Short description

With the Amazon SP-API connection, ArbitrageOne reads your sales, fees, inventory and orders directly from Seller Central. Without this connection, ProfitTracker, Purchase Analysis and almost everything around Amazon data won’t work.
ℹ Note: An Amazon Seller Account (Seller Central — for selling on Amazon) is not the same as an Amazon Business Account (B2B purchasing on Amazon Business). Both are connected separately in ArbitrageOne. This article is about the Seller Account.

​
Requirements

  • Active Amazon Seller Central account (not to be confused with Amazon Business)
  • Your account must be Professional (not Individual)
  • Access to the Seller Central region you want to connect

​
Step-by-step guide

​
Step 1: Open the marketplace page

In the menu under Settings → API connections you’ll find your marketplace dashboard with the Amazon card.

​
Step 2: Open the connection page and authorize

Click the Amazon card — the Edit Amazon connection page opens. Here you’ll find the Authorize now button (or Re-authorize if already connected).
⚠ Important: Before that, make sure the processing report language is set to English (US) — otherwise the SP-API can’t read your reports. How to do that: SP-API Processing Report Language.

​
Step 3: Log in to Amazon and authorize

You’ll be redirected to Amazon. Log in with your Seller Central credentials and confirm the permissions for ArbitrageOne.

​
Step 4: Back to ArbitrageOne

After authorization you’re redirected back automatically. The green connected badge appears on the Amazon card and you see a success message.

​
Important notes

  • After a successful connection, data imports start automatically in the background. The first full sync can take a few hours.
  • The processing report language must be set to English (US) — see the linked article above.

​
Common issues

Issue: “Amazon API error” after authorization Solution: Make sure your account is Professional Seller. Try authorization again via Re-authorize. Issue: After logging in to Amazon you land on an empty page Solution: Disable blockers like uBlock Origin or third-party cookie blockers. Use Chrome or Edge in standard mode. Issue: The card still shows “not connected” / no green badge after authorization Solution: Wait 5 minutes (caching), reload the page. If it stays like that, check the processing report language in Seller Central and contact support if needed.
