Everything on this board is manipulable: drag and edit the data-flow diagram (master data, Front Office Till, and the LiveStore QR Code Web App, each with real payload samples), manage the scenario list as JSON, and try the two scanning interfaces on phone-sized screens.
Drag nodes to rearrange · click a node to edit its name, format and sample payload below · add nodes and links to extend the architecture. Each node carries its exchange format (API, JSON, CSV, DB).
The cards and the JSON below are the same data. Set statuses and notes on the cards, or edit the JSON directly (add, remove, rewrite scenarios) and hit Apply JSON. Import / export as a .json file to share with the team.
Front Office Till β the pop-up is built directly into the Y2 Till Pad; no external app involved. LiveStore β validating the sale launches a separate QR Code Web App with the same kind of scan table, plus the eligibility/batch API calls and CSV hand-off modeled in the diagram above. Scan each physical unit, then Validate & Send.
Freeform notes for the team β meeting takeaways, decisions that don't belong to a single scenario, follow-ups for the next sync.
