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
Authorization
api_key XXXXX


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"
