# useAddInvite

> Invite a user to an event (host-only)

## Overview

`useAddInvite` returns a callable that invites a user to an event. **Host-only.** Idempotent against the unique `(eventId, userId)` constraint. For an `invite`-visibility event, the invited user can now see and RSVP to it; when the `notifications` bundle is enabled, the invitee receives an `event-invite` notification.

## Usage Example

```tsx theme={null}
import { useAddInvite } from "@sublay/react-js";

function InviteButton({ eventId }: { eventId: string }) {
  const addInvite = useAddInvite();
  return (
    <button onClick={() => addInvite({ eventId, userId: "usr_guest" })}>
      Invite
    </button>
  );
}
```

## Parameters

<ParamField path="eventId" type="string" required>The event ID.</ParamField>
<ParamField path="userId" type="string" required>The user to invite (userId only — never a foreign ID).</ParamField>

## Returns

Returns a `Promise<Event>` — the updated [Event](/data-models/event).
