I created a new Canadian Amazon affiliate ID three days ago. When I logon to associates.amazon.ca, the store ID appears and seems to be working. However, when I try to add a product to the Repo, I get the following error message:
thanks for your feedback.
This means that your Amazon account is not yet approved for the Amazon Product Advertising API. Please have a look at the conditions under the given link. They should be the same in Canada as in other countries. It may be necessary that three products have to be purchased via your affiliate link, maybe even via the website you have provided in the Amazon account settings.
I hope this information helps you. If you still have questions, please let me know.
