# GS1 EDI Integration: X12 & EANCOM

APIWORX maps GS1-compliant EDI documents directly to your ERP, ecommerce platform and 3PL, so your team stops rekeying orders and chasing chargebacks.

## What GS1 EDI covers

GS1 publishes the GS1 EDI standards (https://gs1.org/edi) and guidelines that retail and consumer goods partners use to exchange business documents. In North America that means the GS1 US (https://www.gs1us.org/) guidelines for ANSI X12 (formerly VICS EDI). Internationally it means GS1 EANCOM (https://gs1.org/eancom/latest), GS1's subset of UN/EDIFACT, along with GS1 XML (https://gs1.org/standards/gs1-xml/3-0).

## EDI documents we integrate

| X12 | Document | What it does |
| --- | --- | --- |
| 850 | Purchase Order | Brings retailer orders straight into your ERP |
| 855 | PO Acknowledgment | Confirms quantities, prices and ship dates back to the buyer |
| 860/865 | PO Change | Handles buyer-initiated changes without manual edits |
| 856 | Advance Ship Notice | Sends carton-level shipment detail tied to SSCC labels |
| 810 | Invoice | Bills accurately against the PO and ASN |
| 846 | Inventory Advice | Shares available stock with retailers and marketplaces |
| 852 | Product Activity | Pulls sell-through and on-hand data from retail partners |
| 940/945 | Warehouse Ship Order/Advice | Connects orders and confirmations with your 3PL |
| 997 | Functional Acknowledgment | Confirms every document was received and accepted |

## Why GS1 EDI breaks, and how we prevent it

Most retailer chargebacks trace back to a late or inaccurate 856 ASN, a GS1-128 label that does not match it, or an invoice that does not reconcile. We build validation into each flow so problems are caught before a document leaves your system.

- GTIN and GLN check-digit validation on every inbound and outbound document
- SSCC labels generated from the same data as the 856
- Partner-specific rules from each retailer's EDI guide and routing guide
- 997 tracking and alerts when a document is rejected
