Changes the given settings of the automatic AI reply; all other settings stay as they are. Turning it on needs a plan that includes it and lets SmartChat answer your customers on its own; turning it off also cancels replies that are waiting to be sent. Returns all settings.

`PATCH /v1/ai-reply-settings`

| | |
|---|---|
| Permission | `ai:settings` ([all permissions](https://docs.smartchat.marketing/en/api/permissions/)) |
| Risk | Write (no outside effect) |
| Idempotency-Key | Optional ([how it works](https://docs.smartchat.marketing/en/concepts/idempotency/)) |
| Safe to repeat | Safe by nature. With the same Idempotency-Key the first answer comes back. |
| Rate limit class | `write` (120 requests per minute per key) |
| Confirmation | None |
| MCP tool | [`update_ai_reply_settings`](https://docs.smartchat.marketing/en/mcp/tools/update_ai_reply_settings/) |
| Since version | 2026-10-25 |

## What it does

- Changes data in your account. It does not send messages to contacts.
- May start automations of the account, and an automation may send messages. The call itself sends nothing.
- Safe to repeat. With the same Idempotency-Key the first answer comes back.
