CyberSource REST Client SDK

The official Node.js SDK for the CyberSource REST API (version 0.0.79) allows merchants to process payments, manage transactions, and access CyberSource services from Node.js applications. It requires Node.js 14.21.3 or higher. The SDK supports multiple authentication methods: HTTP Signature (deprecated), JWT with P12 certificate, and JWT with Shared Secret (recommended migration path from HTTP Signature, enabling Message Level Encryption). It also supports MetaKey for portfolio-level management. Key differentiators: official CyberSource SDK, support for JWT Shared Secret, MetaKey functionality, and clear deprecation guidance for HTTP Signature.
