This integration only works with accounts/instances within the North America region.
If you are outside of the North America region, Amazon Seller Central will not allow you to connect. Please fill out this form to let Amazon's Marketplace Services team know that you would like to use Zapier with regions outside of North America!
Currently, Amazon's policies only allow API access within the region for which a company is registered, and Zapier is registered in North America. It is impossible for Zapier to become registered in the other international regions, due the information that Amazon requires in those regions. For example, their UK region requires bank account information, and their India region requires a VAT and CST number
Please help let Amazon Marketplace Services know that Amazon needs to enable "API-only" access across all their regions.
