EventHandler

An event handler specifies an event that can be handled during a session. When the specified event happens, the following actions are taken in order:

  • If there is a triggerFulfillment associated with the event, it will be called.
  • If there is a targetPage associated with the event, the session will transition into the specified page.
  • If there is a targetFlow associated with the event, the session will transition into the specified flow.

Fields

string

Output only. The unique identifier of this event handler.

event

string

Required. The name of the event to handle.

triggerFulfillment

The fulfillment to call when the event occurs. Handling webhook errors with a fulfillment enabled with webhook could cause infinite loop. It is invalid to specify such fulfillment for a handler handling webhooks.

targetPage

string

The target page to transition to. Format: projects/<Project ID>/locations/<Location ID>/agents/<Agent ID>/flows/<Flow ID>/pages/<Page ID>.

targetFlow

string

The target flow to transition to. Format: projects/<Project ID>/locations/<Location ID>/agents/<Agent ID>/flows/<Flow ID>.
