Enumeration of the types of events available.

CONVERSATION_STARTED A new conversation has been opened. This is fired when a telephone call is answered, or a conversation is created via the API.
CONVERSATION_FINISHED An existing conversation has closed. This is fired when a telephone call is terminated, or a conversation is closed via the API.
HUMAN_INTERVENTION_NEEDED An existing conversation has received notification from Dialogflow that human intervention is required.
NEW_MESSAGE An existing conversation has received a new message, either from API or telephony. It is configured in ConversationProfile.new_message_event_notification_config

Unrecoverable error during a telephone call.

In general non-recoverable errors only occur if something was misconfigured in the ConversationProfile corresponding to the call. After a non-recoverable error, Dialogflow may stop responding.

We don't fire this event:

  • in an API call because we can directly return the error, or,
  • when we can recover from an error.
