Q:
Is there a way to lookup all reviews of a customer in Amazon's new Product Advertising API?
Using ecs.py, I used to be able to get the reviews of a customer with a query like ecs.CustomerContentLookup(customerId, ResponseGroup='CustomerReviews').
This is now deprecated. Is there an alternative?
Thanks.
