Disappearing Messages - CometChat Docs

The Disappearing Messages extension allows end-users to send messages that disappear after a certain interval of time. This extension works for both private (one-on-one) and group messages. This extension is also known as exploding messages on some platforms.

Extension settings

Login to CometChat and select your app.
Navigate to Chat & Messaging → Features and enable Disappearing messages under Extensions.

How does it work?

Once the messages are sent, you can immediately schedule them for deletion using the disappearing messages extension. The message with the mentioned msgId gets deleted at timeInMS.

The value of timeInMS should strictly be less than 1 year

This extension uses the callExtension method provided by the CometChat SDK.

CometChat.sendMessage(textMessage) // Can be any type of message
  .then(message => {
  	CometChat.callExtension('disappearing-messages','DELETE','v1/disappear',{
    	msgId: message.id, // The id of the message that was just sent
    	timeInMS: 1633521809051 // Time in milliseconds. Should be a time from the future.
  	}).then(response => {
      // Successfully scheduled for deletion
    })
  
  	// Logic to display the sent message on the screen.
  	// ...
	}).catch(error => {
  	// Error occured
	});

import org.json.simple.JSONObject;

JSONObject body=new JSONObject();
body.put("msgId", ID_OF_THE_SENT_MESSAGE);
body.put("timeInMS", 1633521809051); // Change to a future timestamp

// Once the message is sent successfully, call this.
CometChat.callExtension("disappearing-messages", "DELETE", "/v1/disappear", body,
	new CometChat.CallbackListener<JSONObject>() {
    @Override
    public void onSuccess(JSONObject responseObject) {
        // Will disappear successfully.
    }

    @Override
    public void onError(CometChatException e) {
      	// Some error occured.
    }
});

// Once a message is sent successfully, call this.
// Change the timeInMS to a future timestamp.
CometChat.callExtension(slug: "disappearing-messages", type: .delete, endPoint: "v1/disappear", body: ["msgId":SENT_MESSAGE_ID, "timeInMS": 1633521809051], onSuccess: { (response) in
	// Will disappear successfully
}) { (error) in
  // Some error occured
