Every calendar in your organization, bookable through one API.

Query a Calendar Group for live availability, then confirm — Vinta resolves the right provider or resource and writes back to every connected calendar.

• One GraphQL endpoint + webhooks for every booking event
• Calendar Groups resolve the right provider or room for you
• Booking codes for single-use, tokenless public scheduling

# POST /graphql/ — find bookable slots in a Calendar Group

    searchWindowEnd: "2026-06-24T09:00:00-07:00",
