Figma Make can help test an interface with realistic-looking data before a live service is connected. Its practical guide describes a subway tracker whose generated arrival times were mock data, despite a prompt requesting an API connection. It also describes adding CSV upload to a marathon-training dashboard so a designer can supply a controlled dataset. Both approaches support interactive prototyping, but the source of the displayed values determines what the prototype demonstrates: interface behavior or an actual connection to changing external information. The guide also advises caution about connecting third-party APIs through prompts, because that could expose API keys.
