    What Volty does with Cal.com

    Cal.com runs bookings for clinics and practices that want their own booking pages. Volty connects to Cal.com with one sign-in. It can read your event types, open slots and bookings, so a patient asking on WhatsApp is offered times that are free. When an admin turns it on, Volty books, confirms or cancels the appointment in Cal.com.

    • Only open slots

      Times come from Cal.com's own availability.

    • Booked in the chat

      The patient picks a time and Volty books it.

    • Cancel and rebook

      When those tools are on, Volty keeps Cal.com in step.

    • Changes start Off

      Each write can wait for a colleague to approve.

    A cancellation

    The patient's back is better. Volty finds the booking and cancels it.

    As an automation

    Describe it to Volty in a sentence; it drafts the automation and an admin turns it on.

    The tools Volty gets

    Common questions

    Can Volty change records in Cal.com?

    Only when an admin allows it. Every tool has its own switch: tools that only read can be turned on, and tools that change a record start Off. A tool that is on can be set to check with staff, so each change waits for a colleague to approve it.

    How much does it cost to connect Cal.com with Volty?

    Every Volty plan includes seats, active contacts and AI credits and starts with a free 7-day trial, and the plan prices are on voltade.com/pricing. Meta bills message charges separately for WhatsApp, Instagram and Messenger.
