How the exchange works
How ecommerce platforms exchange business documents
Marketplaces and storefront platforms mostly exchange orders, inventory and tracking through their own published APIs, while online retailers that use drop-ship suppliers often use EDI. Timing matters most: if stock levels or shipment status fall behind, the channel oversells, cancels orders or penalizes the seller.
| Document | What it does in this relationship |
|---|---|
| APIs | Listings, orders, inventory and fulfilment updates through the platform’s own REST API. |
| EDI 850Purchase Order | A drop-ship order from an online retailer, with the end customer’s ship-to address. |
| EDI 856Advance Ship Notice | Shipment confirmation with carrier and tracking number, so the customer can follow the delivery. |
| EDI 846Inventory Inquiry/Advice | Inventory feed that keeps the online offer in line with what you can actually ship. |
| EDI 810Invoice | The invoice to the online retailer for each drop-shipped order. |
What onboarding a new ecommerce platforms partner usually involves
- Set up API access from your seller or vendor account and agree the SKU and listing mapping.
- Decide how often inventory and prices are sent, and how cancellations and returns flow back.
- Test orders end to end, including split shipments and tracking updates, before opening the channel.
