API Authentication

The NiceNIC API uses API secret to authenticate requests. You can view and manage your API Secret in the Control Panel.
We strongly recommend that you keep your API secret secure, do not share your secrets in public areas such as GitHub, client code, etc. You can always reset your API Secret by Control Panel.
Authentication to the API is done using the HTTP Authorization header, where you need to specify your Username and API secret, separated by a colon.
All API requests must be made over HTTP. API requests without authentication will also fail.
