# Flow Response: Success & Error

The **Flow Response** components control what your flow returns when it finishes. Use **Flow Response: Success** to define the payload and HTTP status code returned on a successful run, and **Flow Response: Error** to define what gets returned when the flow encounters a failure. Every API-triggered flow should include both so that callers receive meaningful feedback regardless of the outcome.
