### deleteMeta

* **deleteMeta**(`keys`): `Promise<void>`

Deletes the specified keys from the metadata for this RoomSession.

#### Parameters

<ParamField path="keys" type="string[]" required>
  The keys to remove.
</ParamField>

#### Returns

`Promise<void>`

#### Example

In this example, we set metadata for a room as soon as it starts.
After 5 seconds, we remove the metadata for that room. Once the room's metadata is set or removed,
we log the metadata for that room. This example assumes that there is a [`RoomSession`][roomsession-41]
already active and that members are joining the room.

```js
import { SignalWire } from "@signalwire/realtime-api";

// Initialize the SignalWire client
const client = await SignalWire({ project: "ProjectID Here", token: "Token Here" })

// Access the video client from the main client
const videoClient = client.video;

// Setup listener for when a room starts
await videoClient.listen({
  onRoomStarted: async (roomSession) => {
    console.log("Room started", roomSession.displayName);
    await roomSession.setMeta({
      "foo": "bar",
      "roomName": roomSession.displayName
    });
    let roomMeta = await roomSession.getMeta()
    console.log("Room meta", roomMeta);

    // delete room meta after 5 seconds

    setTimeout(async () => {
      console.log("Deleting room meta");
      await roomSession.deleteMeta(["foo"]);
      roomMeta = await roomSession.getMeta()
      console.log("Room meta", roomMeta);
    }, 5000);

  },
  onRoomEnded: async (roomSession) => {
    console.log("Room ended", roomSession.displayName);
  }
});
```
