A company builds a canvas app that users use to enter customer feedback.

Add the prompt to the app: Data. Access the prompt results: Predict().

A preexisting custom prompt is added to a canvas app through the Data pane, in the same general way that a connector or AI model is added as an application data source. Adding it as media, a control, or a variable would not register the prompt as a callable app resource. After it is available in the app, Power Fx invokes it by using the prompt ' s Predict method and passes the current input values required by the prompt. The returned record contains the generated result, which can be assigned to a variable, collected, displayed in a control, or used in later formulas. The call should normally be placed in an event such as a button ' s OnSelect property so that it runs only when intended. Makers should also handle blank inputs and prediction errors and should avoid unnecessarily repeated calls because AI consumption is metered. Microsoft Learn identifies consuming prompts in apps and adding inputs to prompts as AB-410 objectives and documents calling a prompt from Power Apps through Power Fx.
