Stripe API Integration in Payment Systems represents a formalization of asynchronous event-driven architecture applied to financial transaction processing and state management within distributed systems. The core theoretical mechanism is the coupling of application logic with external payment service provider (PSP) schemas via standardized RESTful interfaces, governed by strict idempotency constraints to ensure data consistency during network failures. This concept exists as a subfield of Payment Gateway Interoperability Theory, where abstract protocols define the semantic exchange of monetary value signals between merchant server environments and global banking infrastructure without exposing sensitive cryptographic keys or transactional state locally.
