Amazon Marketplace - Connect Your Store

This article is for whoever connects an Amazon store inside DropStream — a fulfillment provider (3PL) or a merchant who manages their own DropStream account. You’ll add the store through DropStream’s Add Connection wizard.

Amazon uses the Selling Partner API (SP-API), which authorizes through Amazon’s own sign-in (OAuth). There are no API keys, secrets, or “API user” to create — the only thing you choose in DropStream is the marketplace; access is granted by signing in to Amazon and approving DropStream.

What you’ll need

• A DropStream account you can sign in to.
• The Amazon marketplace the store sells in (for example, United States or United Kingdom).
• An Amazon Seller Central account with permission to authorize apps — used for the one-time authorization step. For 3PL setups, this is the merchant’s Seller Central account, and they authorize it themselves (see below).

How DropStream connects to Amazon

Every store connects through the same Add Connection wizard. For the full walkthrough of the wizard’s four steps, see Add a Connection. This article covers only the Store Setup step, where you choose the Amazon-specific settings and authorize.

Choose the marketplace

1. In the Add Connection wizard, work through to the Store Setup step. Choose Create new store, give the store a Name, and select Amazon Marketplace as the Platform. The Amazon settings appear below.

   

2. Select the Marketplace this store sells in. DropStream supports the United States, Canada, Mexico, Brazil, the UK, and the EU, Middle East, India, and Asia-Pacific marketplaces, among others.

   One connection per marketplace. Amazon authorizes access per-marketplace, so each marketplace needs its own DropStream connection, billed individually. For example, France (.fr) and Spain (.es) each require a dedicated connection.

Authorize Amazon

How you authorize depends on whether you’re a fulfillment provider or a merchant managing your own account.

If you’re a fulfillment provider (3PL)

Amazon requires the merchant to authorize their own Seller Central account, so you won’t see an Authorize button — only Send to merchant. Click it, enter the merchant’s email, and DropStream emails them a secure link to authorize Amazon. Once they’ve done so, you finalize the connection. For the full flow, see Send a Store Authorization to a Merchant.

If you manage your own DropStream account (merchant)

Click Authorize, sign in to Amazon Seller Central, and approve access for DropStream. The window closes and returns you to the wizard with the authorization applied.

Import and fulfillment settings

Set these in the Store Setup step (the defaults suit most merchant-fulfilled setups):

Save the connection

When you’re done, click Add connection. (In a 3PL handoff, you save the connection at the Finalize step instead — see the handoff article above.)

Once the connection is added, continue with Configure SKUs, then confirm orders are flowing with Review Order Status.
