Accept and update a TaskRouter task reservation for a Twilio Flex agent via the REST API

Steps

1. When TaskRouter creates a reservation for a task-worker match, receive the assignment callback HTTP request at your server; it contains the WorkspaceSid, TaskSid, ReservationSid, and worker details.
2. To programmatically accept the reservation, send a POST to /v1/Workspaces/{WorkspaceSid}/Tasks/{TaskSid}/Reservations/{ReservationSid} with the body parameter ReservationStatus=accepted.
3. To update task attributes (e.g., add context such as CRM data before the agent sees the task), PATCH the Task resource at /v1/Workspaces/{WorkspaceSid}/Tasks/{TaskSid} with an Attributes JSON string.
4. To reassign or redirect, set ReservationStatus=redirected (voice) or call=conference on the reservation with the appropriate target; for non-voice channels, update the assignment callback response with an appropriate instruction.
5. Handle reservation timeouts by monitoring for the reservation.timeout event in your webhook; when triggered, decide whether to re-queue or escalate.
6. After the interaction is complete, update the task to ReservationStatus=completed or wrapping so TaskRouter transitions it through the end-of-task lifecycle correctly.
