Cannot add Zoho Inventory to Amazon Seller

Cannot add Zoho Inventory to Amazon Seller

Hello,

I am trying to add Zoho Inventory into our Amazon Seller account and I cannot do it. I am following this instructions https://www.zoho.com/inventory/help/marketplaces/amazon.html and when I enter the Developer ID Amazon gives this error

"This developer is not elegible to new authorizations"
Error Code: MD9000

What can I do?
