## What it does

- Changes data in your account. It does not send messages to contacts.
- Acts on a connected outside system.
- Needs a confirmation step (a preview first).
- Safe to repeat with the same Idempotency-Key.

> **Important** Messages are only sent to contacts who may receive them. The server checks the opt-in, never sends to unsubscribed contacts, respects the 24-hour window and uses approved templates only. See [Sending safely](https://docs.smartchat.marketing/en/security/).
