TransitionRoute

A transition route specifies a intent that can be matched and/or a data condition that can be evaluated during a session. When a specified transition is matched, the following actions are taken in order:

  • If there is a triggerFulfillment associated with the transition, it will be called.
  • If there is a targetPage associated with the transition, the session will transition into the specified page.
  • If there is a targetFlow associated with the transition, the session will transition into the specified flow.
