驗證及授權
如要對 API 發出要求，請使用 API 金鑰或用戶端 ID 來驗證應用程式。此外，某些 API 還會要求提供數位簽章。
API 金鑰
您可以使用 API 金鑰來驗證對任何 Google API 發出的要求。如要建立金鑰，請使用與專案 ID 相關聯的 Cloud 控制台專案。使用 API 金鑰可讓您：
在 Cloud 控制台中管理所有 API
透過 Cloud 控制台的 Google 地圖平台指標，存取應用程式的即時使用資料和 30 天的歷來使用資料
用戶端 ID
除了 API 金鑰，您也可以使用用戶端 ID 對任何 API 發出要求；但不包括 Places API、Geolocation API、Roads API、Maps SDK for Android 和 Maps SDK for iOS。

If you have an\nAsset Tracking License, and you want to use the\nPlaces API, then contact the Google Maps APIs Sales\nteam.\n| **Note:** The Places SDK for Android and the Places SDK for iOS are not available for sale, and therefore are not included with the Premium Plan.\n\nAPI provisioning\n----------------\n\nAll of the APIs you purchased in your\n[Google Cloud console](https://console.cloud.google.com/project/_/google/maps-apis/credentials?utm_source=Docs_Credentials)\nproject are enabled.\nTo access your APIs, sign in with your\n[Google Account](/maps/premium/devconsole_access), and then select your\nproject ID, which starts with **Google Maps APIs for Business or Google Maps for Work or Google Maps**.\nBoth your account and project ID are in your welcome letter.\n\nAuthentication and authorization\n--------------------------------\n\nTo make requests to our APIs, you must authenticate your application with either\nan API key or your client ID. In addition, requests for some APIs also require\ndigital signatures.\n\n### API key\n\nYou can use an API key to authenticate requests to any of our APIs. To create\nyour key, you'll use the Cloud console project associated with\nyour project ID. By using an API key, you can:\n\n- Manage all of your APIs in the Cloud console\n\n- Access real-time usage data and 30-days of historical usage data for your\n application in the Cloud console Google Maps Platform\n Metrics\n\n### Client ID\n\nInstead of an API key, you can use your client ID to make requests to any of the\nAPIs *except* the following: Places API,\nGeolocation API, Roads API,\nMaps SDK for Android, and Maps SDK for iOS.\n\nWith your client ID, you can:\n\n- Manage your Client ID and access your private *URL signing secret*,\n or cryptographic key, in the Cloud console.\n\n- Access real-time usage data and 30-days of historical usage data for your\n application from the\n [Cloud console Metrics](https://console.cloud.google.com/google/maps-apis/metrics) page.\n\n For a client ID, a label of the following format will be used:\n `project_number:\u003cYOUR_PROJECT_NUMBER\u003e`.\n- Add the `channel` parameter to requests so you can view more detailed usage\n reports.\n\n#### Where to manage your Client ID in the Google Cloud console\n\nThe Premium Plan Client ID management functionality is available\nin the\n[Cloud console](https://console.cloud.google.com/project/_/google/maps-apis/credentials?utm_source=Docs_Credentials) at the bottom of the\nGoogle Maps Platform Credentials page, in the **Client ID** section. \n\nFurther client ID management tasks, including URL authorization and client ID signing secret\nmanagement, can be accessed on the separate\n[Client ID page](https://console.cloud.google.com/project/_/google/maps-apis/clientid), by clicking the\nedit **edit** icon at the far right of the\n**Client ID** section.\n\n### Digital signatures\n\nIn addition to an API key or client ID, requests to some APIs also require a\nunique digital signature to access the quota and features of your\nPremium Plan. You can generate digital signatures using the private\n*URL signing secret*, or cryptographic key, provided in your Welcome letter\n(and available in the Cloud console). Specifically, you'll need\nto use digital signatures if you use:\n\n- **A client ID** with the web service APIs,\n Maps Static API, or\n Street View Static API\n\n- **An API key** with the Maps Static API or\n Street View Static API\n\n### For more information\n\nFor detailed instructions on using an API key or client ID, and generating\ndigital signatures, see the\n[Premium Plan Authentication Overview](/maps/premium/authentication/overview).\n\nFAQs\n----\n\nIf you have questions about Google Maps Platform, see our frequently asked\nquestions (FAQs):\n\n- [General FAQ](/maps/faq)\n- [Premium Plan FAQ](/maps/premium/faq)\n\nGetting help\n------------\n\nAs a Google Maps Platform Premium Plan customer, you can access the\nCloud console, where you can find support contact information and\naccess exclusive tools and resources.
