It is necessary that when sending the keyboard, the buttons do not squeeze into one line, but are transferred to different ones.
How to do it?
The code:

keyboard:JSON.stringify(
    {
      "one_time": false,
      "buttons": [
      [{
        "action": {
        "type": "text",
        "payload": "{\"button\": \"1\"}",
        "label": "Помощь"
    },
      "color": "negative"
    },
    {
        "action": {
        "type": "text",
        "payload": "{\"button\": \"1\"}",
        "label": "Бонус"

      },
    {
        "action": {
        "type": "text",
        "payload": "{\"button\": \"2\"}",
        "label": "Админы"

      "color": "positive"

Buttons render not in json data.
If there is no such possibility using the API flag for rendering, then no way.
