Dialogflow: Events

Use events to trigger Dialogflow intents.

Aside from user input, events are also used to trigger intents. Any intents with the event name listed under the β€œEvents” section will be triggered when an event occurs.

A good example of this is the default WELCOME event, which is already built into Dialogflow. This event is triggered whenever a new user begins chatting with the bot.

Parametric URLs

Any intents with the events for REF_[PARAM] or REF_START_[PARAM] are triggered when the user arrives from a parametric URL.

Example: m.me/respondio?ref=[PARAM].

If you would like a custom parameter to trigger a Dialogflow intent, please ensure the parameter has a prefix of REF_ on the intent's event configuration. Example: REF_PARAM

Referring to the example above, if you want to trigger an intent from m.me/respondio?ref=medium , add REF_MEDIUM to the intent's event configuration.

Bear in mind that the REF prefix is not necessary for the WELCOME event as this event is a default event built into Dialogflow.
