This example shows how you can use quick replies to send a lightweight employee survey to an employee.
Note: This sample app doesn't implement any data store; the implementation of storage is left to you.
To deploy this sample app, create a new custom integration app and set the ACCESS_TOKEN and APP_SECRET environment variables on your hosting accordingly. Set a value of your choosing for VERIFY_TOKEN, and start your web server. Then go to the Configure Webhooks section of the Edit App dialog and subscribe for the fields mesage_deliveries, messaging_postbacks, message_reads and messages under the Page tab.
To trigger a survey request for a specific user, make a GET request to /start/{user_id}. In a production deployment, you'll want to start survey requests for specific users at well-defined times, and track their responses so you can remind them or re-invite them later.
