Explore in Dialogflow
Click Continue to import our Conversation exits sample in Dialogflow. Then, follow the steps below to deploy and test the sample:
- Enter an agent name and create a new Dialogflow agent for the sample.
- After the agent is done importing, click Go to agent.
- From the main navigation menu, go to Fulfillment.
- Enable the Inline Editor, then click Deploy. The editor contains the sample code.
- From the main navigation menu, go to Integrations, then click Google Assistant.
- In the modal window that appears, enable Auto-preview changes and click Test to open the Actions simulator.
- In the simulator, enter
Talk to my test app
to test the sample!
Whenever users want to exit mid-conversation, they can say things like:
- "exit"
- "cancel"
- "stop"
- "nevermind"
- "goodbye"
By default, the Assistant exits your conversation and plays an earcon.
To override this behavior, you can opt-in to receiving one last request that you
can use to cleanup your fulfillment logic and respond to the user one last time.
Your final response must be a single simple response
with a 60-character limit on its textToSpeech
and displayText
values.
The maximum execution time allowed for conversation exit requests is 2 seconds; if no response is received, the conversation will end with the default exit earcon. If your custom cancel response fails (due to exceeding character limit, improper response type, etc) the conversation will also end with the default exit earcon.
Dialogflow
To receive conversation exit events:
- In the left navigation, click the + icon by the Intents menu item.
- Give the intent a name (like
Exit Conversation
) and click on the Events section. - Enter
actions_intent_CANCEL
in the Add event field. - Either specify a response under Response or set up your own response for this intent in your webhook code.
- Enable Set this intent as end of conversation.
- Click Save.
- In the left navigation, click Integrations.
- Choose Google Assistant and click Update draft, then Test to make sure the changes are reflected in your project.
When a user requests a conversation exit, the intent you created is triggered and your response is returned to the user. For example, here's some fulfillment code that uses the client library to handle a cancel intent and return a response.
Node.js
const {dialogflow} = require('actions-on-google'); const functions = require('firebase-functions'); const app = dialogflow({debug: true}); app.intent('Exit Conversation', (conv) => { conv.close(`Okay, talk to you next time!`); }); exports.dialogflowFirebaseFulfillment = functions.https.onRequest(app);
Java

Actions SDK
To receive conversation exit intents:
-
In a
conversations
object inside your action package, declare that you want to receive theactions.intent.CANCEL
intent whenever a user wants to exit mid-conversation.{ a"ctions:" [ { d"escription:" D"efault Welcome Intent," n"ame:" M"AIN," f"ulfillment:" { c"onversationName:" c"onversation_1 " }, i"ntent:" { n"ame:" a"ctions.intent.MAIN " } } ], c"onversations:" { c"onversation_1:" { n"ame:" c"onversation_1," u"rl:" Y"OUR_ENDPOINT_URL," i"nDialogIntents:" [ { n"ame:" a"ctions.intent.CANCEL " } ] } } }a
-
When you receive a request with the
actions.intent.CANCEL
intent, clean up any fulfillment logic that you'd like and return an appropriate exit phrase to the user. For example, here's some fulfillment code that uses the client library to handle a cancel intent.Node.js
const {actionssdk} = require('actions-on-google'); const functions = require('firebase-functions'); const app = actionssdk({debug: true}); app.intent('actions.intent.MAIN', (conv) => { conv.ask(`Hi! Try saying 'exit' or 'cancel'`); }); app.intent('actions.intent.TEXT', (conv, input) => { conv.ask(`You said ${input}`); conv.ask(`Try saying 'exit' or 'cancel'`); }); app.intent('actions.intent.CANCEL', (conv) => { conv.close(`Okay, talk to you next time!`); }); exports.dialogflowFirebaseFulfillment = functions.https.onRequest(app);
