Amazon

Amazon is the most common first connection for Gierd users, and the most important one to get right. It serves as the primary pricing anchor — the Pricing Engine calculates prices for Amazon first, then syncs those decisions to your other connected marketplaces.

What data syncs

Once connected, Gierd syncs the following data from your Amazon account:

Data	Description
Orders	All marketplace orders, used to populate Sales and Finance
Inventory	Current stock levels per SKU, updated continuously
Listings & offers	Listing and offer details, used in the Pricing Engine and to fill your Catalog
Fees	Per-SKU marketplace fees (referral, FBA, etc.), used in pricing calculations
Marketplace payouts	Payouts from Amazon, used in the Finance ledger

Before you begin

You’ll need:

• An active Amazon Seller Central account
• Your Seller ID (also called Merchant Token) — found in Seller Central under Settings → Account Info
• Admin access in both Gierd and Seller Central

Connect Amazon

1. Open Connections

   In Gierd, go to Connections in the left sidebar. Click Add Connection, then select Amazon.

2. Fill out the connection form

   Enter the following details:

   • Name — a label for this connection (e.g., “Amazon US”)
   • Seller Name — your store name as it appears in Seller Central
   • Seller ID — your Amazon Seller ID, found in Seller Central under Settings → Account Info → Merchant Token
   • Region — the Amazon region for your account (defaults to US)
   • Report Type — select FBA, FBM, or both, depending on your fulfillment model

3. Authorize Gierd in Amazon

   Click Authorize. You’ll be redirected to Amazon’s consent page. Sign in with your Seller Central credentials if prompted, then click Confirm to grant Gierd access to your account.

   Caution

   Make sure you’re authorizing from the correct Seller Central account — especially if you manage multiple accounts. Check the account name displayed on the authorization page before confirming.

4. Save the connection

   After authorizing, you’ll be returned to Gierd. Review the connection details and click Save to complete setup. Gierd begins syncing your Amazon data.

   Note

   If you have multiple Amazon seller accounts, repeat this process for each one. Each account requires its own connection.

Amazon as the primary pricing anchor

The Pricing Engine treats Amazon as the anchor marketplace. Here’s what that means in practice:

• Prices are calculated for Amazon first. Every pricing decision — whether from a strategy, rule, or floor — starts with Amazon.
• Other channels inherit from Amazon. When the engine sets a price on Amazon, it syncs that decision to your other connected marketplaces (eBay, Walmart, Back Market) with channel-specific adjustments applied.
• Repricing is bidirectional. Unlike legacy repricers, Gierd raises prices when market conditions allow — not just lowers them. The engine protects your margin floor while actively pursuing the Buy Box.

For more on how pricing decisions are made, see Pricing.

After connecting

Once connected, Gierd begins syncing your Amazon data in the background. Check connection status from Connections → Amazon in Gierd.

Troubleshooting

Authorization failed

If you see “Authorization failed” after being redirected back from Amazon:

• Make sure you completed the authorization on Amazon’s consent page rather than canceling or closing it
• Verify you authorized using the correct Seller Central account
• Try again from the beginning — go to Connections → Add Connection → Amazon

Connection failed with an error

If you see “Sorry, there was an issue connecting”:

• Check that your Seller ID matches the account you authorized in Amazon — a mismatch is a common cause
• Ensure you’re using a Seller Central account (not Vendor Central)
• Delete the failed connection and start over

If the issue persists, contact support with the connection name and the error message shown.

Data not appearing after connecting

After saving the connection, Gierd begins syncing your data in the background. Orders and inventory appear first; fee and payout data may take longer as it depends on available reports in Seller Central.

If data is still missing after several hours, go to Connections, find the Amazon connection, and check the connection status for any errors.

Prices aren’t updating on Amazon

Bidirectional repricing requires that:

• At least one Pricing Strategy is active and assigned to your Amazon SKUs
• The connection status shows Connected (not an error state)

If an offer is newly active, the engine will wait 24 hours before taking its first repricing action.
