이 가이드에서는 에이전트를 보다 동적으로 사용할 수 있도록 웹훅을 사용하는 방법을 보여줍니다.
Cloud Functions는 단순성으로 인해 웹훅을 호스팅하는 데 사용되지만 웹훅 서비스를 호스팅할 수 있는 여러 다른 방법이 있습니다.
또한 이 예시에서 Go 프로그래밍 언어가 사용되지만 Cloud Functions에서 지원되는 모든 언어를 사용할 수 있습니다.
이 가이드의 코드는 수정할 필요가 없습니다.

Read [flow basics](/dialogflow/cx/docs/basics).\n2. Perform [setup steps](/dialogflow/cx/docs/quick/setup).\n3. Perform steps in the [Build an agent using flows](/dialogflow/cx/docs/quick/build-agent) quickstart guide. Steps below continue working on the same agent. If you no longer have that agent, you can [download the agent](/static/dialogflow/cx/docs/data/agent-shirts-1-flow.zip) and [restore it](/dialogflow/cx/docs/concept/agent#export).\n\nCreate the Cloud Function\n-------------------------\n\nCloud Functions can be created with the Google Cloud console ([visit documentation](https://support.google.com/cloud/answer/3465889?ref_topic=3340599), [open console](https://console.cloud.google.com/)).\nTo create a function for this guide:\n\n1. It is important that your Conversational Agents (Dialogflow CX) agent and the function are both in the same project. This is the easiest way for Conversational Agents (Dialogflow CX) to have [secure access to your function](/dialogflow/cx/docs/concept/webhook#cloud-run). To select your project, [go to the project selector](https://console.cloud.google.com/projectselector2/home/dashboard).\n2. Go to the [Cloud Functions overview page](https://console.cloud.google.com/functions/list).\n3. Click **Create Function** , and set the following fields:\n - **Environment**: 1st gen\n - **Function name**: shirts-agent-webhook\n - **Region**: If you specified a region for your agent, use the same region.\n - **HTTP Trigger type**: HTTP\n - **URL**: Click the copy button here and save the value. You will need this URL when configuring the webhook.\n - **Authentication**: Require authentication\n - **Require HTTPS**: checked\n4. Click **Save**.\n5. Click **Next** (You do not need special runtime, build, connections, or security settings).\n6. Set the following fields:\n - **Runtime**: Select the latest Go runtime.\n - **Source code**: Inline Editor\n - **Entry point**: HandleWebhookRequest\n7. Replace the code with the following:\n\n ```python\n // Package cxwh contains an example Dialogflow CX webhook\n package cxwh\n\n import (\n \t\"encoding/json\"\n \t\"fmt\"\n \t\"log\"\n \t\"net/http\"\n )\n\n type fulfillmentInfo struct {\n \tTag string `json:\"tag\"`\n }\n\n type sessionInfo struct {\n \tSession string `json:\"session\"`\n \tParameters map[string]interface{} `json:\"parameters\"`\n }\n\n type text struct {\n \tText []string `json:\"text\"`\n }\n\n type responseMessage struct {\n \tText text `json:\"text\"`\n }\n\n type fulfillmentResponse struct {\n \tMessages []responseMessage `json:\"messages\"`\n }\n\n // webhookRequest is used to unmarshal a WebhookRequest JSON object.

Click **Deploy**.\n\n9. Wait until the status indicator shows that the function\n has successfully deployed.\n While waiting, examine the code you just deployed.\n Code comments describe important details.\n\nCreate the webhook\n------------------\n\nNow that the webhook exists as a Cloud function,\nyou will associate this webhook with your agent.\nTo create the webhook for your agent:\n\n1. Open the [Dialogflow CX console](https://dialogflow.cloud.google.com/cx/projects).\n2. Choose your Google Cloud project.\n3. Select your agent.\n4. Select the **Manage** tab.\n5. Click **Webhooks**.\n6. Click **Create**.\n7. Complete the following fields:\n - **Display name**: shirts-agent-webhook\n - **Webhook URL**: Provide the webhook URL you saved when creating the function.\n - **Subtype**: Standard.\n - All other fields use default values.\n8. Click **Save**.\n\nUse the webhook\n---------------\n\nNow that the webhook is available to the agent,\nyou will make use of the webhook in\n[fulfillment](/dialogflow/cx/docs/concept/fulfillment).\nThe **Order Confirmation** page has an entry fulfillment,\nwhich currently has a static text response.\nTo update the fulfillment to use your webhook:\n\n1. Select the **Build** tab.\n2. Click the **Order Confirmation** page to expand the page on the agent builder graph.\n3. Click the **Entry Fulfillment** field on the page to open the fulfillment panel.\n4. Delete the existing text response under the **Agent says** heading. When you hover the text, the delete *delete* button appears.\n5. Click **Enable webhook**.\n6. Select the `shirts-agent-webhook` option from the **Webhook** dropdown menu.\n7. Enter `confirm` for the **Tag** field.\n8. Click **Save**.\n9. Close the fulfillment panel.\n\nThe deployed webhook code sends a response\nthat creates a\n[parameter](/dialogflow/cx/docs/concept/parameter)\nnamed `cancel-period`.\nUpdate the agent to reference this parameter in the final agent response\nfor the same **Order Confirmation** page:\n\n1. Click the condition [route](/dialogflow/cx/docs/concept/handler) shown with a `true` condition to open the route panel.\n2. Scroll down to the **Fulfillment** section of the route panel, and add the following text response under the **Agent says** heading: `You can cancel your order within $session.params.cancel-period days. Goodbye.`\n3. Click **Save**.\n4. Close the route panel.\n\nTest the agent in the simulator\n-------------------------------\n\nYour agent and webhook are ready to test with the\n[simulator](/dialogflow/cx/docs/concept/console#simulator):\n\n1. Click **Test Agent**.\n2. Enter `I want to buy a large red shirt` and press enter.\n\nSince you provided both a size and color,\nyou gave the agent everything it needs to create a shirt order,\nso it transitions directly to the **Order Confirmation** page.\n\nThe following describes the agent responses:"]]
