# updateParticipants()

> Modifies multiple participants at once in a Daily call.

`updateParticipants(updates)`

Modifies multiple participants at once. Internally loops over the keys of `updates` and calls [`updateParticipant()`](/reference/react-native/instance-methods/update-participant) for each. Use this instead of calling `updateParticipant()` in a loop — changes are batched together, making updates faster.

## Parameters

<ParamField body="updates" type="{ [sessionId: string]: DailyParticipantUpdateOptions }" required>
  An object whose keys are participant session IDs and whose values are the update options for each participant. See [`updateParticipant()`](/reference/react-native/instance-methods/update-participant) for all available actions.

  Use `'*'` as a key to apply the same update to all current participants at once.
</ParamField>

## Return value

Returns `this` (the `DailyCall` instance) for chaining.

## Examples

```javascript theme={null}
// Mute all participants using '*'
call.updateParticipants({ '*': { setAudio: false } });
```

```javascript theme={null}
// Apply different updates to specific participants
call.updateParticipants({
  'session-id-1': { setAudio: false },
  'session-id-2': { setVideo: false },
});
```
