Updating messages (deprecated)

Use Chat SDKs

This documentation is deprecated. Use any of our dedicated Chat SDKs to quickly implement chat functionality in your application.

Since PubNub stores all messages in a time-series database, it doesn’t expose an API to directly update a message. However, clients can update messages by passing another version of the message using the Message Reactions feature.

User ID / UUID

User ID is also referred to as UUID/uuid in some APIs and server responses but holds the value of the userId parameter you set during initialization.

Update a message

Use the addMessageAction method to update a published message after it has been published by adding an action to it.

JavaScript

1pubnub.addMessageAction(
2  {
3    channel: 'main'
4    messageTimetoken: '15610547826970040',
5    action: {
6      type: 'updated',
7      value: 'Hello World! (fixed typo)',
8    },
9  },
10  function(status, response) {
11  }
12);

Swift

1extension MyAppMessageAction: MessageAction {}
2

3let action = MyAppMessageAction(type: "updated", value: "Hello World! (fixed typo)")
4

5pubnub.addMessageAction(
6  channel: "main",
7  message: action,
8  messageTimetoken: 15610547826970040
9) { result in
10  switch result {
11  case let .success(response):
12    print("Successfully Message Reaction Add Response: \(response)")
13  case let .failure(error):
14    print("Error from failed response: \(error.localizedDescription)")
15  }
16})

Message update event

PubNub triggers events when messages are updated using message reactions. Clients subscribed to the channel will receive these events.
