You can define a list of URLs authorized to call our APIs or Maps with an access token. If not specified or empty, the API will default to any URL. URLs can be targeted by matching a prefix or a suffix using the * character. For multiple HTTP referrers, specify one pattern per line.

A few examples: 

  • https://example.com/* will restrict access to all referers starting with https://example.com
  • *.example.com will restrict access to all referers ending with .example.com
  • If you want to allow access for the full domain example.com, you can use *example.com/*
