List replies in a message thread

You can retrieve replies to a message by identifying the parent message like the following. First, create a ThreadMessageListParams object and set properties related to the thread where the target replies belong to.

Kotlin

// Create a ThreadMessageListParams object.
val params = ThreadMessageListParams().apply {
    previousResultSize = PREV_RESULT_SIZE
    nextResultSize = NEXT_RESULT_SIZE
    inclusive = INCLUSIVE
    reverse = REVERSE
    messagePayloadFilter = MessagePayloadFilter().apply {
        includeThreadInfo = INCLUDE_THREAD_INFO
        includeParentMessageInfo = INCLUDE_PARENT_MESSAGE_INFO
    }
}

ThreadMessageListParams

Property name	Type	Description
previousResultSize	int	Specifies the number of messages to retrieve that were sent before the specified timestamp.
nextResultSize	int	Specifies the number of messages to retrieve that were sent after the specified timestamp.
inclusive	boolean	Determines whether to include the messages with the matching timestamp in the result.
reverse	boolean	Determines whether to sort the retrieved messages in reverse order. If set to `false`, the result is displayed in ascending order.
includeThreadInfo	boolean	Determines whether to include information about the message thread in the result.
includeParentMessageInfo	boolean	Determines whether to include information about the parent message in the result. (Default: `false`)

Using the timestamp of the parent message, you can retrieve the parent message with its replies by passing a ThreadMessageListParams object as an argument to the parameter in the getThreadedMessagesByTimestamp() method.

KotlinKTX

parentMessage.getThreadedMessagesByTimestamp(ts, params) { parentMessage, messages, e ->
    if (e != null) {
        // Handle error.
    }

    // A list of replies of the specified parent message timestamp is successfully retrieved.
    // ...
}

List of parameters

Parameter name	Type	Description
ts	long	Specifies the timestamp to be the reference point of message retrieval in Unix milliseconds format.
