Frequently Asked Questions

How do I connect Cal.com to HubSpot?

There's no native integration. To connect them, you will need a middleware tool like Make or n8n.

Is the connection between Cal.com and HubSpot secure?

Yes. This integration typically uses OAuth 2.0, meaning you grant permission via a secure login window. You do not need to share your raw password, and you can revoke access at any time from your Cal.com security settings.

Is the sync one-way or two-way?

This is typically a one-way sync: Cal.com → HubSpot. Changes in HubSpot do not sync back to Cal.com.

Will existing data in Cal.com sync to HubSpot?

Usually, no. Most native integrations are "forward-looking," meaning they only sync data created or updated *after* you activate the connection. To move historical data, you will likely need to perform a one-time CSV export/import manually.

Can I sync custom fields?

Native integration is limited to standard fields. For custom field mapping, use an automation tool.

Can I add approval steps before syncing?

Native integrations can't do this. For workflows that need human review (e.g., "Manager must approve before creating invoice"), use Make or n8n to pause the workflow on a webhook or Slack approval before it continues.
