Publishing Events
====================

Envase Connect allows a wide variety of events to be published. The
specific details of the structure of each Event, including required
properties and accepted property values, can be found here: :ref:`Events<Events>`

Below is an example of a Gate “Arrived” Event:

equipment check in/out or verify the booking number given is a valid
booking.
