Some systems don't allow for OAuth 2 authentication. To help you call our APIs anyway, you can call our APIs using an API Key to authenticate with.
You can find your API Key in Admin → API IP Whitelist. Once you have obtained it, you can use the API Key in the Request Headers to authenticate.
|Request Header||Header Value|
In curl, this would look something like this:
curl -H "Authorization: api_key XXXXX" -X GET "https://api.eu.customergauge.com/v4.1/ApiFamily/ApiMethod.json"
