Challenge
Businesses operating across multiple markets needed to integrate with different payment providers for each region, leading to complex codebases, inconsistent error handling, and difficulty in reconciling transactions across providers.
Approach
We designed a provider-agnostic payment abstraction layer built on Java and Spring Boot, deployed on AWS. The gateway normalizes requests and responses across providers, handles automatic failover, and provides real-time transaction monitoring with comprehensive webhook support.
Outcomes
- The gateway drastically reduced integration time for new payment methods.
- It supports multiple currencies with automatic conversion, high-availability architecture, and provider-agnostic failover for reliable transaction processing.
