Understanding the Foundations of EDI and APIs
Electronic Data Interchange (EDI) is the long-standing method of transmitting structured business documents—such as purchase orders, invoices, and shipping notices—between companies. It relies on global EDI standards like ANSI X12 or EDIFACT to ensure consistency, compliance, and interoperability across systems and industries.
EDI eliminates manual data entry, reducing errors, delays, and labor costs while creating an auditable record of transactions. It provides the dependability required in industries where timing and accuracy are crucial, such as manufacturing, healthcare, and retail.
Application Programming Interfaces (APIs), by contrast, are built for flexibility and real-time responsiveness. They enable systems to communicate directly by sending or retrieving data on demand. Understanding how APIs work is straightforward: they act as digital connectors that allow software applications to share information instantly without manual intervention.
