A client application can be configured to render user interface cards, based on card data provided by a remote card engine. An API Response as Card (ARC) engine can intercept a communication between the client application and the card engine, and determine that the communication is associated with another backend system. The ARC engine can request that the backend system perform an account action associated with a user account. The ARC engine can provide information derived from a response from the backend system, reflecting a result of the account action, to the card engine. The card action can generate card data associated with the result of the account action performed by the backend system, and the client application can use the card data to render and display a corresponding card, even if neither the client application nor the card engine are natively configured to interface with the backend system.
