Task will remain the same. If the Task is moved to a new TaskQueue, its TaskQueue position relative to other tasks will be determined by its age and priority, as usual.
Example 2
The previous version of Etag can be found in the client by accessing the following attribute:
client.httpClient.lastResponse.headers.etag
Delete a Task resource
https://taskrouter.twilio.com/v1/Workspaces/{WorkspaceSid}/Tasks/{Sid}
