BotMan gives you the ability to listen to driver specific events, such as when a person joins your Slack channel or a Facebook message gets read. You can then perform various tasks when these events happen and reply to your chatbot users.
You may listen to driver events using a simple and easy API. The BotMan object provides an on
method that takes an event name and a closure/callable to execute once the event occurs.
All callbacks will receive the event payload and the BotMan instance as parameters.
$botman->on('event', function($payload, $bot) {
});
Please refer to each messaging service documentation to get a list of available events.
