Stripe Fundamentals Practice Exam

On-session payments happen when the customer is actively present in the payment flow and completes the payment during that session, typically using a browser or in-app flow. This is the defining idea: the payment is made while the customer is engaged in the session, not later.

That makes the statement describing a one-time purchase where the customer uses a browser to complete the payment the best choice. It emphasizes the customer’s active presence and real-time completion of the payment.

The other notions miss a key point. On-session isn’t limited to one-time purchases—it applies whenever the customer is in the session and paying in real time, including certain interactive scenarios. It isn’t restricted to subscriptions, since the core idea is customer presence in the payment flow, not the specific product type. And the idea of a closed network isn’t relevant to distinguishing on-session versus off-session.
