Abstract: An inline frame for transactions, or services, via a parent frame from a platform may maintains the same developer interface from the platform and isolating a transaction from the platform. A service provider receives and processes the transaction by requesting the parent frame open an inline frame, and then renders a user interface in the inline frame to, for example, provide additional transaction-based data or receive an account credential. The inline frame may appear to users as part of the parent frame. However, due to the user interface being rendered in the inline frame, the parent frame and the user interface are in different domains, and the platform or the parent frame cannot receive or surface data rendered or provided in the inline frame. The service provider server notifies the platform when the transaction is complete, allowing the service provider server to maintain loss liability without surfacing sensitive information.
