Update: Customer favorite filter for reviews API

Date: July 21, 2026

We've enhanced the Get RAP post-purchase items API to support filtering items by customer favorite status. The response now also includes customer favorite status for returned items, making it easier to identify and prioritize customer favorite products when managing Review Accelerator Program (RAP) enrollment opportunities.

What changed

Added

  • Added the isCustomerFavorite filter to the Get RAP post-purchase items API.
  • Added the isCustomerFavorite field to the item-level response payload.

Filter behavior

  • Set isCustomerFavorite to true to return only customer favorite items.
  • Set isCustomerFavorite to false to return only non-customer favorite items.
  • Omit the filter to return all items regardless of customer favorite status.

Response behavior

  • The response now includes isCustomerFavorite for each returned item.
  • When the filter is not specified, the field may contain true, false, or null depending on item data availability.

Why it matters

  • Helps you identify customer favorite items that may benefit from additional reviews.
  • Enables more targeted RAP enrollment decisions by combining customer favorite status with existing filters such as item status, category, price, search, and sorting.
  • Provides additional item insights directly in the API response without requiring separate workflows.

Next steps

  • Review your integration if you want to filter RAP items by customer favorite status.
  • Update any parsers or downstream systems to consume the new isCustomerFavorite response field.
  • Test the new filter in a non-production environment before deploying changes to production.
