API Web Service for EDI X12 Exchange – Discover the Advantages
For over 25 years, we have been working with EDI, integrating systems, and helping companies of all sizes in their digital transformation journey. We have been writing extensively and covering hot topics about EDI integration with e-commerce such as Shopify, Amazon, and other e-commerce platforms, or EDI for drop-ship business, or EDI Integration with Salesforce and other different CRM and ERP systems.
We have extensive knowledge in Electronic Data Interchange (EDI), and we share our knowledge by writing a large number of articles in our Blog; we take up questions from our readers and contacts, related to different EDI topics, including types of EDI messages, EDI Standards and we try to respond to those in our blog.
In this article, there is an important topic I want to expand on: it is our EDI2XML API service, to translate EDI to XML (and vice versa) through our Http/https/httpss REST Web Service; This service, now available as Version 2.0, has gained significant traction among CTOs, integrators, and developers. With major improvements to security (OAuth2), performance, and documentation, the upgraded version is ideal for integration projects using SOA (or service-oriented architecture) or ESB (enterprise service bus).
What Is EDI2XML Web Service and How Does It Work?
EDI2XML Web Service is an HTTP/HTTPS/HTTPSS service running over the internet, on EDIXML own platform that is capable of receiving HTTP/HTTPS/HTTPSS requests to translate EDI messages to XML, and XML messages (based on EDI2XML’s proprietary format) to EDI. The principles of the mechanism of EDI2XML Web Service is schematically illustrated in the figure below.
Is EDI2XML Web Service Right for Your Business or Development Team?
EDI2XML Web Service is for developers and businesses interested in building their own EDI (Electronic Data Interchange) integration flows and programs. Normally, these individuals are capable of interacting with external API and Web Services to translate EDI to XML and XML to EDI, and have the resources and expertise to work with Web Services and HTTP/HTTPS/HTTPSS requests in order to achieve their goals. With Version 2.0, EDI2XML Web Service becomes an even more powerful and reliable option for IT professionals seeking a secure, fast, and flexible solution to handle EDI data exchanges.

What Are the Limitations of the EDI2XML REST API?
Access to our EDI2XML Web Service is unlimited, and there are no limits for http/https calls. EDI2XML format supports currently the most commonly used EDI formats in North America: X12 and EDIFACT. You can check supported EDI transactions listed on our website. In case a transaction you are looking for is not on the list, we can simply just add it and activate into the service at no additional fee.
Understanding the XML Schema for EDI2XML API Integration
When translating from EDI to XML, our EDI2XML Web service will generate a “proprietary” XML format we call it “EDI2XML format”. This is a very structured format where we also provide the corresponding schemas (.xsd) for each transaction, in order to ease developers’ lives.
When translating from XML to EDI, EDI2XML expects a proprietary XML format, which we do provide the schemas (.xsd).
