Connect Ecommerce to your Amazon Store

This guide walks you through connecting your Amazon Seller account to Ecommerce and configuring the settings that control how your inventory and pricing appear on Amazon. Follow each section in order for the smoothest setup experience.

Before You Begin

Make sure you have the following ready before starting the Amazon integration:

• An active Amazon Seller Central account. You need a Professional selling plan (not Individual) to use the integration.
• Admin or manager-level access in Ecommerce. Only users with permission to change integration settings can complete the authorization.
• A web browser that allows pop-ups. The authorization process opens a new browser window. If pop-ups are blocked, the connection will fail silently.

Note: Ecommerce connects to the Amazon US marketplace by default. If you sell on a different Amazon marketplace, contact Ecommerce support before beginning setup.

Connecting Ecommerce to Your Amazon Store

Connecting Ecommerce to Amazon allows the two systems to communicate. Ecommerce will be able to send your inventory quantities and pricing to Amazon on your behalf. This is a one-time setup step.

Step-by-Step Instructions

1. Navigate to Integration Settings.

   From the Ecommerce Home Page, go to Settings > Integrations Settings > Amazon.

2. Click the "Grant Access" button.

   This opens a new window in your browser that takes you to Amazon's authorization page.

3. Sign in to Amazon Seller Central (if you are not already signed in).

   Use the credentials for the Amazon Seller account you want to connect — not a personal Amazon shopping account.

4. Review the permissions and click "Authorize."

   Amazon will show you what Ecommerce is requesting access to. Review the list, then confirm. This grants Ecommerce permission to manage listings, inventory, and pricing on your behalf.

5. Wait for the redirect back to Ecommerce.

   After you authorize, Amazon sends you back to Ecommerce automatically. You should see a confirmation message indicating the connection was successful. If the window closes or you see an error, try the process again from Step 1.

6. Verify the connection.

   After authorization, return to Settings > Integrations Settings > Amazon. You should see your Amazon Seller ID displayed, confirming the link is active.

What Happens Behind the Scenes

When you click "Grant Access" and authorize on Amazon's site, Amazon sends a secure authorization code back to Ecommerce. Ecommerce uses that code to establish a long-lived connection to your seller account. You do not need to repeat this process unless you revoke access from within Amazon Seller Central.

Troubleshooting the Connection

Click the grant access button to start, this will open a separate window in your browser.

Setup Checklist

Use this checklist to confirm you have completed every step. Work through it from top to bottom.

Connection

• Confirmed you have an active Amazon Professional Seller account.
• Confirmed you have admin or manager access in Ecommerce.
• Navigated to Settings > Integrations Settings > Amazon.
• Clicked "Grant Access" and completed the Amazon authorization.
• Verified that your Amazon Seller ID appears on the integration settings page.

Amazon Settings Overview

Once your Amazon account is connected, the next step is to configure how Ecommerce manages your inventory and pricing on Amazon.

Navigate to: Ecommerce Home Page > Settings > Amazon

This page is divided into two main sections:

• Inventory Settings — Control how Ecommerce determines what is "in stock" and how many units to advertise.
• Pricing Settings — Control price floors and whether Ecommerce sends pricing data to Amazon at all.

Take your time with these settings. Getting them right from the start prevents overselling, order cancellations, and pricing mistakes.

Frequently Asked Questions

How long does it take for changes to appear on Amazon after I save my settings?

Ecommerce sends inventory and pricing updates to Amazon in batches. Most changes appear within 15 to 30 minutes, but it can occasionally take up to a few hours during peak periods.

Can I connect more than one Amazon account to Ecommerce?

Each Ecommerce account connects to one Amazon seller account. If you operate multiple Amazon seller accounts, contact Ecommerce support for guidance.

I changed my Marketplace Inventory Buffer and now many of my listings show out of stock. Is that normal?

Yes. If you raised the buffer, products that previously met the old threshold may no longer meet the new one. This is expected behavior. If too many listings dropped off, consider lowering the buffer slightly.

What happens if my Amazon authorization expires or is revoked?

Ecommerce will stop sending updates to Amazon. You will need to re-authorize by going to Settings > Integrations Settings > Amazon and clicking "Grant Access" again. Your inventory and pricing settings will be preserved — only the connection needs to be re-established.

I use a repricing tool. Should I still set a Minimum Price Threshold?

Yes. Even with Disable Pricing turned on and a repricing tool handling your prices, the Minimum Price Threshold still controls which products Ecommerce sends inventory for. Setting a threshold prevents low-value items from appearing on Amazon at all, which your repricing tool cannot do on its own.

What is the difference between the Marketplace Inventory Buffer and the Inventory Ceiling?

The buffer is a gate: it decides whether a product appears in stock at all. The ceiling is a cap: it limits how many units are shown once the product passes the gate. Both work together to protect you from overselling.

Should I set the Inventory Ceiling to the same value as the Marketplace Inventory Buffer?

You can, but they serve different purposes. A common setup is a buffer of 6 with a ceiling of 4. This means a product must have at least 6 units available to be listed, but only 4 are advertised. This gives you a 2-unit safety margin even after all advertised units sell.
