The Nadles User Portal includes a built-in API that allows you to programmatically access user portal data directly from within the user portal. This API is ideal for customizing user experiences, building custom dashboards, or integrating client-side tools that require user-specific information. You can use this API directly in JavaScript injected into user portal pages. All requests are scoped to the currently logged-in user, and no additional authentication is required when used within the portal environment.
