Delivery & Read Receipts

Mark messages as delivered, read, or unread and receive real-time receipt events using the CometChat React Native SDK.

AI Integration Quick Reference

Method	Description
markAsDelivered(message)	Mark a message as delivered
markAsRead(message)	Mark a message as read
markConversationAsDelivered(id, type)	Mark entire conversation as delivered
markConversationAsRead(id, type)	Mark entire conversation as read
markMessageAsUnread(message)	Mark a message as unread
getMessageReceipts(messageId)	Get delivery/read receipts for a message

// Mark as delivered/read (pass message object)
CometChat.markAsDelivered(message);
CometChat.markAsRead(message);

// Mark entire conversation
CometChat.markConversationAsRead("UID", "user");

// Listen for receipt events
CometChat.addMessageListener("LISTENER_ID", new CometChat.MessageListener({
  onMessagesDelivered: (receipt) => { },
  onMessagesRead: (receipt) => { },
  onMessagesDeliveredToAll: (receipt) => { },  // Groups only
  onMessagesReadByAll: (receipt) => { }        // Groups only
}));

Delivery and read receipts track whether messages have been delivered to and read by recipients.

CometChat.markConversationAsRead(conversationWith, conversationType).then(

CometChat.markConversationAsRead(conversationWith, conversationType).then(
  (response: string) => {
    console.log("Conversation marked as read", response);
  },
  (error: CometChat.CometChatException) => {
    console.log("Error:", error);
  }
);

JavaScript (Group)

Real-Time Receipt Events

Register a MessageListener to receive delivery and read receipt events.

Callback	Description
onMessagesDelivered	Message delivered to a user
onMessagesRead	Message read by a user
onMessagesDeliveredToAll	Group message delivered to all members
onMessagesReadByAll	Group message read by all members

TypeScript

let listenerID: string = "UNIQUE_LISTENER_ID";

CometChat.addMessageListener(
  listenerID,
  new CometChat.MessageListener({
    onMessagesDelivered: (messageReceipt: CometChat.MessageReceipt) => {
      console.log("Message delivered:", messageReceipt);
    },
    onMessagesRead: (messageReceipt: CometChat.MessageReceipt) => {
      console.log("Message read:", messageReceipt);
    },
    onMessagesDeliveredToAll: (messageReceipt: CometChat.MessageReceipt) => {
      console.log("Message delivered to all group members:", messageReceipt);
    },
    onMessagesReadByAll: (messageReceipt: CometChat.MessageReceipt) => {
      console.log("Message read by all group members:", messageReceipt);
    }
  })
);

JavaScript

let listenerID = "UNIQUE_LISTENER_ID";

CometChat.addMessageListener(
  listenerID,
  new CometChat.MessageListener({
    onMessagesDelivered: (messageReceipt) => {
      console.log("Message delivered:", messageReceipt);
    },
    onMessagesRead: (messageReceipt) => {
      console.log("Message read:", messageReceipt);
    },
    onMessagesDeliveredToAll: (messageReceipt) => {
      console.log("Message delivered to all group members:", messageReceipt);
    },
    onMessagesReadByAll: (messageReceipt) => {
      console.log("Message read by all group members:", messageReceipt);
    }
  })
);

You will receive events in the form of MessageReceipt objects containing the following parameters:

Parameter	Information
messageId	The ID of the message prior to which all the messages for that particular conversation have been marked as read.
sender	User object containing the details of the user who has marked the message as read. System User for deliveredToAll & readByAll events.
receiverId	ID of the receiver whose conversation has been marked as read.
receiverType	Type of the receiver (user/group)
receiptType	Type of the receipt (read/delivered)
deliveredAt	The timestamp of the time when the message was delivered. Only present if the receiptType is delivered.
readAt	The timestamp of the time when the message was read. Only present when the receiptType is read.

The markAsDelivered() and markAsRead() methods are fire-and-forget — they do not return a MessageReceipt object. Use the listener callbacks above to receive delivery and read confirmations.

The following features require Enhanced Messaging Status to be enabled for your app:

• onMessagesDeliveredToAll event
• onMessagesReadByAll event
• deliveredAt field in group messages
• readAt field in group messages
• markMessageAsUnread() method

Always remove listeners when no longer needed to prevent memory leaks. In React Native, place this in a cleanup function inside useEffect or in componentWillUnmount.

CometChat.removeMessageListener("UNIQUE_LISTENER_ID");

MessageReceipt Object

The listener callbacks receive a MessageReceipt object:

Field	Getter	Return Type	Description
messageId	getMessageId()	string	ID of the message
sender	getSender()	User	User who triggered the receipt
receiverId	getReceiverId()	string	ID of the receiver
receiverType	getReceiverType()	string	"user" or "group"
receiptType	getReceiptType()	string	"delivery" or "read"
deliveredAt	getDeliveredAt()	number	Timestamp when delivered
readAt	getReadAt()	number	Timestamp when read

Get Receipt History

Use getMessageReceipts() to fetch delivery and read receipts for a specific message. Useful for group messages to see which members have received/read the message.

TypeScript

let messageId: number = 123;

CometChat.getMessageReceipts(messageId).then(
  (receipts: CometChat.MessageReceipt[]) => {
    console.log("Message receipts:", receipts);
  },
  (error: CometChat.CometChatException) => {
    console.log("Error fetching receipts:", error);
  }
);

JavaScript

let messageId = 123;

CometChat.getMessageReceipts(messageId).then(
  (receipts) => {
    console.log("Message receipts:", receipts);
  },
  (error) => {
    console.log("Error fetching receipts:", error);
  }
);

Returns an array of MessageReceipt objects.

Missed Receipts

When fetching messages, each message object includes deliveredAt and readAt timestamps indicating when the message was delivered and read.

let deliveredAt = message.getDeliveredAt();
let readAt = message.getReadAt();

Mark as Unread

Use markMessageAsUnread() to mark a message as unread. This is useful for “mark as unread” functionality in conversation lists.

You cannot mark your own messages as unread. This method only works for messages received from other users.

TypeScript

CometChat.markMessageAsUnread(message).then(
  (conversation: CometChat.Conversation) => {
    console.log("Message marked as unread:", conversation);
    console.log("Unread message count:", conversation.getUnreadMessageCount());
  },
  (error: CometChat.CometChatException) => {
    console.log("Error marking as unread:", error);
  }
);

JavaScript

CometChat.markMessageAsUnread(message).then(
  (conversation) => {
    console.log("Message marked as unread:", conversation);
    console.log("Unread message count:", conversation.getUnreadMessageCount());
  },
  (error) => {
    console.log("Error marking as unread:", error);
  }
);

Parameter	Type	Description
message	BaseMessage	The message object to mark as unread
