Platform events are provided by platform integrations. They are invoked when platform-specific events occur. See the documentation for your integration platform for details on platform-specific events.
Welcome events
Welcome events are invoked when a conversation is started. There are two types of welcome events:
- Generic welcome event:
The default welcome intent
is automatically created when you create an agent.
This intent is preconfigured to handle the generic welcome event:
WELCOME. - Platform-specific welcome events:
Each platform invokes a platform-specific welcome event
when a conversation starts.
For example, if an end-user clicks the Get started button
to start a chat with your Facebook Messenger bot, the
FACEBOOK_WELCOMEevent is invoked.
When a platform-specific welcome event is invoked, Dialogflow triggers any intent that is configured for the event. If no intent is configured for the platform-specific welcome event, Dialogflow invokes the generic welcome event, which triggers the default welcome intent.
Google Assistant events
Dialogflow events are referred to as "intents" in Google Assistant documentation. For more information and a list of events, see the reference documentation for Google Assistant intents.
