Use the Trigger event to condition on parameters of the workflow's trigger event. The condition settings are dependent on the type of trigger event.
Click on the "Add Trigger Event Condition" option.
The condition settings will open. The event type is already preset according to the trigger event and cannot be changed.
To define the event, click on the "Add Attribute" button.
Select the attribute that the trigger event should have.
Select the operator - the list of available operators depends on the trigger event type.
Select the desired values in the rightmost field —for example, states of a reservation.
