Get the response rate over time: each point is the percentage of the reviews so far that have a response, so the last point matches the response rate in Headline counts for the same filters. The bucket size follows the range: daily up to 30 days, weekly up to 180 days, monthly up to 730 days, yearly beyond. With no dates, the range is the start of the month 13 months ago to the end of this month, so the buckets are monthly.

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).
