Response-time line chart for the account dashboard: a cumulative (running) average response time in DAYS per time bucket across the window. Bucket granularity is auto-selected from the range span (daily ≤30d / weekly ≤180d / monthly ≤730d / else yearly) with the timeline gap-filled. Non-responding / auto-imported / pre-dated responses contribute zero seconds.

Auth: Account — authentication, under the account/dashboard group (role-agnostic). Scope is the caller's company tree: store_id (if given) validated by an ownership check; otherwise all of the caller's stores.

Rate limit: No rate limit.

Request

• Query: store_id (integer, optional) — must belong to the caller's company; omit it to cover all of your locations.
• Query: review_site_id (integer, optional) — filter to one platform; must be an existing review site. When omitted, the caller company's industry review sites apply.
• Query: range_start (string Y-m-d, optional) — defaults to start of 13 months ago.
• Query: range_end (string Y-m-d, optional) — must be ≥ range_start; defaults to end of current month.

Response — { data: [.] } envelope; an array of buckets in chronological order.

• period (string) — bucket key.
• count (number) — cumulative average response time in days, rounded to 2 decimals (named count despite being a days value).

Errors: 422 on validation failure.
