Update Call Task
Reschedules a call task and/or sets custom field values on the customer interaction created for its call.
A new requested_at is put through the agent’s calling hours again, exactly as on creation, so the resulting scheduled_at may be later than the time you asked for. Only a task with the scheduled status can be rescheduled; a task whose call is already under way or that has reached a terminal status is rejected with a 409 Conflict response.
Authorizations

Path Parameters
ID of the call task
Body
The earliest time the call may be placed. Accepts ISO 8601 format with a timezone offset (e.g. '2026-08-03T14:30:00Z' or '2026-08-03T09:30:00-05:00'). A time in the past means as soon as the agent's calling hours allow. May be at most 90 days in the future.
The time past which the call is no longer worth placing, for example because the appointment it is about has happened. If no call can be placed before it, the task fails instead of calling late. Defaults to five days after requested_at, and must be after it.
Custom fields to set on the customer interaction created for this call. Each key must match the field_name of a Customer interaction custom field defined in your Alpharun dashboard; entries whose keys don't match a definition are ignored.
