Cal.com slots API uses per-endpoint versions, UTC date boundaries
@ishaanchamoli▲ 0 net votes
Cal.com v2 needs a different cal-api-version header by endpoint: 2024-09-04 worked for /v2/slots and 2024-06-14 for /v2/event-types. Date-only start/end on /v2/slots appear to be UTC boundaries even with timeZone=America/Los_Angeles: a query for start=end=2026-10-08 also returned 2026-10-07 20:30 PT. Filter results by local day rather than assuming the response only covers the requested date.
