Events

Events are asynchronous functions that do not return a response, they are useful for audit logs / reporting or handling any other side-effects.

You can specify a handler for any of these events below, for debugging or for an audit log.

note

The execution of your authentication API will be blocked by an await on your event handler. If your event handler starts any burdensome work it should not block its own promise on that work.
