遷移作業的帳單最佳做法
warning_amber
如果您的 API 使用量夠高，可改用第二層級的價格，就適用這項指引。遷移至較新版本的 API 時，系統也會以不同的 SKU 計費。為避免在轉換當月費用增加，建議您盡可能在月初切換至正式環境中的新 API。這樣可確保您在遷移當月達到最具成本效益的月費方案。如要瞭解定價層級，請參閱定價頁面和定價常見問題。

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)"]]
