Connect your Cal.com account so visitors can book meetings through your chatbot, and every booking can be captured as a lead in BubblaV. BubblaV connects to Cal.com with secure OAuth — no API keys for you to manage.
Connection is live today. AI booking actions (book, check availability, cancel, reschedule) and automatic booking-to-lead capture are rolling out incrementally. Connect your account now to be ready.

​
Why Connect Cal.com?

  • Book in chat: Visitors book meetings without leaving the conversation
  • Capture leads: Every booking is saved as a lead with attendee details
  • Real-time availability: Show open slots straight from your Cal.com calendar
  • 24/7 scheduling: Take bookings outside business hours
  • Cal.com or Cal.eu: Works with both the global and European instances

​
Prerequisites

  • An active Cal.com account on Cal.com (app.cal.com) or Cal.eu (app.cal.eu)
  • At least one event type set up in Cal.com

​
Connect to Cal.com

1

Navigate to Integrations

Go to Dashboard → select your website → Integrations → find Cal.com
2

Click Connect

Click the Connect button next to Cal.com
3

Authorize on Cal.com

You’ll be redirected to Cal.com. Log in (if needed) and click Allow to grant BubblaV access. BubblaV uses PKCE OAuth, so there’s no client secret to handle.
4

Return to Dashboard

You’ll be redirected back automatically and the integration will show as Connected with your Cal.com account details.

​
Cal.eu accounts

If your Cal.com account is on the European instance (app.cal.eu), your BubblaV admin must point BubblaV at the EU endpoints (CALCOM_OAUTH_AUTHORIZE_URL, CALCOM_OAUTH_TOKEN_URL, CALCOM_API_BASE_URL) before you connect. The OAuth client and your account must be on the same instance.

​
What This Enables

Once connected, BubblaV is authorized to access your Cal.com account with these scopes:
ScopeWhat it allows
BOOKING_READView your bookings (capture as leads, show “my appointments”)
BOOKING_WRITECreate, cancel, and reschedule bookings
EVENT_TYPE_READList your event types (show available meetings to book)
PROFILE_READVerify the connected account
AI booking actions and automatic booking-to-lead capture are rolling out — once enabled, you’ll be able to ask the bot things like “I’d like to schedule a consultation” or “show my upcoming meetings.”

​
Reconnecting

If your connection expires or you need to switch accounts, click Reconnect on the Cal.com integration card. You’ll go through the OAuth flow again to get fresh credentials.

​
Troubleshooting

  • Your Cal.com account and the BubblaV OAuth client must be on the same instance (both app.cal.com or both app.cal.eu).
  • If your account is on Cal.eu, ask your BubblaV admin to configure the EU endpoints, then reconnect.
  • Make sure you clicked Allow (not Deny) on Cal.com’s authorization page.
  • Try disconnecting and reconnecting via the integration card.
  • Ensure you’re logged into the correct Cal.com account.
  • The callback URL registered on your Cal.com OAuth client must exactly match https://www.bubblav.com/api/integrations/calcom/oauth/callback (plus any preview/dev URLs your admin registered).
  • While BubblaV’s Cal.com OAuth client is pending Cal.com admin review, only the client owner can authorize. Other users can connect once it’s approved.
  • Access tokens refresh automatically in the background.
  • If you see a connection error, click Reconnect on the integration card.
