ssues Integrating NOL Card Repository with Figma Prototypes

Has anyone here worked on integrating a NOL card repository into interactive Figma prototypes? I'm trying to simulate user flows like card balance checks, recharge, and transaction history, but keeping prototype data consistent across multiple screens is becoming a challenge. I'm also curious whether people are using variables, mock JSON datasets, or plugins to make these transit-card workflows feel more realistic without rebuilding components every time there's a data change. Any recommendations or best practices would be appreciated.
