By default, Novu will show the subscriber preferences cog icon on the notification center component. If you want to hide it, you can use the prop showUserPreferences on the PopoverNotificationCenter component.

Users can enable/disable any active channel in the workflow using subscriber preferences

​
Get subscriber preferences

import { Novu } from "@novu/node";

const novu = new Novu("<NOVU_API_KEY>");

// 111 is subscriberId
await novu.subscribers.getPreference("111");

​
Update subscriber preference for a workflow

import { Novu, ChannelTypeEnum } from "@novu/node";

const novu = new Novu("<NOVU_API_KEY>");

// enable in_app channel
await novu.subscribers.updatePreference("subscriberId", "workflowIdentifier", {
  enabled: true,
  channel: { type: ChannelTypeEnum.IN_APP, enabled: true },
});

// enable email channel
await novu.subscribers.updatePreference("subscriberId", "workflowIdentifier", {
  enabled: true,
  channel: { type: ChannelTypeEnum.EMAIL, enabled: true },
});
