Everything your agent can do with Calendly and Vapi ## Triggers and actions 5 triggers · 39 actions - Trigger **Canceled scheduled event (polling)** Triggers when a scheduled event is canceled. - Trigger **New scheduled event (polling)** Triggers when a new scheduled event is created. - Action **Cancel scheduled event** Cancels a scheduled event with a specified reason for the cancellation. - Action **Create single-use scheduling link** Creates a single-use booking link that allows one person to schedule an event. - Action **Get current user** Returns the authenticated user's profile including name, email, timezone, and scheduling URL. - Action **Get event type** Returns details for the specified event type. - Action **Get invitee** Returns details about a specific invitee for a scheduled event. - Action **Get invitee next scheduled event** Gets the next scheduled event for the invitee specified by their email. - Action **Get scheduled event** Returns details about a specific scheduled event. - Action **Get user availability schedule** Returns details for the specified user availability schedule. - Action **List event invitees** Returns the list of invitees for a scheduled event, optionally filtered by status. - Action **List event type availability schedules** Returns the event type's availability schedules. - Action **List event types** Returns your calendar's event type templates, optionally filtered by scope and active status. - Action **List organization memberships** Returns all members of the connected Calendly organization (paginated). One record per membership: user_email, user_uri, user_name, role. - Action **List scheduled events** Returns scheduled events, filterable by scope, status, date range, and invitee email. - Action **List user availability schedules** Returns the user's availability schedules. - Action **List webhook subscriptions** Returns all webhook subscriptions for your organization. - Action **Mark invitee as no-show** Records that an invitee did not attend their scheduled event. - Action **Undo invitee no-show** Removes a no-show marking from an invitee. - Action **Update event type availability schedule** Replaces a single host's availability schedule on a Calendly event type with explicit date rules (full overwrite). Built for CalendarConnect: push real Mindbody bookable slots into Calendly so only MBO-bookable times are offered. CRITICAL: the host is targeted by the NESTED availability_rule.user — a top-level user alone is silently ignored and Calendly replaces the OAuth token owner's schedule instead.

Any of Calendly's 2 triggers in the catalog, including New scheduled event (polling) and Canceled scheduled event (polling). Describe the moment in plain language and your agent picks the right one. ### ### What can your agent do in Vapi when something happens in Calendly? Any of Vapi's 21 actions, including Create Call, Create Chat, Update Call and Update phone number. Your agent maps the data both ways and tests every scenario before it ships. ### ### Can it also run from Vapi to Calendly? Yes. When something happens in Vapi, your agent can act in Calendly too. This page covers both directions: Vapi's triggers and Calendly's actions are listed here as well. ### ### Do I have to build a connector for Calendly or Vapi? No. Both are in the catalog with their triggers and actions. You describe the automation; your agent builds it, tests every scenario and keeps it running. ### ### Can my AI client use Calendly and Vapi without building an automation? Yes. With your AI client connected to APIANT, ask it to do something in either app once and it runs that action on the spot. Ask for an automation and your agent builds it, tests every scenario and keeps it running. One connection covers both. ### ### What happens when something fails? Your agent works that out for you. It plans the failure paths along with the happy path, then tests every scenario before it ships. ### ### Is there a free plan? Yes. Every plan includes the agent, including free, and building from your own AI client spends no assistant credits.
