# useRemoveHost

> Revoke a user's host privileges on an event (host-only)

## Overview

`useRemoveHost` returns a callable that removes a user from an event's `hostIds`. **Host-only.** Rejected with `event/last-host` (409) if the removal would leave the event with no hosts.

## Usage Example

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

function RemoveCoHost({ eventId }: { eventId: string }) {
  const removeHost = useRemoveHost();
  return (
    <button onClick={() => removeHost({ eventId, userId: "usr_cohost" })}>
      Remove co-host
    </button>
  );
}
```

## Parameters

<ParamField path="eventId" type="string" required>The event ID.</ParamField>
<ParamField path="userId" type="string" required>The host to remove.</ParamField>

## Returns

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