Preferences, Templates & Sounds

Common Preferences

Login to CometChat dashboard and navigate to the Notifications section. Under Preferences tab, set the event preferences at the CometChat app-level and decide if users have the capability to override these settings. When “Override” toggle is enabled, users will have the capability to modify the default value that has been set.

Group preferences

Dashboard configuration

As the name suggests, these preferences help you to configure Notifications for events generated in group conversations.

Categories	Events	Available preferences	Can user override?
Conversations	New messages	• Don’t notify • Notify for all messages (Default) • Notify for messages with mentions	• Yes (Default) • No
	New replies	• Don’t notify • Notify for all replies (Default) • Notify for replies with mentions	• Yes (Default) • No
Message actions	Message is edited	• Don’t notify • Notify (Default)	• Yes • No (Default)
	Message is deleted	• Don’t notify • Notify (Default)	• Yes • No (Default)
	Message receives a reaction	• Don’t notify • Notify for reactions received on all messages • Notify for reactions received on own messages (Default)	• Yes (Default) • No
Group actions	A member leaves	• Don’t notify (Default) • Notify	• Yes (Default) • No
	A new member is added	• Don’t notify (Default) • Notify	• Yes (Default) • No
	A new member joins	• Don’t notify (Default) • Notify	• Yes (Default) • No
	A member is kicked	• Don’t notify (Default) • Notify	• Yes (Default) • No
	A member is banned	• Don’t notify (Default) • Notify	• Yes (Default) • No
	A member is unbanned	• Don’t notify (Default) • Notify	• Yes (Default) • No
	A member’s scope changes	• Don’t notify (Default) • Notify	• Yes (Default) • No

Regarding Message edited & Message deleted eventsPush notifications should be triggered for the message edited and message deleted events in order to retract the notification displaying the original message. Turning them off is not recommended.

Client-side implementation

1. Fetch group preferences CometChatNotifications.fetchPreferences() method retrieves the notification preferences as an instance of NotificationPreferences class. If the user has not configured any preferences, the default preferences defined by the CometChat administrator via the dashboard will be returned.

JavaScript

iOS
Flutter

// This is applicable for web, React native, Ionic cordova
const preferences = await CometChatNotifications.fetchPreferences();

// Display Group preferences
const groupPreferences = preferences.getGroupPreferences();

const groupMessagesPreference = groupPreferences.getMessagesPreference();
const groupRepliesPreference = groupPreferences.getRepliesPreference();
const groupReactionsPreference = groupPreferences.getReactionsPreference();
const memberLeftPreference = groupPreferences.getMemberLeftPreference();
const memberAddedPreference = groupPreferences.getMemberAddedPreference();
const memberJoinedPreference = groupPreferences.getMemberJoinedPreference();
const memberKickedPreference = groupPreferences.getMemberKickedPreference();
const memberBannedPreference = groupPreferences.getMemberBannedPreference();
const memberUnbannedPreference = groupPreferences.getMemberUnbannedPreference();
const memberScopeChangedPreference =
  groupPreferences.getMemberScopeChangedPreference();

CometChatNotifications.fetchPreferences(new CometChat.CallbackListener<NotificationPreferences>() {
  @Override
  public void onSuccess(NotificationPreferences notificationPreferences) {
      // Display group preferences
      GroupPreferences groupPreferences = notificationPreferences.getGroupPreferences();

      MessagesOptions groupMessagesPreference = groupPreferences.getMessagesPreference();
      RepliesOptions groupRepliesPreference = groupPreferences.getRepliesPreference();
      ReactionsOptions groupReactionsPreference = groupPreferences.getReactionsPreference();
      MemberActionsOptions memberAddedPreference = groupPreferences.getMemberAddedPreference();
      MemberActionsOptions memberLeftPreference = groupPreferences.getMemberLeftPreference();
      MemberActionsOptions memberJoinedPreference = groupPreferences.getMemberJoinedPreference();
      MemberActionsOptions memberKickedPreference = groupPreferences.getMemberKickedPreference();
      MemberActionsOptions memberBannedPreference = groupPreferences.getMemberBannedPreference();
      MemberActionsOptions memberUnbannedPreference = groupPreferences.getMemberUnbannedPreference();
      MemberActionsOptions memberScopeChangedPreference = groupPreferences.getMemberScopeChangedPreference();
  }

  @Override
  public void onError(CometChatException e) {
      // Something went wrong while fetching notification preferences
  }
});

CometChatNotifications.fetchPreferences { notificationPreferences in
  // Display group preferences
  let groupPreferences = notificationPreferences.groupPreferences;

  let groupMessages = groupPreferences?.messagesPreference;
  let groupReplies = groupPreferences?.repliesPreference;
  let groupReactions = groupPreferences?.reactionsPreference;
  let left = groupPreferences?.memberLeftPreference;
  let added = groupPreferences?.memberAddedPreference;
  let joined = groupPreferences?.memberJoinedPreference;
  let kicked = groupPreferences?.memberKickedPreference;
  let banned = groupPreferences?.memberBannedPreference;
  let unbanned = groupPreferences?.memberUnbannedPreference;
  let scope = groupPreferences?.memberScopeChangedPreference;

} onError: { error in
  // Something went wrong while fetching notification preferences.
  print("fetchPreferences: \(error.errorCode) \(error.errorDescription)");
}

CometChatNotifications.fetchPreferences(
    onSuccess: (notificationPreferences) {
      // Display group preferences
      GroupPreferences? groupPreferences = notificationPreferences.groupPreferences;

      MessagesOptions? messagesPreference = groupPreferences?.messages;
      RepliesOptions? repliesPreference = groupPreferences?.replies;
      ReactionsOptions? reactionsPreference = groupPreferences?.reactions;
      MemberActionsOptions? memberAddedPreference = groupPreferences?.memberAdded;
      MemberActionsOptions? memberJoinedPreference = groupPreferences?.memberJoined;
      MemberActionsOptions? memberLeftPreference = groupPreferences?.memberLeft;
      MemberActionsOptions? memberKickedPreference = groupPreferences?.memberKicked;
      MemberActionsOptions? memberBannedPreference = groupPreferences?.memberBanned;

    },
    onError: (e) {
      debugPrint("fetchPreferences:error ${e.toString()}");
    });

2. Update group preferences CometChatNotifications.updatePreferences() method is used to update a user’s notification preferences. The “override” toggle defined in the dashboard is crucial when updating preferences. If any preference is non-overridable, the method doesn’t generate an error; it instead returns the NotificationPreferences object with the updated values where overrides are allowed. This functionality can be beneficial for temporarily superseding certain user preferences to ensure notifications for a specific event are delivered. Nonetheless, it is advisable to use this approach temporarily to avoid confusing users with unexpected changes to their notification settings. It is unnecessary to specify all values; only set and save the preferences that have been changed.

Since the user is performing this action, enums have values as SUBSCRIBE or DONT_SUBSCRIBE. It is equivalent to “Notify” and “Don’t notify” respectively, from the dashboard preferences.

Mute preferences

Dashboard configuration

These preferences allow you to control whether the users will be able to modify mute preferences.

Mute preferences	Can user configure?
Mute all notifications (DND)	• Yes (Default) - Users can activate the Do Not Disturb (DND) feature. • No
Mute group conversations	• Yes (Default) - Users can mute notifications for chosen group conversations for a specified duration. • No
Mute one-on-one conversations	• Yes (Default) - Users can mute notifications for chosen one-on-one conversations for a specified duration. • No

Nonetheless, it is advisable to use this approach temporarily to avoid confusing users with unexpected changes to their notification settings. It is unnecessary to specify all values; only set and save the preferences that have been changed. To mute one or more group or one-on-one conversations, utilize the CometChatNotifications.muteConversations() method. This method requires an array of MutedConversation objects, each containing the following properties:

Property	Type	Description
`id`	String	This can either be `uid` or `guid`.
`type`	String	This can either be `oneOnOne` or `group`.
`until`	Number	This is a valid timestamp from the future. Eg: 1710696964705.

To unmute one or more group or one-on-one conversations that were muted by the user, utilize the CometChatNotifications.unmuteConversations() method. This method requires an array of UnmutedConversation objects, each containing the following properties:

Property	Type	Description
`id`	String	This can either be `uid` or `guid`.
`type`	String	This can either be `oneOnOne` or `group`.

Notification schedule

Dashboard configuration

Notifications will be delivered based on the specified daily timetable, adhering to the user’s local time zone. Select “None” to disable Notifications for that day. For instance, this can be applied to weekends, such as Saturday and Sunday.

Day	From	To	Can user override?
Monday	• 0 to 2359 (Default: 0) • None	• Upto 2359 (Default: 2359)	• Yes (Default) - Users can configure a personalized notification schedule. • No
Tuesday	• 0 to 2359 (Default: 0) • None	• Upto 2359 (Default: 2359)
Wednesday	• 0 to 2359 (Default: 0) • None	• Upto 2359 (Default: 2359)
Thursday	• 0 to 2359 (Default: 0) • None	• Upto 2359 (Default: 2359)
Friday	• 0 to 2359 (Default: 0) • None	• Upto 2359 (Default: 2359)
Saturday	• 0 to 2359 (Default: 0) • None	• Upto 2359 (Default: 2359)
Sunday	• 0 to 2359 (Default: 0) • None	• Upto 2359 (Default: 2359)

Client-side implementation

1. Fetch schedule preferences CometChatNotifications.fetchPreferences() method retrieves the notification preferences saved by the user as an instance of NotificationPreferences class. If the user has not configured any preferences, the default preferences defined by the CometChat administrator via the dashboard will be utilized.

JavaScript
Android
iOS
Flutter

// This is applicable for web, React native, Ionic cordova
const preferences = await CometChatNotifications.fetchPreferences();

// Display schedule preferences
const mutePreferences = preferences.getMutePreferences();
const schedulePreference = mutePreferences.getSchedulePreference();

const mondaySchedule = schedulePreference.get(DayOfWeek.MONDAY);
const tuesdaySchedule = schedulePreference.get(DayOfWeek.TUESDAY);
const wednesdaySchedule = schedulePreference.get(DayOfWeek.WEDNESDAY);
const thursdaySchedule = schedulePreference.get(DayOfWeek.THURSDAY);
const fridaySchedule = schedulePreference.get(DayOfWeek.FRIDAY);
const saturdaySchedule = schedulePreference.get(DayOfWeek.SATURDAY);
const sundaySchedule = schedulePreference.get(DayOfWeek.SUNDAY);

// This action can be performed on other days of the week.
const mondayFrom = mondaySchedule?.getFrom();
const mondayTo = mondaySchedule?.getTo();
const mondayDnd = mondaySchedule?.getDND();

CometChatNotifications.fetchPreferences(new CometChat.CallbackListener<NotificationPreferences>() {
  @Override
  public void onSuccess(NotificationPreferences notificationPreferences) {
      // Display schedule preferences
      MutePreferences mutePreferences = notificationPreferences.getMutePreferences();
      Map<DayOfWeek, DaySchedule> scheduleMap = mutePreferences.getSchedulePreference();

      DaySchedule monday = scheduleMap.get(DayOfWeek.MONDAY);
      DaySchedule tuesday = scheduleMap.get(DayOfWeek.TUESDAY);
      DaySchedule wednesday = scheduleMap.get(DayOfWeek.WEDNESDAY);
      DaySchedule thrusday = scheduleMap.get(DayOfWeek.THURSDAY);
      DaySchedule friday = scheduleMap.get(DayOfWeek.FRIDAY);
      DaySchedule saturday = scheduleMap.get(DayOfWeek.SATURDAY);
      DaySchedule sunday = scheduleMap.get(DayOfWeek.SUNDAY);

      // This action can be performed on other days of the week.
      int mondayFrom = monday.getFrom();
      int mondayTo = monday.getTo();
      boolean mondayDnd = monday.getDnd();
  }

  @Override
  public void onError(CometChatException e) {
      // Something went wrong while fetching notification preferences
  }
});

CometChatNotifications.fetchPreferences { notificationPreferences in
  // Display schedule preferences
  let mutePreferences = notificationPreferences.mutePreferences;

  let schedulePref = mutePreferences?.schedulePreference;

  let mondaySchedule = schedulePref?[.MONDAY];
  let tuesdaySchedule = schedulePref?[.TUESDAY];
  let wednesdaySchedule = schedulePref?[.WEDNESDAY];
  let thursdaySchedule = schedulePref?[.THURSDAY];
  let fridaySchedule = schedulePref?[.FRIDAY];
  let saturdaySchedule = schedulePref?[.SATURDAY];
  let sundaySchedule = schedulePref?[.SUNDAY];


  // This action can be performed on other days of the week.
  let mondayFrom = mondaySchedule?.from;
  let mondayTo = mondaySchedule?.to;
  let mondayDND = mondaySchedule?.dnd;
} onError: { error in
  // Something went wrong while fetching notification preferences.
  print("fetchPreferences: \(error.errorCode) \(error.errorDescription)");
}

CometChatNotifications.fetchPreferences(
      // Display schedule preferences
      MutePreferences? mutePreferences = notificationPreferences.mutePreferences;
      Map<DayOfWeek, DaySchedule>? scheduleMap = mutePreferences?.schedule;

      DaySchedule? mondaySchedule = scheduleMap?[DayOfWeek.MONDAY];
      DaySchedule? tuesdaySchedule = scheduleMap?[DayOfWeek.TUESDAY];
      DaySchedule? wednesdaySchedule = scheduleMap?[DayOfWeek.WEDNESDAY];
      DaySchedule? thursdaySchedule = scheduleMap?[DayOfWeek.THURSDAY];
      DaySchedule? fridaySchedule = scheduleMap?[DayOfWeek.FRIDAY];
      DaySchedule? saturdaySchedule = scheduleMap?[DayOfWeek.SATURDAY];
      DaySchedule? sundaySchedule = scheduleMap?[DayOfWeek.SUNDAY];

      // This action can be performed on other days of the week.
      int? mondayFrom = mondaySchedule?.from;
      int? mondayTo = mondaySchedule?.to;
      bool? mondayDnd = mondaySchedule?.dnd;
    },
    onError: (e) {
      debugPrint("fetchPreferences:error ${e.toString()}");
    });

2. Update schedule preferences CometChatNotifications.updatePreferences() method is used to update a user’s notification preferences. The “override” toggle defined in the dashboard is crucial when updating preferences. If any preference is non-overridable, the method doesn’t generate an error; it instead returns the NotificationPreferences object with the updated values where overrides are allowed. This functionality can be beneficial for temporarily superseding certain user preferences to ensure notifications for a specific event are delivered. Nonetheless, it is advisable to use this approach temporarily to avoid confusing users with unexpected changes to their notification settings. It is unnecessary to specify all values; only set and save the preferences that have been changed.

JavaScript
Android
iOS
Flutter

// This is applicable for web, React native, Ionic cordova
// The example demonstrates modifying all values; however, modifying only the changed values is sufficient.

// Instantiate the NotificationPreferences.
const updatedPreferences = new NotificationPreferences();

// Instantiate the preferences that you want to update.
const mutePreferences = new MutePreferences();

// Change schedule preferences
const scheduleMap = new Map<DayOfWeek, DaySchedule>();
const mondaySchedule = new DaySchedule(2015, 2345, false);

scheduleMap.set(DayOfWeek.MONDAY, mondaySchedule);

mutePreferences.setSchedulePreference(scheduleMap);

// Load the updates in the NotificationPreferences instance.
updatedPreferences.setOneOnOnePreferences(oneOnOnePreferences);
updatedPreferences.setGroupPreferences(groupPreferences);
updatedPreferences.setMutePreferences(mutePreferences);

// Update the preferences and receive the udpated copy.
const preferences = await CometChatNotifications.updatePreferences(updatedPreferences);

// The example demonstrates modifying all values; however, modifying only the changed values is sufficient.
// Instantiate the NotificationPreferences.
NotificationPreferences updatedPreferences = new NotificationPreferences();

// Instantiate the preferences that you want to update.
MutePreferences mutePreferences = new MutePreferences();

// Change schedule preferences
Map scheduleMap = new ArrayMap<DayOfWeek, DaySchedule>();
DaySchedule mondaySchedule = new DaySchedule();
mondaySchedule.setFrom(2015);
mondaySchedule.setTo(2345);
mondaySchedule.setDnd(false);

scheduleMap.put(DayOfWeek.MONDAY, mondaySchedule);

mutePreferences.setSchedulePreference(scheduleMap);

// Load the updates in the NotificationPreferences instance.
updatedPreferences.setMutePreferences(mutePreferences);

// Update the preferences.
CometChatNotifications.updatePreferences(updatedPreferences, new CometChat.CallbackListener<NotificationPreferences>() {
    @Override
    public void onSuccess(NotificationPreferences notificationPreferences) {
        // Updated notificationPreferences
    }

    @Override
    public void onError(CometChatException e) {
        // Something went wrong
    }
});

// The example demonstrates modifying all values; however, modifying only the changed values is sufficient.

// Instantiate the NotificationPreferences.
let updatedPreferences = CometChatNotifications.NotificationPreferences();

// Instantiate the preferences that you want to update.
let mutePreferences = CometChatNotifications.MutePreferences();

// Change schedule preferences
var dictionary = [CometChatNotifications.DayOfWeek:CometChatNotifications.DaySchedule]();
dictionary[.MONDAY] = CometChatNotifications.DaySchedule(from: 2015, to: 2345, dnd: false)
mutePreferences.set(schedulePreference: dictionary)

// Load the updates in the NotificationPreferences instance.
updatedPreferences.set(mutePreferences: mutePreferences);

// Update the preferences.
CometChatNotifications.updatePreferences(updatedPreferences) { updatedPreferences in
    print("updatePreferences: \(updatedPreferences)")
} onError: { error in
    print("updatePreferences: \(error.errorCode) \(error.errorDescription)")
}

// The example demonstrates modifying all values; however, modifying only the changed values is sufficient.

// Instantiate the NotificationPreferences
NotificationPreferences updatedPreferences = NotificationPreferences();

// Instantiate the preferences that you want to update.
MutePreferences mutePreferences = MutePreferences(dnd: DNDOptions.DISABLED);
Map<DayOfWeek, DaySchedule> scheduleMap = {};

DaySchedule mondaySchedule = DaySchedule(from: 2015, to: 2345, dnd: false);
scheduleMap[DayOfWeek.MONDAY] = mondaySchedule;

mutePreferences.schedule = scheduleMap;
updatedPreferences.mutePreferences = mutePreferences;

// Update the preferences.
CometChatNotifications.updatePreferences(updatedPreferences,
    onSuccess: (preferencesAfterUpdate) {
  debugPrint("updatePreferences:success");
  // Use the preferencesAfterUpdate
}, onError: (e) {
  debugPrint("updatePreferences:error: ${e.toString()}");
});

Bypass preferences for mentions

If this setting is enabled, end users who have enabled Do Not Disturb (DND), muted a conversation, or set up a schedule will still receive notifications when they are mentioned in a new message or reply.

Bypass preferences for @all

If this setting is enabled, end users who have enabled Do Not Disturb (DND), muted a conversation, or set up a schedule will still receive notifications when @all (a mention that notifies all group members) is used in a group message. This ensures all group members are notified regardless of their individual notification preferences.

Calls preferences

Push notifications are triggered for calling events. These notifications are not delivered via Email or SMS.

Events	Available preferences	Can user override?
Call initiated	• Don’t notify • Notify (Default)	No
Call ongoing	• Don’t notify • Notify (Default)	No
Call cancelled	• Don’t notify • Notify (Default)	No
Call rejected	• Don’t notify • Notify (Default)	No
Call unanswered	• Don’t notify • Notify (Default)	No
Call busy	• Don’t notify • Notify (Default)	No
Call ended	• Don’t notify • Notify (Default)	No

Reset preferences

CometChatNotifications.resetPreferences() method is used to reset the preferences for a user to their default state. The default state of preferences is defined by the CometChat administrator via the dashboard.

JavaScript
Android
iOS
Flutter

// This is applicable for web, React native, Ionic cordova
const defaultPreferences = await CometChatNotifications.resetPreferences();

CometChatNotifications.resetPreferences(new CometChat.CallbackListener<NotificationPreferences>() {
    @Override
    public void onSuccess(NotificationPreferences defaultPreferences) {
        // Display the defaultPreferneces.
    }

    @Override
    public void onError(CometChatException e) {
        // Something went wrong.
    }
});

CometChatNotifications.resetPreferences { defaultPreferences in
    print("resetPreferences: defaultPreferences \(defaultPreferences)");
} onError: { error in
    print("resetPreferences: \(error.errorCode) \(error.errorDescription)");
}

CometChatNotifications.resetPreferences(onSuccess: (defaultPreferences) {
  debugPrint("resetPreferences:success");
  // defaultPreferences are available after reset.
},onError: (e) {
  debugPrint("resetPreferences:error ${e.toString()}");
});

Push notification preferences

The notification payload sent to FCM, APNs, or custom providers can be customized to include the CometChat message object for new messages and replies. To comply with the 4 KB payload size limit required by FCM and APNs, specific parts of the message object can be excluded to reduce the payload size. Additionally, a custom payload in the form of a JSON object can be included in the push payload.

Payload setting	Available preferences
Include CometChat message object	• false (Default) • true
Include Sender’s metadata	• false • true (Default)
Include Receiver’s metadata	• false • true (Default)
Include message metadata	• false • true (Default)

Common templates and sounds

Templates are designed to specify the content displayed in notifications on the user’s device for different events. Templates incorporate placeholders, which reference specific pieces of information determined by properties from the event. For example, New message event has the following structure:

{
  "data": {
    "id": "17",
    "conversationId": "group_cometchat-guid-1",
    "sender": "cometchat-uid-2",
    "receiverType": "group",
    "receiver": "cometchat-guid-1",
    "category": "message",
    "type": "text",
    "data": {
      "text": "Hello! How are you?",
      "entities": {
        "sender": {
          "entity": {
            "uid": "cometchat-uid-2",
            "name": "George Alan",
            "role": "default",
            "avatar": "https://assets.cometchat.io/sampleapp/v2/users/cometchat-uid-2.webp",
            "status": "available",
            "lastActiveAt": 1707901272
          },
          "entityType": "user"
        },
        "receiver": {
          "entity": {
            "guid": "cometchat-guid-1",
            "icon": "https://assets.cometchat.io/sampleapp/v2/groups/cometchat-guid-1.webp",
            "name": "Hiking Group",
            "type": "public",
            "owner": "cometchat-uid-1",
            "createdAt": 1706014061,
            "conversationId": "group_cometchat-guid-1",
            "onlineMembersCount": 3
          },
          "entityType": "group"
        }
      },
    },
    "sentAt": 1707902030,
    "updatedAt": 1707902030
  }
}

The sender’s name is accessible via data.entities.sender.name, so the placeholder for the sender’s name will be {{message.data.entities.sender.name}}. This placeholder is substituted within the template with the actual name of the sender aka the substitution value. As an administrator, you can configure:

Default templates - Use these templates to display previews by leveraging the information contained in the event.
Privacy templates - Employ these templates to present generic content in the notification.

Privacy setting

Dashboard configuration

Configure which template will be used for displaying the content of the notifications displayed on user’s devices. The available preferences are:

Use default template - Enforces the use of default templates for all the users.
Use privacy template - Enforces the use of privacy templates for all the users.
Use default templates with user privacy override (Default) - Uses default templates by default, but allows the users to enable privacy to hide the previews.

Client-side implementation

1. Fetch privacy setting The method CometChatNotifications.fetchPreferences() retrieves the notification preferences saved by the user as an instance of NotificationPreferences class. If the user has not configured any preferences, the default preferences defined by the CometChat administrator via the dashboard will be utilized.

JavaScript
Android
iOS
Flutter

// This is applicable for web, React native, Ionic cordova
const preferences = await CometChatNotifications.fetchPreferences();

// Display a toggle for use privacy option TODO
const usePrivacyTemplate = preferences.getUsePrivacyTemplate();

CometChatNotifications.fetchPreferences(new CometChat.CallbackListener<NotificationPreferences>() {
  @Override
  public void onSuccess(NotificationPreferences notificationPreferences) {
      // Display a toggle for use privacy option
      boolean usePrivacyTemplate = notificationPreferences.getUsePrivacyTemplate();
  }

  @Override
  public void onError(CometChatException e) {
      // Something went wrong while fetching notification preferences
  }
});

CometChatNotifications.fetchPreferences { notificationPreferences in
  // Display a toggle for use privacy option
  let usePrivacyTemplate = notificationPreferences.usePrivacyTemplate;

} onError: { error in
  // Something went wrong while fetching notification preferences.
  print("fetchPreferences: \(error.errorCode) \(error.errorDescription)");
}

CometChatNotifications.fetchPreferences(
    onSuccess: (notificationPreferences) {
      // Display a toggle for use privacy option
      bool? usePrivacyTemplate = notificationPreferences.usePrivacyTemplate;

    },
    onError: (e) {
      debugPrint("fetchPreferences:error ${e.toString()}");
    });

2. Update privacy setting CometChatNotifications.updatePreferences() method is used to update a user’s notification preferences. The “override” toggle defined in the dashboard is crucial when updating preferences. If any preference is non-overridable, the method doesn’t generate an error; it instead returns the NotificationPreferences object with the updated values where overrides are allowed.

Note: The “Body (Fallback)” value is utilized when any placeholders within the “Body” fail to resolve to an appropriate substitution value. For example, if {{message.data.text}} in the aforementioned scenario evaluates to null or undefined, the “Body (Fallback)” value will be utilized. Ideally, the “Body (Fallback)” value should not contain any placeholders to prevent additional resolution failures.

Sounds

The sound files must be included within the app’s bundle. These values are set within the notification payload as values of the “sound” field. Sound for Call Notifications: Specify the name of the sound file you wish to play for call notifications. Sound for Chat Notifications: Specify the name of the sound file you wish to play for chat notifications.

Email notification templates

You can use a default template or a privacy template in case you consider the information to be displayed as sensitive. The data available for email’s subject template is as follows:

For one-on-one conversation
For group conversation
