### updateMemberMeta

* **updateMemberMeta**(`params`): `Promise<void>`

Updates a member's metadata in only the specified fields. This is different from
[setMemberMeta][link-3], which replaces the whole metadata object.

#### Parameters

| Name               | Type                        | Description                                                         |
| :----------------- | :-------------------------- | :------------------------------------------------------------------ |
| `params`           | `Object`                    | -                                                                   |
| `params.memberId?` | `string`                    | Id of the member to affect. If omitted, affects the current member. |
| `params.meta`      | `Record``<string, unknown>` | The update to the metadata.                                         |

#### Returns

`Promise<void>`

#### Example

```js
roomSession.on("member.updated", (e) => {
  // We can set an event listener to log changes to the metadata.
  console.log(e.member.meta);
});

await roomSession.setMemberMeta({
  memberId: "...",
  meta: { foo: "bar", baz: true },
});
// The logger will now print `{ foo: "bar", baz: true }`

await roomSession.updateMemberMeta({
  memberId: "...",
  meta: { baz: false, t: 10 },
});
// The logger will now print `{ foo: "bar", baz: false, t: 10 }`
```
