POST /interaction/v1/eventDefinitions

Creates an event definition (name and data schema for an event) and defines an event definition key. The resource uses this key when firing an event to send it to the appropriate journey. Typically, marketers create the event definition in the Journey Builder UI. Use this resource instead if you’re using a custom application for Journey Builder functionality. To call this resource, assign your API Integration the Automation | Interactions | Read scope.
