    Id of the member to affect. If omitted, affects the default device in the local client.
  </ParamField>

  <ParamField path="meta" type="Record<string, unknown>">
    The medatada object to assign to the member.
  </ParamField>
</Indent>

#### Returns

`Promise<void>`

#### Permissions

* `room.self.set_meta`: to set the metadata for the local member.
* `room.member.set_meta`: to set the metadata for a remote member.

You need to specify the permissions when [creating the Video Room Token](/docs/apis/video/room-tokens/create-room-token) on the server side.

#### Examples

Setting metadata for the current member:

```js
await roomSession.setMemberMeta({
  meta: {
    email: "joe@example.com",
  },

```js
await roomSession.setMemberMeta({
  memberId: 'de550c0c-3fac-4efd-b06f-b5b8614b8966'  // you can get this from getMembers()
  meta: {
    email: 'joe@example.com'
  }
})
```
