# POST /agent/v1/voice/schedule-callback

**Resource:** [Voice Agent Toolkit](./agent-toolkit-voice.md)  
**MCP tool:** `voice_toolkit_schedule_callback`  
**Scopes:** `agent_toolkit:use`  
**Write operation:** yes

Voice agent toolkit — schedule an automatic AI callback at the time the caller requested (rings them back from the agent's outbound number). Pass callback_day + callback_time + state; the server resolves the absolute date in the caller's timezone, so never compute a date yourself.

## Parameters

| Name | In | Type | Required | Description |
|------|----|------|----------|-------------|
| `callback_day` | body | string | no | Day to call back: "today", "tomorrow", a weekday, or YYYY-MM-DD. Do NOT compute a date. |
| `callback_time` | body | string | yes | Clock time the caller wants, e.g. "3pm", "2:30pm", "14:00". |
| `state` | body | string | no | Caller state/territory for timezone (e.g. QLD, NSW, VIC). |
| `require_approval` | body | boolean | no | Optional. Set true to route this write into the approval queue for human review instead of executing it immediately (returns 202 + an approval_id). Works even when your key/token has permission to execute directly. |
