List changelogs of messages

Each message changelog has distinct properties such as the timestamp of an updated message or the unique ID of a deleted message. Based on these two properties, you can retrieve message changelogs using either the timestamp or the token. Both the getMessageChangeLogsSinceToken() and getMessageChangeLogsSinceTimestamp() methods require a parameter MessageChangeLogsParams object to determine which messages to return.

Kotlin

val params = MessageChangeLogsParams().apply {
    replyType = ReplyType.ALL // or ReplyType.ONLY_REPLY_TO_CHANNEL, ReplyType.NONE
    messagePayloadFilter = MessagePayloadFilter().apply {
        includeThreadInfo = INCLUDE_THREAD_INFO
        includeParentMessageInfo = PARENT_MESSAGE_INFO
    }
}

MessageChangeLogsParams

Property name	Type	Description
replyType	string	Specifies the type of message to include in the results. - `NONE` (default): Includes unthreaded messages and only the parent messages of threaded messages. - `ALL`: Includes both threaded and unthreaded messages. - `ONLY_REPLY_TO_CHANNEL`: Includes unthreaded messages, parent messages of threaded messages, and messages sent to the channel as replies with the `reply_to_channel` property set to `true`.
includeThreadInfo	boolean	Determines whether to include the thread information of the messages in the result. (Default: `false`)
includeParentMessageInfo	boolean	Determines whether to include the information of the parent messages in the result. (Default: `false`)

By timestamp

You can retrieve the message changelogs by specifying a timestamp. The results only include changelogs that were created after the specified timestamp.

Note: The getMessageChangeLogsByTimestamp method is deprecated. Accordingly, use the getMessageChangeLogsSinceTimestamp() method instead.

Kotlin

channel.getMessageChangeLogsSinceTimestamp(TIMESTAMP, params) { updatedMessages, deletedMessageIds, hasMore, token, e ->
    if (e != null) {
        // Handle error.
    }

    // A list of message changelogs created after the specified timestamp is successfully retrieved.
}

List of parameters

Parameter name	Type	Description
ts	long	Specifies a timestamp to be the reference point for the changelogs to be retrieved, in Unix milliseconds format.
params	MessageChangeLogsParams	Contains a set of parameters you can use when retrieving changelogs.

By token

You can also retrieve message changelogs by specifying a token. The token is an opaque string that marks the starting point of the next page in the result set and it's included in the callback of the previous call. Based on the token, the next page starts with changelogs that were created after the specified token.

Kotlin

channel.getMessageChangeLogsSinceToken(TOKEN, params) { updatedMessages, deletedMessageIds, hasMore, token, e ->
    if (e != null) {
        // Handle error.
    }

    // A list of message changelogs created after the specified token is successfully retrieved.
}

List of parameters

Parameter name	Type	Description
token	string	Specifies a token to be the reference point for the changelogs to be retrieved.
params	MessageChangeLogsParams	Contains a set of parameters you can use when retrieving changelogs.
