Payment Gateway Integration
A unified payment gateway that abstracts the complexity of integrating with multiple payment providers. The system supports credit cards, bank transfers, digital wallets, and cryptocurrency payments across 40+ currencies, providing businesses with a single API to manage all their payment needs.
The 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.
Our Solution
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.
The Result
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.
