Get review volume and rating for each of the last 13 complete months (from the start of the month 13 months ago to the end of last month), one row per month, oldest first. range_start and range_end don't change the window, but if sent they must be valid Y-m-d dates.

Prerequisites: a bearer token. Optional: store_id and review_site_id.

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).
