Returns the first successful observation for each requested UTC date, in chronological order. Changes between observations are unobserved. A missing observation has null total and observed_at; a successful empty audience has zero members. History retains today and the preceding 364 UTC dates; older requested dates are gaps. No history is reconstructed before observation began.
Only daily UTC observations are supported. Period data_as_of is always null because samples do not establish continuous freshness; each point carries its actual observed_at. Future, reversed, invalid or longer-than-365-date windows return 422. For the current exact count, use Get audience membership.
Returns 421 when the workspace's organization is served from a different region from the API host. Retry against that workspace's regional host.
