Overstock - Configure for Automated Fulfillment

Documentation Team · Updated

DropStream connects your Overstock account to a warehouse management system so orders flow automatically from sale to shipment, and stock levels stay in sync without manual intervention.

What this integration does

  • Imports orders from Overstock into DropStream.
  • Forwards orders to your warehouse management system, with line items mapped by SKU.
  • Posts fulfillment status back to Overstock when the warehouse ships, including tracking numbers and carrier information.
  • Pushes inventory updates from the warehouse to Overstock.

What you’ll need

  • An Overstock account you can sign in to.
  • Your Overstock API Username, API Password, and Warehouse Code.
  • A DropStream account. If you don’t have one yet, contact your DropStream administrator or fulfillment provider.

Setup at a glance

The setup involves work on two sides — Overstock, then DropStream — and the recommended order is:

  1. Get your API credentials (in Overstock) — request your API Username, API Password, and Warehouse Code from Overstock.
  2. Enable API access (in DropStream) — add the store through the Add Connection wizard and enter your Overstock credentials.

Who does what

  • If you manage your own DropStream account, you’ll do every step yourself — switching between Overstock and DropStream as the article order suggests.
  • If a third-party fulfillment provider is configuring DropStream for you, you only need Get your API credentials. Send the resulting credentials to your provider; they handle the rest.

Notes and limitations

  • Request the API Username, API Password, and Warehouse Code from Overstock by emailing integrationanalysts@overstock.com.
  • Configure your Overstock SKUs before connecting: SKUs must match exactly (case-sensitive) and exist in Supplier Oasis before any inventory update.
