PubNub Message Update & Delete Features - NEW

Update Published Messages using the Message Actions feature.

pubnub.addMessageAction(
  {
    channel: 'chats.room123'
    messageTimetoken: '15610547826970040',
    action: {
      type: 'updated',
      value: 'Hello World! (edited)',
    },
  },
  function(status, response) {
  }
);

Delete Messages using the deleteMessages API.

There is a setting to accept delete from history requests for a key, which you must enable by checking the Enable Delete-From-History checkbox in the key settings for your key in the Admin Portal. Requires Initialization with the secret key.

pubnub.deleteMessages(
  {
    channels: 'chats.room1',
    start: "15526611838554309",
    end: "15526611838554310",
  },
  function (status, response) {
    console.log(status, response);
  }
);

Soft Delete a Message, using the Message Actions feature.

"action": {
  "type": "deleted",
  "value": "."
}
