This intent is preconfigured to handle the generic welcome event: `WELCOME`.\n- **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_WELCOME` event](/dialogflow/docs/integrations/facebook#events) is invoked.\n\nWhen a platform-specific welcome event is invoked,\nDialogflow triggers any intent that is configured for the event.\nIf no intent is configured for the platform-specific welcome event,\nDialogflow invokes the generic welcome event,\nwhich triggers the default welcome intent.\n\nGoogle Assistant events\n-----------------------\n\nDialogflow events are referred to as \"intents\" in Google Assistant documentation.\nFor more information and a list of events, see the\n[reference documentation for Google Assistant intents](https://developers.google.com/assistant/conversational/reference/rest/intents)."]]
