What is the purpose of a rule input in Appian interfaces?

The purpose of a rule input in Appian interfaces is to pass data into and out of an interface. In Appian, rule inputs serve as parameters that allow you to send data to the interface when it is being rendered and to retrieve any changes made by the user during their interaction with the interface. This mechanism establishes a clear communication path between the interface and the underlying logic or data, ensuring that the right data is displayed, and any modifications made by users are captured effectively.

Using rule inputs enables dynamic interactions within the interface, allowing users to influence how the interface behaves and what data is presented to them based on their inputs or selections. This is essential for building responsive applications that provide tailored experiences for users. By utilizing rule inputs effectively, developers can create user-friendly and interactive interfaces that directly engage with the underlying processes and data within the Appian environment.
