 end

# method = 'handle_' + event.type.tr('.', '_')

# event.type
# This will give the name of the event. In our case, it will give ‘charge.dispute.created’ and replace the ‘.’ with ‘_’ so it will become ‘charge_dispute_created’ and concat it with ‘handle_’.
# so it becomes ‘handle_charge_dispute_created’ as a method.

# send method, event

# This will call the method based on the method variable value. In our case, it will call ‘handle_charge_dispute_created’
# Same way it will handle the other events based on your events you need to define the method in service put your code in it!
