# Create a group of timeline events

> Update an existing property for a specified timeline event type. The id passed in the JSON body needs to match the id of an existing property or this will return a 404 error.  Properties cannot be moved from one event type to another, so the eventTypeId included in the JSON body must match the event-type-id in the URL. Please note that the name cannot be updated.

  if (!scopes || scopes.length === 0) {
