I can now get Inventory data from Amazon SP-API for our US and CA marketplace. However, I cannot fetch any data for our UK marketplace even though we have stocks.
I am using the Python SP-API library I've also checked the marketplace ID they used for UK and it is the same as here: https://docs.developer.amazonservices.com/en_UK/dev_guide/DG_Endpoints.html
Is it possible I cannot fetch any data since it is a European region and not a North American Region? What could be the possible problem?
