Establishing a Dialogflow Webhook

Google Cloud Dialogflow creates virtual agents capable of conversing with people to convey and receive information in context. While the Dialogflow UI is quite robust, there are situations that require calculations which can be supplied by a Google Cloud Function when called by a webhook. In this Hands-On Lab, you'll import a Dialogflow CX agent and then modify it to replace a static response with one programmatically output by a Cloud Function and integrated by a webhook.
