Payment stories

A small diagram told as two stories: the happy path in three phases, and a declined card in its own file. Press Play, step through, or click a step to jump to it. Switch to Sequence or Story for the same story in another form.

How a card payment moves through the system. Pick a scenario on the bar under the diagram and press play. Each one is a short story about what happens to a single request.
