Payment API Solutions: The Integration Brief

A payment integration often starts with a developer asking for an API key. That is a technical requirement, but it is not yet a complete business brief. The team still needs to know what customers will buy, which payment route is intended, when an order becomes deliverable and who resolves exceptions. WATADCASH’s gateway guidance asks businesses to consider activity, customer markets and the payment flow. Writing those answers first can save repeated redesign later.
