A bot_message is sent when a message is sent to a channel by an integration "bot". It is like a normal user message, except it has no associated user.
The bot_id tells you which bot sent this message. The username and icon to
use can be looked up by passing this to bots.info. Some bot_messages also include username
and/or icons properties. If present these override the default username or
icon for this bot.
When an event occurs, we will send an HTTP POST request to your Request URL. The outer payload is uniform across all Events API methods, and contains fields like team_id and event. Learn more
