Authorization Header


CURL example
curl --location --request GET ''--header 'X-API-KEY: <YOUR_API_KEY>' --header 'Referer: <YOUR_REFERER>'

Note: setting the referer is not required, however, if you want to use the allowed hosts function, make sure to add it. If you have permitted hosts set, and no referer header is set all requests will be blocked.


Prevent unauthorized calls

To prevent your API key from being misused on other websites you have the option to only allow a list of HTTP referrers from using your key.
