Contextualize REST API: User Context - Preferences

Method description

Returns the top product attributes for a specific user and session.

The product attribute preferences are calculated based on user clicks, add-to-carts and purchases and the values are normalized using a linear function.

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

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