The very first step that should be taken after adding a new marketplace is to connect the Selling Partner API.

What is the Selling Partner API?

The SP-API is a connection to Amazon that allows Seller Labs to securely access your orders, shipments, payments, and more. It automates data retrieval, saving time and improving efficiency so you can focus on growing your business.

Why this connection is important?

The SP-API is essential for Seller Labs to function properly. Without it:

  • We can’t pull in your sales data.

  • We can’t track orders in our tools.

  • We can’t generate helpful charts for your business.

Connecting the SP-API ensures your data is accurate and up to date, allowing you to get the most out of Seller Labs.

How to connect/reconnect the Selling Partner API?

After you first connected your marketplace, you should see the next screen where please click the Complete Connection button:

You will be redirected back to Amazon Seller Central where please click the Allow button:
