Method description

Returns the top product attributes for a specific query. The product attribute weights are calculated based on user clicks, add-to-carts and purchases and the values are normalized using a linear function.

With segmentation can sent a user attributes list ("key":"value", ...) and number of tries in the request and the API try to return a segment data using this user attributes. If not have results for this user attributes in this number of tries it return the basic query context.

"topAttributes" objects don't have a fixed order and it may change in between requests. Although, values for each attribute are sorted by "weight" in descending order.

Remember that your EB Contextualize configuration could use different fields for the preference calculations, so the ones showing below ("brand" and "gender") are just examples.
