On rare occasions, when Professional Amazon Sellers go through the process of linking their Amazon accounts to their Helium 10 account so that they can view their data inside their Helium 10 software, they may encounter issues. This article explains the primary issues that can occur and how to solve them.
I. Denied Access to MWS API
If you try to connect your accounts following these instructions, but get the "This token is denied access to MWS API," message, the cause is generally because:
1) you may not yet have established a Professional Seller Account on Amazon, so you need to create one. Amazon only assigns MWS Tokens to its Professional Seller Accounts. Go to Amazon's Seller Central website and create a Professional Seller Account. Then, follow these instructions.
II. Invalid Token
III. Token Already in Use
