Get the share of reviews from each site, most reviews first. With more than five sites (and no review_site_id) you get the top four plus an Others row. Send both range_start and range_end to count only that window; otherwise the counts are all-time.

Prerequisites: a bearer token. Optional: store_id, review_site_id, and a date range (range_start, range_end, both Y-m-d).

Authentication: Partner or Account token. Without store_id the figures cover every location the token can see; store_id must be inside your own account tree, otherwise 422.

Rate limit: 120 requests per minute, counted per user (the token’s user).
