Conversational Agents (Dialogflow CX) 支持以下代理位置。下表中列出的区域也支持数据存储区代理，但数据存储区使用的区域 ID 与代理区域（如上所列）略有不同。Vertex AI Conversation 中的数据存储区代理支持在数据存储区区域 ID 列中输入值的所有区域。

Check\n documentation for each integration.\n\n- System entity support differs for each\n [language](/dialogflow/cx/docs/reference/language).\n See the\n [system entity limitations](/dialogflow/cx/docs/reference/system-entities#limits)\n for details.\n\n- The\n [APIs Explorer](https://developers.google.com/explorer-help/),\n found on many\n [REST reference documents](/dialogflow/cx/docs/reference/rest),\n only supports the `global` region for API calls.\n\nAvailable regions\n-----------------\n\n| **Important:** The \"[AI/ML Data Location](/terms/data-residency)\" (Data Residency for ML Processing) commitment is only supported in the locations within the US and EU. ML Processing for generative models may occur within any location in the multi-regions when requests are made to regional APIs included within a multi-region. For more details, see the [Vertex AI documentation](/vertex-ai/generative-ai/docs/learn/locations).\n\nConversational Agents (Dialogflow CX) supports the following regions for agent location.\n[Data store agents](/dialogflow/cx/docs/concept/data-store-agent)\nare also supported in the regions listed in the following table, but the region\nIDs used by data stores differ slightly from the agent regions (as listed).\nAll regions with a value entered in the **Data store region ID** column\nare supported by data store agents in [Vertex AI Conversation](/generative-ai-app-builder/docs/agent-intro).\n\nYou can read more about regions used by Google Cloud at\n[Google Cloud regions](/about/locations)\nand\n[Google Cloud geography and regions](/docs/geography-and-regions).\n\nLocation settings\n-----------------\n\nIf your system requires\n[customer-managed encryption keys](/dialogflow/cx/docs/concept/cmek) (often required by government entities or regulated industries),\nyou can use location settings to configure this feature.\n\nLocation settings are shared across the project,\nand each unique location has its own location settings.\n\nOnce settings for a specific location are configured for a project, an immutable\n`dialogflow.googleapis.com/LocationSettings`\n[resource](/asset-inventory/docs/asset-names) is created, and the settings\ncannot change for that location. If you need to change these settings or to\ndelete the resource, you must create a new project.\n\nIf you need to allow your organization's developers to configure agents only in\nspecific locations, you can [set up an organization policy that includes a\nresource locations\nconstraint](/resource-manager/docs/organization-policy/defining-locations-supported-services#dialogflow).\n\nIf you create an agent without editing the location settings,\nthe default settings will be configured for that location,\nand they cannot be changed for the project.\nIn addition, once an agent is created, its location cannot change.\nIn order to change an agent's location,\nyou must\n[export and restore](/dialogflow/cx/docs/concept/agent#export)\nto a new agent with a different location.\n\nThe following location settings are available:\n\n- **Encryption** : This setting controls whether Google-managed or customer-managed encryption keys are used to protect data. The default is Google-managed. You must request access (by contacting your Google representative) to the [customer-managed encryption keys](/dialogflow/cx/docs/concept/cmek) feature to change this setting.\n\nYou can configure location settings in two ways:\n\n- Click **Location settings** from the [agent selector interface](/dialogflow/cx/docs/concept/console#agent).\n- Click the **Edit** button next to the **Location** drop down when [creating an agent](/dialogflow/cx/docs/concept/agent#create).\n\n| **Note:** Currently, you cannot update location settings with the API.\n\nSpecify a region with the API\n-----------------------------\n\nYou must specify a region for all API requests.\n\nFor REST calls, you must do both of the following:\n\n- Provide the region ID for the `location` URL path parameter.\n\n- For the `global` region, use `dialogflow.googleapis.com` for the\n hostname. For all other regions, use `[region-id]-dialogflow.googleapis.com`\n for the hostname.\n\nFor example:\n\n- `dialogflow.googleapis.com/projects/{PROJECT_ID}/locations/global/agents/{AGENT_ID}`\n\n- `us-central1-dialogflow.googleapis.com/projects/{PROJECT_ID}/locations/us-central1/agents/{AGENT_ID}`\n\nFor client libraries, see the\n[client library documentation](/dialogflow/cx/docs/reference/library/overview)\nfor a region configuration option.\n\nYou can find examples in the\n[API quickstart](/dialogflow/cx/docs/quick/api).\n| **Caution:** As described in the [setup documentation](/dialogflow/cx/docs/quick/setup#auth-env), you should use the `GOOGLE_APPLICATION_CREDENTIALS` environment variable to provide your client libraries with credentials. However, if you need to manually provide a credentials file in your code, you need to take one additional step when calling a regionalized endpoint. Set the scope to `https://www.googleapis.com/auth/cloud-platform` when generating your authentication credentials. For example, this is accomplished in Java when creating a `GoogleCredentials` object: \n|\n| ```\n| GoogleCredentials.fromStream(new FileInputStream(\"credential_file\"))\n| .createScoped(\"https://www.googleapis.com/auth/cloud-platform\")\n| \n| ```\n\nCloud logging\n-------------\n\nSee the\n[Cloud logging guide](/dialogflow/cx/docs/concept/logging)\nto control the region in which logs are stored."]]
