Amazon Vendor Central EDI Integration for Wholesale
We build Amazon Vendor Central EDI for Wholesale inside your ERP. Amazon's 850 purchase orders, your 855 acknowledgments, 753/754 routing, 856 ship notices and 810 invoices are read and generated with the EdiFabric .NET library and exchanged directly with Amazon over SFTP, as a connection separate from Direct Fulfillment.

Amazon Vendor Central EDI documents for Wholesale
-
850Purchase order from Amazon. Amazon issues a PO for inventory it will own outright, mapped into a real order in your ERP with Amazon's SKUs matched to yours. -
855Acknowledgment. You confirm quantity, cost and ship date back to Amazon before fulfillment begins. -
753/754Routing request and routing instructions. On a collect shipment Amazon arranges the freight. The vendor sends the 753 with pallet and carton details, Amazon replies with a 754 naming the carrier and pickup, and only then does the 856 go. See EDI 753 and 754 routing. -
856Advance ship notice, to an Amazon FC. Carrier and pack structure have to match what Amazon expects for inbound to its fulfillment center, or the ASN is rejected on arrival. -
810Invoice. Billed to Amazon after shipment, matched line for line against the ASN. -
846Inventory advice. Stock levels reported to Amazon from your own ERP data. -
997Functional acknowledgment. Confirms Amazon received the transaction cleanly. -
824Application advice. Amazon rejecting a document at the application level, with the reason. -
812Credit or debit adjustment. Corrects a billing discrepancy after the fact.
How a Wholesale connection runs once it is live
An Amazon 850 lands in your ERP as an order against your own SKUs. It is accepted or rejected back to Amazon from the same ERP screen that shows system, 3PL and allocated stock, so the decision behind the 855 is made against stock you can see.
Scheduled EDI jobs poll as often as every 10 minutes. Each job's run status and exceptions show on a monitoring dashboard.
How we build Amazon Vendor Central EDI integration inside your ERP
Read and generated inside your ERP
Every X12 file is read and generated inside your ERP using the EdiFabric .NET library, with the mapping in your own code, so Wholesale sits in the same codebase as your other trading partners.
Accept or reject from the stock screen
Amazon purchase orders are accepted or rejected from the same screen that shows system, 3PL and allocated stock, so the 855 matches what you can actually ship.
Every EDI job monitored
Scheduled EDI jobs poll as often as every 10 minutes, and each job's run status and exceptions show on a monitoring dashboard.
Direct connection to Amazon
SFTP straight to Amazon's EDI gateway, with no SPS Commerce or Rithum layer and no per-document cost.
One of three Amazon flows
Wholesale sits alongside Direct Fulfillment and Seller Central in the same ERP, each built as its own flow. See Amazon EDI integration for how they fit together, and EDI transaction sets explained for what each document does.
Amazon Vendor Central EDI in a live ERP
- Native EDI inside the ERP: Every X12 document, including 850, 855, 856, 810, 846 and 997, is read and generated inside the ERP using the EdiFabric .NET library, with the mapping in its own code and no external translation service. Amazon Vendor Central (Wholesale and Direct Fulfillment) and Adorama connect directly over SFTP. Best Buy Optics, Costco Wholesale and Colony Brands run through SPS Commerce. Best Buy Purchasing, Bluestem Brands, QVC, Staples Advantage and Staples the Office Superstore run through CommerceHub (Rithum). BI Worldwide and Mason Companies run through Radial. The ERP uploads its own files to each network's FTP and reads the files the network delivers, and the network validates them and delivers them to the retailer. HSN, Harco Industries, Knocking and Verdi Commerce run on automated file exchange over FTP. Scheduled EDI jobs poll FTP on schedules as short as every ten minutes. Walmart runs through its API. The Walmart API integration imports WFS and seller-fulfilled orders, sends shipment confirmation and tracking back for seller-fulfilled orders, marks WFS orders shipped and invoices them automatically, turns returns into credit memos, and creates WFS inbound shipments. Every job is tracked on a monitoring dashboard.
- Every channel in one order queue: Amazon Vendor Central and Seller Central (SP-API), Walmart, HSN, QVC, Costco, several Shopify storefronts, eBay and direct wholesale accounts land in one system. Vendor Central purchase orders are accepted or rejected back to Amazon from the same screen that shows system, 3PL and allocated stock.
Why Amazon Vendor Central EDI documents get rejected
- A routing request rejected on the appointment slot The appointment slot on the routing request did not match what had actually been scheduled. The discrepancy was diagnosed, the appointment corrected, and the resend was accepted. More on this in EDI 753 and 754 routing.
Amazon Vendor Central EDI questions
How is Wholesale different from Direct Fulfillment?
In Wholesale, Amazon buys the inventory and you ship to its fulfillment center. In Direct Fulfillment, Amazon places dropship orders and you ship straight to the end customer. Different transaction flow, different routing rules.
What is Amazon Vendor Central EDI?
It is how Amazon, as the buyer, exchanges X12 documents with its Vendor Central suppliers. On Wholesale, the connection we run exchanges the 850, 855, 856, 810, 846, 997, 824 and 812, plus the 753 and 754 for routing. Direct Fulfillment is a separate connection on the same account.
How does Amazon Vendor Central integration connect to our ERP?
Directly over SFTP. Every X12 file is read and generated inside your ERP using the EdiFabric .NET library, with the mapping in your ERP's own code.
What does it take to be set up as an Amazon EDI vendor on Wholesale?
A connection to Amazon, which on the account we run is direct SFTP, and a mapping of each Wholesale document to your own item, order and shipment records. Which documents your account must exchange is set by Amazon's implementation guide for your account.
How often are Vendor Central EDI files picked up?
Scheduled EDI jobs poll as often as every 10 minutes, and each job's run status and exceptions show on a monitoring dashboard.
Why do Amazon Vendor Central EDI documents get rejected?
Look for a disagreement between records before assuming the file is broken. The ERP keeps the raw file that was sent next to the parsed result, so the rejected document can be compared with the order and shipment records behind it. On the Amazon connection we run, a routing request was rejected because its appointment slot did not match what had been scheduled. The appointment was corrected and the resend was accepted.
Can this run alongside Direct Fulfillment on the same account?
Yes. We build them as separate integrations because the rules genuinely differ, even on one Vendor Central account.
