EDI vs API: What Growing Businesses Should Really Use?

 Choosing between EDI (Electronic Data Interchange) and API (Application Programming Interface) can feel like picking between two different languages for business communication. If you’re scaling operations or onboarding retail partners like CDW, Target, or Amazon, the wrong choice can cost you time, money, and relationships.


What is EDI?

EDI is a long-standing digital standard used by businesses to exchange structured documents — like purchase orders and invoices — between systems. It’s highly reliable, especially in industries with strict compliance needs.

What is API?

API is a newer, flexible way for applications to communicate in real time. APIs are fast, customizable, and widely used in modern SaaS tools and platforms. But they often require custom development and come with hidden complexity for B2B compliance workflows.

When to Choose EDI

  • You sell to large retailers (CDW, Target, Amazon, etc.)
  • You want label compliance (GS1/UCC-128)
  • You use QuickBooks or Sage and need automation
  • You don’t want to build a custom integration team

When to Use API (or Combine It with EDI)

  • You already have an in-house dev team
  • You want fast data exchange between internal systems
  • You’re building a custom app that talks to your supply chain

Conclusion: What Should You Use?

If you’re growing and selling B2B, EDI is still your foundation. APIs can enhance your internal agility, but for order automation, retailer compliance, and scalable workflows, EDI wins on reliability and cost.

FAQs

Is API replacing EDI?

No. API adds speed and flexibility, but most B2B workflows still rely on EDI due to standardization and compliance requirements.

Yes. ActionEDI supports hybrid integration so you can use APIs internally and EDI for trading partner compliance.
