BigCommerce - Configure for Automated Fulfillment

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

What this integration does

• Imports orders from BigCommerce into DropStream as soon as they reach the order status you choose to monitor (typically Awaiting Fulfillment).
• Forwards orders to your warehouse management system, with line items mapped by SKU and the customer’s chosen shipping method translated to a code the fulfillment center understands.
• Posts fulfillment status back to BigCommerce when the warehouse ships, including tracking numbers and carrier information.
• Pushes inventory updates from the warehouse to BigCommerce so available quantities reflect real stock.

What you’ll need

• A BigCommerce store you can sign in to as the Store Owner (required for OAuth authorization).
• The ability to create a Store-Level API Account in BigCommerce with V2/V3 API token access.
• A DropStream store configured for BigCommerce. 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 — BigCommerce, then DropStream — and the recommended order is:

1. Get your API credentials (in BigCommerce) — create an API Account, set OAuth scopes, and note the Store Hash, Client ID, Client Secret, and Access Token.
2. Enable API access (in DropStream) — enter the Store Hash, authorize the DropStream app, and choose which order status triggers an import.
3. Configure SKUs — give every BigCommerce product a SKU. They don’t have to match your warehouse SKUs; if they differ, map them with a Listing. Missing SKUs are a common cause of failed fulfillment.
4. Gather shipping methods — map the shipping methods offered at checkout to the codes your fulfillment center uses.
5. (Optional) Enable inventory tracking (in BigCommerce) — turn on tracking so DropStream’s pushed inventory updates take effect.
6. Review order status — confirm orders are flowing end-to-end once the integration is enabled.

Steps 1 through 4 are required. Step 5 is only needed if you want DropStream to keep BigCommerce inventory counts in sync with the warehouse.

Who does what

• If you manage your own DropStream account, you’ll do every step yourself — switching between BigCommerce 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

• The BigCommerce API Account must use a V2/V3 API token, not a legacy account.
• The required OAuth scopes are listed on the Get your API credentials article — granting less will cause the integration to fail at runtime, not at setup.
• The default monitored status is Awaiting Fulfillment. If your store uses a custom workflow, choose the status that signals an order is ready to ship.
• Inventory updates from DropStream only apply when BigCommerce inventory tracking is enabled at the product or variant level.

If something isn’t working, start with Review order status — it walks through the import statuses and what each one means.
