Cal.com

In one line: Connect Cal.com so your UnleashX agent can check availability, book meetings, reschedule or cancel them, and manage webhooks automatically.

​
1. Overview

Cal.com is an open-source scheduling platform. You publish event types (like “30-minute intro call”), share a booking link, and invitees pick a time that fits your availability — no back-and-forth emails. Once connected, your UnleashX agent can look up your event types, check open slots, create bookings, reschedule or cancel them, and set up webhooks so other systems hear about new bookings. That lets your agent handle scheduling end to end during a call or chat. Connecting Cal.com to UnleashX is useful for sales, support, and customer teams who want to turn “let’s find a time” into a confirmed meeting instantly, without leaving the conversation.

​
2. What you’ll need

  • A Cal.com account (cloud at cal.com or your self-hosted instance).
  • At least one event type set up so there’s something to book.
  • A Cal.com API key.
Any Cal.com user can create an API key for their own account. The key acts as you, so the agent can only manage the bookings and event types your account owns.

​
3. Get your credentials

Cal.com uses an API Key.
1

Open Cal.com settings

2

Go to Developer → API keys

In the sidebar, choose Developer, then API keys. (Direct link: https://app.cal.com/settings/developer/api-keys)
3

Create a key

Click Add / Create new API key, name it UnleashX, optionally set an expiration, and confirm.
4

Copy the key

Copy the generated API key.
The API key is shown only once. Copy it now — if you lose it, delete it and create a new one.
What the key can access
A Cal.com API key reflects your account’s access. UnleashX only calls the endpoints needed for the tools listed in Section 5.

​
9. Frequently asked questions

Is my data stored by UnleashX? UnleashX calls Cal.com live with your key when a tool runs. It doesn’t keep a separate copy of your calendar. Can multiple team members connect? Yes. Each person creates their own API key and connects it to their agent. How do I rotate my key? Create a new key in Cal.com, update it in UnleashX, then delete the old one. Access switches over immediately. Does this work with self-hosted Cal.com? Yes, as long as your instance exposes the Cal.com API and you provide a valid API key.
