What is EDI2XML REST API?

The EDI2XML Web Service is an HTTP-based EDI conversion REST API that automatically detects incoming message formats and performs seamless translations between EDI (X12), XML, and JSON. Built on 25 years of EDI expertise, this cloud-based service eliminates the complexity traditionally associated with EDI integration.

Unlike conventional EDI software that requires specialized knowledge and extensive setup, EDI2XML operates entirely over the internet, processing secure HTTP requests to translate:

EDI messages (X12, EDIFACT) into XML or JSON formats
XML or JSON (based on EDI2XML’s proprietary schema) into EDI
Automatic format detection for incoming messages
Bi-directional conversion with consistent reliability

The service is designed for developers who want to integrate EDI capabilities into their applications without becoming EDI experts themselves.

What’s New in EDI2XML REST API Version 2.0?

Enhanced JSON Support

Version 2.0 introduces comprehensive JSON support, allowing developers to work with their preferred data format. The API now supports both application/json and application/xml content types, giving you complete flexibility in how you structure your requests and responses.

Key JSON enhancements include:

Send JSON requests and receive X12 (EDI) responses
Send X12 and receive JSON responses based on request parameters
Native JSON parsing and validation
Improved response structure for better programmatic handling

Built-in 997 Functional Acknowledgment

One of the most significant improvements in version 2.0 is the automatic generation of 997 Functional Acknowledgments. Previously, obtaining acknowledgments required separate API calls, but now:

997 acknowledgments are returned automatically with every conversion
No additional API calls required, reducing complexity and latency
X12-formatted acknowledgment strings ready for immediate processing
Streamlined workflow for compliance and audit requirements

Enhanced Security with OAuth2 Authentication

Security takes center stage in version 2.0 with robust OAuth2 implementation:

Token-based authentication replaces simple API key authentication
Refresh tokens generate access tokens valid for one hour
Enhanced access control for production environments
Secure token exchange following OAuth2 best practices
Better audit trails and access monitoring capabilities

Developer-Focused Improvements

Version 2.0 includes numerous enhancements specifically designed for developer productivity:

Faster response times through optimized processing
Clearer API payloads with improved error handling
Updated XML schemas for better validation
Enhanced documentation with more code examples
Cross-platform Java client for rapid integration
