Slackbot doesn't stick to the slack api

[bqv]

Example message.bot_message:

{
	"text": "Your file was uploaded \u2014 it\u2019s safe and sound in Slack. Unfortunately your workspace doesn\u2019t have any storage space left. To get more space, you can <https:\/\/hacksoc-y ork.slack.com\/pricing?ui_element=5&amp;ui_step=70|upgrade to a paid account> or delete some of your older files.",
	"is_ephemeral": true,
	"username": "slackbot",
	"type": "message",
	"subtype": "bot_message",
	"user": "USLACKBOT",
	"channel": "C501C2XU6",
	"ts": "1525883688.000000",
	"event_ts": "1525883688.000225"
}

Expected format:

{
    "type": "message",
    "subtype": "bot_message",
    "ts": "1358877455.000010",
    "text": "Pushing is the answer",
    "bot_id": "BB12033",
    "username": "github",
    "icons": {}
}

(Thank you for this thoroughly well designed api, slack.)
