--- title: Calendly canonical: https://telnyx.com/integrations/calendly --- # Calendly [Back to Integrations](https://telnyx.com/integrations) # Calendly ### Overview Connect your voice agent with Calendly to schedule meetings and manage availability during phone conversations. The integration allows your agent to check calendar availability, create new bookings, and confirm appointments in real time, ensuring meetings are scheduled directly from live interactions. ### How it works This video shows how a Voice AI agent built on Telnyx voice schedules meetings through Calendly during a phone conversation. The agent checks available time slots, creates a booking based on the caller’s preference, and confirms the meeting directly in the Calendly interface. ### Capabilities The Calendly integration supports the following operations across core objects: Events create\_event get\_event list\_event Invitees get\_invitee list\_invitee Users get\_user [Start building](https://telnyx.com/sign-up) CATEGORY Developer resources DEVELOPER LINKS [Telnyx Voice API fundamentals](https://developers.telnyx.com/docs/voice/programmable-voice/voice-api-fundamentals)[Calendly API reference](https://developer.calendly.com/api-docs/4b402d5ab3edd-calendly-developer) ### About Calendly Calendly is an automated scheduling platform that eliminates the back-and-forth of finding meeting times, letting people book, prepare for, and follow up on meetings effortlessly - from scheduling to recap. ### What moves between the agent and Calendly A Telnyx voice AI agent connected to Calendly can check available time slots and book appointments directly during a phone call, confirming the date and time with the caller in natural language. When someone calls to schedule a consultation, the agent finds open slots that match both parties' calendars and secures the booking on the spot. The agent can retrieve upcoming event details to remind callers of scheduled meetings, and it can cancel or reschedule appointments when plans change - all through conversation. "I need to move my Tuesday appointment to Thursday" triggers a search for available Thursday slots and an automatic update. The agent can also create new event types and manage availability windows based on caller requests, giving administrators a hands-free way to configure scheduling rules without logging into the Calendly dashboard. COMPOSITION ## Pick the job. The primitives light up. Four Calendly assistants. Pick one and the blocks it runs on light up, and the create call attaches Calendly in the same request, the meter prices it. Or click any single block: every primitive sells alone. Loading... One request. Tools attached. You pay the minute, not the connector.
