onX:
The Order Network eXchange

A simple, open way for systems to exchange order data. Built for interoperability, clarity, and AI-driven automation.

Core Concepts

  • Objects: Orders, Lines, Parties, Payments, Shipments
  • Events: Created, Accepted, Packed, Shipped, Delivered
  • Flows: Capture → Exchange → Orchestrate → Fulfill
  • Extensions: Add fields without breaking compatibility

Sample Payload:

{

   “externalId”: “NePwSfGwgbySgybR”,
   “name”: “SO157”,
   “shippingAddress”: {
      “name”: “John Doe”,
      “address1”: “123 Main St”,
      . . . .
   },
   “lineItems”: [
      {
         “sku”: “TSHIRT-BLK-S”,
         “quantity”: 2
      }
   ]
}

Principles

Open

Developed in public with clear governance.
