Use API Keys with Maps Static API

Google Maps Platform products are secured from unauthorized use by restricting API calls to those that provide proper authentication credentials. These credentials are in the form of an API key - a unique alphanumeric string that associates your Google billing account with your project, and with the specific API or SDK.

This guide shows how to create, restrict, and use your API key for Google Maps Platform.

Before you begin

Before you start using the Maps Static API, you need a project with a billing account and the Maps Static API enabled. To learn more, see Set up in Cloud console.

Creating API keys

The API key is a unique identifier that authenticates requests associated with your project for usage and billing purposes. You must have at least one API key associated with your project.

To create an API key:

Console

  1. Go to the Google Maps Platform > Credentials page.

    Go to the Credentials page

  2. On the Credentials page, click Create credentials > API key.
    The API key created dialog displays your newly created API key.
  3. Click Close.
    The new API key is listed on the Credentials page under API keys.
    (Remember to restrict the API key before using it in production.)

Cloud SDK

gcloud alpha services api-keys create \
    --project "PROJECT" \
    --display-name "DISPLAY_NAME"

Restricting API keys

Google strongly recommends that you restrict your API keys by limiting their usage to those only APIs needed for your application. Restricting API keys adds security to your application by protecting it from unwarranted requests. For more information, see API security best practices.

In addition to restricting your API keys, you should sign requests for this API. For more information, see API security best practices.

To restrict an API key:

Console

  1. Go to the Google Maps Platform > Credentials page.

    Go to the Credentials page

  2. Select the API key that you want to set a restriction on. The API key property page appears.
  3. Under Key restrictions, set the following restrictions:
    • Application restrictions:
      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 address translation (NAT), this would typically correspond to your machine's public IP address.
    • API restrictions:
      1. Click Restrict key.
      2. Select Maps Static API from Select APIs dropdown. If the Maps Static API is not listed, you need to enable it.
  4. To finalize your changes, click Save.

Cloud SDK

List existing keys. 

gcloud services api-keys list --project="PROJECT"

Clear existing restrictions on existing key. 

gcloud alpha services api-keys update "projects/PROJECT/keys/KEY_ID" \
    --clear-restrictions

Set new restrictions on existing key. 

gcloud alpha services api-keys update projects/PROJECT/locations/global/keys/KEY_ID \
    --api-target=service=static-maps-backend.googleapis.com
    --allowed-ips="IP_ADDRESS"

Adding the API key to your request

You must include an API key with every Maps Static API request. In the following example, replace YOUR_API_KEY with your API key.

https://maps.googleapis.com/maps/api/staticmap?center=Z%C3%BCrich&zoom=12&size=400x400&key=YOUR_API_KEY

HTTPS is required for requests that use an API key.

What's next

Maps Static API requests should also use a digital signature.
