如果您的 API 用量足够高，可以采用第二级定价，则此指南适用。迁移到较新版本的 API 时，您还需要为不同的 SKU 付费。为避免在过渡当月增加费用，我们建议您在尽可能接近月初时切换到生产环境中的新 API。这样可确保您在迁移月份达到最具成本效益的月度价格层级。如需了解价格层级，请参阅价格页面和价格常见问题解答。
启用 Places API（新）
如需使用 Places API（新）的功能，您必须先在 Google Cloud 项目中启用 Places API（新）。如需了解详情，请参阅设置您的 Google Cloud 项目。
然后，您必须确保已将 Places API（新）添加到应用使用的 API 密钥中。如需了解详情，请参阅使用 API 密钥。

Functionality varies by region. [Learn more](/maps/comms/eea/faq).\n\nIntroduction\n------------\n\nPlaces API (New) provides improved performance and a new pricing model,\nmaking it worthwhile to update apps that use the Places API (Legacy). For more\ndetails on comparing features, see [Choose your\nAPI](/maps/documentation/places/web-service/choose-api).\n\nUse this guide to understand key differences between Places API (New)\ncompared to Places API (Legacy), along with how to handle necessary changes.\n\n\nBilling best practices for migration\n------------------------------------\n\nwarning_amber\n\nThis guidance applies if your API usage is high enough to\nmove into second-tier pricing. When migrating to a newer version of an API,\nyou're also being billed for a different SKU. To avoid increased costs during the month of\nyour transition, we recommend switching to the new APIs in production as close to the\nbeginning of the month as possible. This will ensure that you reach the most cost-effective\nmonthly pricing tiers during the migration month. For information about pricing tiers,\nsee the [pricing page](/maps/billing-and-pricing/pricing)\nand the [pricing FAQ](/maps/billing-and-pricing/faq).\n\n\u003cbr /\u003e\n\nEnable Places API (New)\n-----------------------\n\nTo use the features of Places API (New), you must first enable\n**Places API (New)** in your Google Cloud project. For more\ninformation, see [Set up your Google Cloud\nproject](/maps/documentation/places/web-service/cloud-setup).\n\nYou then must ensure that you have added **Places API (New)** to the API\nkey used by your app. For more information, see [Use API\nKeys](/maps/documentation/places/web-service/get-api-key).\n| **Note:** If you are using both Places API (Legacy) and Places API (New), we recommend that you create a separate API key for each API version.\n\nGeneral changes\n---------------\n\nSome general changes that apply to multiple APIs include:\n\n- All new APIs support both [API keys](/maps/documentation/places/web-service/get-api-key) and [OAuth](/maps/documentation/places/web-service/oauth-token) tokens as the authentication mechanism.\n- Only JSON is supported as a response format.\n- Field masking is required by Place Details (New), Nearby Search (New), and Text Search (New) to specify which fields you want returned in the response. For more information, see [FieldMask](/maps/documentation/places/web-service/choose-fields).\n- The [Nearby Search (New)](/maps/documentation/places/web-service/nearby-search) and [Text Search (New)](/maps/documentation/places/web-service/text-search) APIs now return the full place details to match the place details returned by [Place Details (New)](/maps/documentation/places/web-service/place-details).\n- The JSON response format for the [Place Details (New)](/maps/documentation/places/web-service/place-details), [Nearby Search (New)](/maps/documentation/places/web-service/nearby-search), and [Text Search (New)](/maps/documentation/places/web-service/text-search) APIs has changed from the format of the existing APIs. For more details, see [Migrate the Places API response](/maps/documentation/places/web-service/migrate-response).\n\nAPI-specific changes\n--------------------\n\nThis section includes the following migration guides for each API:\n\n- [Migrate to Nearby Search (New)](/maps/documentation/places/web-service/migrate-nearby)\n- [Migrate to Text Search (New)](/maps/documentation/places/web-service/migrate-text)\n- [Migrate to Place Details (New)](/maps/documentation/places/web-service/migrate-details)\n- [Migrate to Place Photos (New)](/maps/documentation/places/web-service/migrate-photo)\n- [Migrate to Autocomplete (New)](/maps/documentation/places/web-service/migrate-autocomplete)"]]
