The DirectIQ API uses API keys and API secrets to authenticate requests. You can find your API key and API secret on API Keys page.
If you have not registered in DirectIQ yet, you can do it here.
Important! Keep your API key and API secret secure. Do not share them in publicly accessible areas.
Authentication to the DirectIQ API is performed via HTTP Basic Auth. Provide your API key as the basic auth username value, and API secret as a password. You can also authenticate using the header: -H "Authorization Basic ClientApiKey:ClientApiSecret as base64".
