We've released the new Charges API for increased flexibility to make instant one-time charges against an existing buyer subscription. In just one API call, you can charge buyers for one-off purchases and metered or usage-based add-ons.
Together with our new 'save payment method' user interface, you can now implement marketplace and library style business models with minimum effort while ensuring an optimal user experience.
