Cal.com

Sim's Cal.com integration adds 19 Cal.com tools and 9 real-time triggers to the AI agents you build in Sim's visual workflow builder — no code required. Manage Cal.com bookings, event types, schedules, and availability. Teams often pair Cal.com with Rippling and Linear in the same agent.

You can list Bookings, create Booking, get Booking, cancel Booking, and reschedule Booking with Cal.com in Sim, plus 14 more Cal.com tools listed on this page. Each runs as a tool inside an AI agent block, so an agent can chain Cal.com with services like Rippling and Linear and apply LLM reasoning between steps.

Connecting Cal.com takes about five minutes: (1) Create a free account at sim.ai. (2) Create an agent in your workspace. (3) Drag a Cal.com block onto the workflow builder. (4) Connect your Cal.com account with one-click OAuth — no credentials to copy. (5) Pick a tool such as "List Bookings", wire up its inputs, and click Run — your agent is live.

Add a Cal.com block to your agent and select "List Bookings" as the tool. List all bookings with optional status filter. Fill in the required fields — inputs can reference outputs from earlier steps, such as text generated by an AI block or data fetched from another integration. No code is required.

Add a Cal.com trigger block to your agent and copy its generated webhook URL into Cal.com's webhook settings. Sim supports 9 real-time triggers for Cal.com: CalCom Booking Created, CalCom Booking Cancelled, CalCom Booking Rescheduled, CalCom Booking Requested, CalCom Booking Rejected, CalCom Booking Paid, and 3 more. Once configured, every matching Cal.com event starts your agent instantly — no polling, no delay.

Sim receives the full event payload Cal.com sends — typically the record or object that changed, plus metadata like the event type and timestamp. For example, the "CalCom Booking Created" trigger fires when a new booking is created in Cal.com. Every field in the payload is available as a variable you can pass to AI blocks, conditions, or other integrations.
