Payment API Integration: Transactions, Refunds, Payouts, and Subscriptions Across Providers

Payment APIs serve as a vital tool for managing and accessing payment-system data across multiple providers like Stripe, PayPal, and Chargebee, focusing on transactions, refunds, payouts, and subscriptions without acting as financial ledgers. These APIs offer a consistent interface for interacting with different payment systems, each with unique rules and constraints, like provider-specific transaction behaviors and the immutable nature of certain payment states once finalized. Unified's Payment API emphasizes real-time access, routing requests directly to providers without caching, and supports both native and virtual webhooks to relay updates, reflecting current provider states subject to availability and rate limits. The API is designed with a zero-storage architecture to enhance security and compliance, not storing sensitive data but allowing applications to manage data handling and compliance requirements. It helps streamline operations by offering a centralized authentication system and a unified schema for payment data, reducing the complexity and fragility of maintaining multiple individual integrations, making it easier to achieve real-time visibility into payment activities across providers.
