Reference documentation and code samples for the Google Cloud Dialogflow Cx V3 Client class TransitionRoute.
A transition route specifies aintentthat 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 atrigger_fulfillmentassociated with the transition, it will be called.
If there is atarget_pageassociated with the transition, the session will transition into the
specified page.
If there is atarget_flowassociated with the transition, the session will transition into the
specified flow.
