# NOTIFY

> **Implementation: experimental · Proposal: [in-review](https://github.com/napplet/naps/pull/11)** (status checked 2026-10-31). Notification binding ships with limited dedicated domain regression evidence; broader host integration confidence is unverified. All capabilities remain subject to change. [Maturity and opt-in policy](https://napplet.run/docs/naps/maturity.md).

Shell-rendered notifications, badges, and interaction callbacks.

```ts
const { notificationId } = await window.napplet.notify.send({ title: 'New message', body: 'Alice: hey!' });
window.napplet.notify.badge(3);
window.napplet.notify.onAction((id, actionId) => { if (actionId === 'reply') openReply(id); });
```

This non-normative guide defers to the living [NAP-NOTIFY proposal](https://github.com/napplet/naps/pull/11). Feature-gate with `if (window.napplet?.notify)` before use; the runtime injects only available domains. Typed helpers ship from [`@napplet/nap/notify`](https://napplet.run/docs/packages/nap.md) and [`@napplet/sdk`](https://napplet.run/docs/packages/sdk.md).
