How to set session timeout to 30 seconds

[oozturkplus]

Hi,
I use Google Dialogflow CX.
If there is no user activity in 30 seconds I want to terminate chatbot session.
There are examples or documentation as below, I tried somethings 
but didn't work. 
https://cloud.google.com/dialogflow/cx/docs/concept/session#long-lasting

If you have a concrete example which is work, please share with me.

Thanks.

Hi @oozturkplus,

Welcome to Google Cloud Community!

Dialogflow CX does not have a built-in mechanism to automatically terminate a session after 30 seconds of inactivity. The documentation you referenced discusses extending session lifespan, not shortening it. To implement a 30-second inactivity timeout, you will need to create a custom solution outside of Dialogflow CX. This involves integrating your Dialogflow CX agent with a custom application (such as a web application or serverless function) that handles the session timeout logic. Here are some approaches you can consider:

1. Client-Side Timer: Your client application (the chatbot interface) should implement a timer that starts when the user last interacts with the chatbot (e.g., sends a message).
2. Inactivity Detection: Once the timer reaches 30 seconds, the client application triggers a custom event, such as SESSION_TIMEOUT, to your Dialogflow CX agent.
3. Dialogflow CX Event Handler: You’ll need to set up an event handler in your Dialogflow CX agent to capture the SESSION_TIMEOUT event. This handler should handle the action of ending the session, possibly by transitioning to an "End Session" page.
4. Session Termination: The "End Session" page in Dialogflow CX should be configured to properly close the session, providing an appropriate message to the user if needed.
5. Webhook with session timer:

• Develop a webhook that tracks the last user activity time.
• When a new user interaction is received, reset the timer.
• If the timer elapses without any user activity (set to 30 seconds in your case), send a predefined message (e.g., "session expired") and terminate the session from your webhook.
