Produkty Google Maps Platform są chronione przed nieuprawnionym użyciem przez ograniczenie wywołań interfejsu API do tych, które zapewniają odpowiednie dane logowania. Te dane logowania mają postać klucza interfejsu API – unikalnego ciągu alfanumerycznego, który łączy Twoje konto rozliczeniowe Google z projektem oraz z konkretnym interfejsem API lub pakietem SDK.
Z tego przewodnika dowiesz się, jak utworzyć klucz interfejsu API Google Maps Platform, ograniczyć jego użycie i z niego korzystać.
Zanim zaczniesz
Zanim zaczniesz korzystać z interfejsu Distance Matrix API, musisz mieć projekt z kontem rozliczeniowym i włączonym interfejsem Distance Matrix API. Więcej informacji znajdziesz w artykule Konfigurowanie w konsoli Google Cloud.
Tworzenie kluczy interfejsu API
Klucz interfejsu API to unikalny identyfikator używany do uwierzytelniania żądań powiązanych z projektem na potrzeby wykorzystania i rozliczania. Z projektem musi być powiązany co najmniej 1 klucz API.
Zdecydowanie zalecamy ograniczenie kluczy interfejsu API tylko do tych interfejsów API, które są potrzebne do działania aplikacji. Ograniczenie dostępu do kluczy interfejsu API zwiększa bezpieczeństwo aplikacji, chroniąc ją przed nieuzasadnionymi żądaniami. Odpowiadasz finansowo za opłaty spowodowane nadużywaniem kluczy interfejsu API bez ograniczeń.
Aby dowiedzieć się więcej, zapoznaj się ze sprawdzonymi metodami zapewniania bezpieczeństwa interfejsu API.
W każdym żądaniu wysyłanym do interfejsu Distance Matrix API musisz podać klucz interfejsu API. W tym przykładzie zastąp YOUR_API_KEY swoim kluczem API.

These credentials are in the form of\nan API key - a unique alphanumeric string that associates your Google billing account with your\nproject, and with the specific API or SDK.\n\nThis guide shows how to create, restrict, and use your API key for Google Maps Platform.\n\nBefore you begin\n----------------\n\nBefore you start using the Distance Matrix API, you need a project with a billing account and the\nDistance Matrix API enabled. To learn more, see [Set up in Cloud console](/maps/documentation/distance-matrix/cloud-setup).\n\nCreating API keys\n-----------------\n\nThe API key is a unique identifier that authenticates requests associated with your project for\nusage and billing purposes. You must have at least one API key associated with your project.\n\nTo create an API key:\n\n### Console\n\n1. Go to the **Google Maps Platform \\\u003e Credentials** page.\n\n [Go to the Credentials page](https://console.cloud.google.com/project/_/google/maps-apis/credentials?utm_source=Docs_CreateAPIKey&utm_content=Docs_distance-matrix-backend)\n2. On the **Credentials** page, click **Create credentials \\\u003e API key** . \n The **API key created** dialog displays your newly created API key.\n3. Click **Close.** \n The new API key is listed on the **Credentials** page under **API keys** . \n (Remember to [restrict the API](/maps/api-security-best-practices#restricting-api-keys) key before using it in production.)\n\n### Cloud SDK\n\n```bash\ngcloud services api-keys create \\\n --project \"\u003cvar translate=\"no\"\u003ePROJECT\u003c/var\u003e\" \\\n --display-name \"\u003cvar translate=\"no\"\u003eDISPLAY_NAME\u003c/var\u003e\"\n```\n\nRead more about the\n[Google Cloud SDK](https://cloud.google.com/sdk)\n,\n[Cloud SDK installation](https://cloud.google.com/sdk/docs/install)\n, and the following commands:\n\n- [`gcloud services api-keys create`](https://cloud.google.com/sdk/gcloud/reference/services/api-keys/create)\n\nRestricting API keys\n--------------------\n\nGoogle strongly recommends that you restrict your API keys by limiting their usage to those only\nAPIs needed for your application. Restricting API keys adds security to your application by\nprotecting it from unwarranted requests. **You are financially responsible for charges caused by abuse of unrestricted API keys.** For more information, see\n[API security best practices](/maps/api-security-best-practices#restrict_apikey).\n\n| When restricting an API key in the Cloud console, **Application restrictions** override any APIs enabled under **API restrictions**. Follow best practices by creating a separate API key for each app, and for each platform on which that app is available.\n\nTo restrict an API key:\n\n### Console\n\n1. Go to the **Google Maps Platform \\\u003e Credentials** page.\n\n [Go to the Credentials page](https://console.cloud.google.com/project/_/google/maps-apis/credentials?utm_source=Docs_RestrictAPIKey&utm_content=Docs_distance-matrix-backend)\n2. Select the API key that you want to set a restriction on. The API key property page appears.\n3. Under **Key restrictions**, set the following restrictions:\n - Application restrictions:\n 1. To accept requests from the list of web server IP addresses that you supply, select **IP addresses (web servers, cron jobs, etc.)** from the list of **Application restrictions** . Specify one or more IPv4 or IPv6 address, or subnet using CIDR notation. The IP addresses must match the source address the Google Maps Platform servers observe. If you use [network\n address translation (NAT)](https://en.wikipedia.org/wiki/Network_address_translation), this would typically correspond to your machine's *public* IP address.\n - API restrictions:\n 1. Click **Restrict key**.\n 2. Select **Distance Matrix API** from **Select APIs** dropdown. If the Distance Matrix API is not listed, you need to [enable](/maps/documentation/distance-matrix/cloud-setup#enabling-apis) it.\n4. To finalize your changes, click **Save** . \n\n### Cloud SDK\n\n\nList existing keys. \n\n```bash\ngcloud services api-keys list --project=\"\u003cvar translate=\"no\"\u003ePROJECT\u003c/var\u003e\"\n```\n\n\nClear existing restrictions on existing key. \n\n```bash\ngcloud services api-keys update \"projects/\u003cvar translate=\"no\"\u003ePROJECT\u003c/var\u003e/keys/\u003cvar translate=\"no\"\u003eKEY_ID\u003c/var\u003e\" \\\n --clear-restrictions\n```\n\n\nSet new restrictions on existing key. \n\n```bash\ngcloud services api-keys update projects/PROJECT/locations/global/keys/KEY_ID \\\n --api-target=service=distance-matrix-backend.googleapis.com\n --allowed-ips=\"\u003cvar translate=\"no\"\u003eIP_ADDRESS\u003c/var\u003e\"\n```\n\nRead more about the\n[Google Cloud SDK](https://cloud.google.com/sdk)\n,\n[Cloud SDK installation](https://cloud.google.com/sdk/docs/install)\n, and the following commands:\n\n- [`gcloud services api-keys update`](https://cloud.google.com/sdk/gcloud/reference/services/api-keys/update)\n- [`gcloud services api-keys lookup`](https://cloud.google.com/sdk/gcloud/reference/services/api-keys/lookup)\n- [`gcloud services api-keys list`](https://cloud.google.com/sdk/gcloud/reference/services/api-keys/list)\n\nAdding the API key to your request\n----------------------------------\n\nYou must include an API key with every Distance Matrix API request. In the following example,\nreplace `YOUR_API_KEY` with your API key.\n`https://maps.googleapis.com/maps/api/distancematrix/json?origins=Seattle&destinations=San+Francisco&key=`YOUR_API_KEY\n\nHTTPS is required for requests that use an API key.\n| **Note:** When using Web Services, all special characters inside the parameters must be URL encoded. URLs must be properly encoded to be valid and are limited to 2048 characters for all web services. Be aware of this limit when constructing your URLs. Different browsers, proxies, and servers may have different URL character limits as well."]]
