We highly recommend you to authenticate using OAuth 2 authentication. However, some systems don't allow for that. 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"
