Sell on Amazon Vendor Central Overview

Updated 3 months ago

Please read first! For information about this function in Sellercloud's original interface, download this file.

Note: The instructions here are for Vendor Central (US). 


Vendor Central is an Amazon program for qualified vendors to become suppliers of merchandise to Amazon. You, as the supplier, will ship the order to Amazon. 

Sellercloud integrates with Vendor Central for Order Download and the Order Acknowledgement. Information on requesting routing and shipping orders can be found here: Vendor Central Shipping Workflow

Amazon's EDI Self-Service Setup Guide has more information about Vendor Central self-service setup. This is a good reference to use if you have issues during your setup. 

After signing into Vendor Central here, go to EDI > Self Service Setup. If you have not started your EDI integration, you must complete the Basic Setup Survey. If so, click Get Started Here under the "Welcome..." message.


Basic setup survey 

  1. Welcome
    • Read the page and click continue 
  2. External IDs and Measurement Code Types
    • Product Identification Code: Vendor SKU
    • Measurement Type: EA
  3. Identifiers
    • Sender/Receiver Identifier type: X12 Sender/Receiver Identifier
    • Your Production Identifiers: 
      • Assuming you do not have EDI Identifiers already, ISA ID Qualifier should be ZZ
      • ISA ID and GS ID can be your phone number. If you have already gotten EDI identifiers for another purpose, you can use those here
    • In Sellercloud, click Settings > choose your company > Toolbox > Vendor Central Settings > General Settings > complete both your company's and Amazon's qualifiers and identifiers
    • On this same Sellercloud page, select the appropriate Freight Type that your Vendor Central account uses: Collect or Prepaid
    • Back in Vendor Central, leave Use different sender/receiver identifiers in test documents unchecked
  4. Test Items
    • Complete the first In Stock Item row. VendorSKU should be your Sellercloud SKU. You can use any existing Sellercloud SKU or create a new SKU in Sellercloud for this purpose. Complete the Net Cost (with a number of your choice) and leave the optional fields blank 
    • Repeat for the Discontinued Item. When confirming orders during testing, you must reject any Discontinued item
    • Leave the Invalid Items rows blank 
    • Fill in one backorder item (Vendor SKU and Net Cost only). When confirming orders during testing, you will be asked to confirm these orders as backordered items
  5. Review
    • Review and click Finish

The next step is setting up a Test Connection - a test and a production connection endpoint. A connection endpoint is the communication path that is used to exchange EDI transactions. We will be using the SFTP protocol for our connection endpoints.


Setting up a test (or production) connection

  2. Under Connection Endpoints > click Add Test Connection (Or, in the case of a production connection, click Add Production Connection.)
  3. Under How do you want to connect to Amazon? select Connect directly to Amazon (AS2, SFTP).
  4. As the Connection Protocol > select SFTP (secure server maintained by Amazon)
  5. You can edit the last part of the Connection Name or leave it as is. The system uses a date/timestamp as the name by default.
