If you would prefer to use header authentication, include your API Key in the HTTPS request by specifying an
header with the value:
You can create a Public API Key on your
Account API Keys
page. Make sure to specify all domains from which this key may be used. Any domain not listed will be rejected by the API. For development purposes, localhost is listed as a domain by default. Make sure to delete this domain before going to production.
To include a public key in your HTTPS request, specify it as the value of anX-Authorization-Public-Keyheader.
If your public key is not authorized, a status code of401will be returned.
