Facebook - get all posts from a page

Question

The response from the request to receive messages about a specific conversation returns only identifiers from all the individual messages contained in this conversation. Therefore, if I want to receive all messages from all conversations, there will be many requests ...

Is there any solution for getting all messages (text from messages) from a specific conversation in one request? Or any other workaround for this kind of problem?

Here is an example:

Request: XXX?fields=subject,message_count,messages→ (where XXX is the conversation identifier) ​​Answer:

{
  "message_count": 4,
  "id": "XXX",
  "messages": {
    "data": [
      {
        "created_time": "2016-05-11T08:29:56+0000",
        "id": "id1"
      },
      {
        "created_time": "2016-05-11T08:29:54+0000",
        "id": "id2"
      },
      {
        "created_time": "2016-05-11T08:21:56+0000",
        "id": "id3"
      },
      {
        "created_time": "2016-05-09T14:04:17+0000",
        "id": "id4"
      }
    ]
  }
}
