What will I learn?
You will learn how payment network architecture, the four-party model, and regulatory requirements shape every authorization decision. The course covers card authentication technologies including EMV, 3-D Secure, and tokenization, then walks through the full authorization request lifecycle from data capture to issuer response. You will study fraud typology, rule-based controls, and machine learning scoring models used in production environments. Issuer authorization engine design, acquirer integration, and merchant optimization are covered in detail. The course also addresses disputes, chargeback evidence, cross-border complexity, and authorization program governance so you can lead end-to-end authorization strategy.
