You can now reply to specific messages through application channels.

{
  "type": "message",
  "payload": {
    [MESSAGE BODY]
  },
  "metadata": {
      "external_conversation_ids": string[], // External identifier of the conversations related to this message.
      "referenced_message_external_id": string // (Optional) ID of the message being referenced as a direct reply
  }
}

As part of this change, we are introducing two new properties in the metadata object used when creating or replying to messages in a channel:

• external_conversation_ids—a string array containing the external conversation identifiers, which you use when creating or receiving messages. This property replaces external_conversation_id, which is now deprecated in the metadata object. This change allows you to send multiple external conversation IDs instead of just one.
• reference_message_external_id—the external identifier of the message you want to reply to.
