Whether you're powering scheduling, automation, or AI assistants, our new [Calendar API](/calendar) gives you structured access to the entire meeting lifecycle — from availability to transcripts — all in one unified model. ## One API. Four core capabilities. - **Free/busy availability** Check when users or teams are available — across platforms. - **Event lifecycle** Read, create, and update calendar events, including support for video conferencing metadata. - **Scheduling links** Access and manage booking links from tools like [Calendly](https://unified.to/integrations/calendly), [SavvyCal](https://unified.to/integrations/savvycal), and more. - **Recordings & transcripts** Retrieve structured recordings, attendee metadata, and transcripts — ideal for AI-powered meeting summaries and training. Everything is returned in a normalized schema with real-time sync — no extra tooling, no provider-specific complexity. [Read the docs ](https://docs.unified.to/calendar/overview) ## Use cases - **AI scheduling assistants** Let your product manage calendars and meetings through a single API. - **Workflow automation** Trigger events based on user availability, meeting status, or link activity. - **In-app scheduling** Embed scheduling flows in your product — no need for third-party tools. - **Post-meeting intelligence** Feed transcripts and metadata into AI models or analytics pipelines. ## Built for scale and security - **Real-time sync** via native or [virtual webhooks](https://unified.to/blog/unlock_real_time_data_with_virtual_webhooks) - **Unified [OAuth](/embeddedauth) & schemas** across every platform - **Zero data storage** — your customers' calendar data never touches our servers ([learn more](https://unified.to/security)) We abstract away auth, webhook orchestration, and third-party platform quirks so your team can focus on building. ## Available now Our Unified Calendar API is available in all plans and accessible during your [30-day free trial](https://app.unified.to/login).
