Event types destined to be processed by Adobe Campaign must be created in the control instance. This can be done via the Administration > Platform > Enumerations folder of the tree. Each event type matches a value in the eventType enumeration. This can be an order confirmation, password or order delivery change, etc.
For more on itemized lists, refer to Enumeration management.
Once the itemized list values have been created, log off and back on to your instance for the creation to be effective.
