Iamport REST API Client

Node.js SDK for I'amport REST API (v0.4.0, deprecated). This package provides a promise-based client to interact with I'amport payment gateway services, including payment lookup, cancellation, subscription management, and certification. It is the official Node.js SDK but has been deprecated since March 2026. Users are advised to migrate to PortOne V1 REST API or fork the repository. The package ships TypeScript types and supports Node.js >= 0.12.x. Key differentiator: it wraps the full I'amport REST API in a fluent, promise-based interface. However, it is outdated and no longer maintained, with potential security vulnerabilities in dependencies.
