InterFAX Node.js Library

A Node.js wrapper for the InterFAX REST API for sending and receiving faxes. This library, version 0.8.4, supports both promises and callbacks, and allows sending faxes via file paths or URLs. It is transpiled to ES5 for backward compatibility and works with Node 4+. Key differentiators include simple setup with environment variables or direct credentials, support for over 20 file types, and access to account balance and fax management endpoints.
