response or reply with block message?

[1kko]

I discovered from slack api that can be using rich messaging called "block".
https://api.slack.com/messaging/composing/layouts

I tried to send using send_webapi(), but it fails.
Is there a way to send it?

msg={
  "channel": "C1H9RESGL",
  "blocks": [
    {
      "type": "section",
      "text": {
        "type": "mrkdwn",
        "text": "Danny Torrence left the following review for your property:"
      }
    },
    {
      "type": "section",
      "block_id": "section567",
      "text": {
        "type": "mrkdwn",
        "text": "<https://google.com|Overlook Hotel> \n :star: \n Doors had too many axe holes, guest in room 237 was far too rowdy, whole place felt stuck in the 1920s."
      },
      "accessory": {
        "type": "image",
        "image_url": "https://is5-ssl.mzstatic.com/image/thumb/Purple3/v4/d3/72/5c/d3725c8f-c642-5d69-1904-aa36e4297885/source/256x256bb.jpg",
        "alt_text": "Haunted hotel image"
      }
    },
    {
      "type": "section",
      "block_id": "section789",
      "fields": [
        {
          "type": "mrkdwn",
          "text": "*Average Rating*\n1.0"
        }
      ]
    }
  ]
}

message.send_webapi('',json.dumps(msg)) # fails with slacker.Error: no_text
message.send_webapi('test',json.dumps(msg)) # I only get 'test' text in reply.
