Cal.com recently deprecated their API v1, which completely broke the native n8n Cal.com node and trigger (giving the error: “API v1 has been decommissioned. Please migrate to API v2”).
I’ve opened a feature request to get the node updated to API v2 so we can stop relying on manual HTTP/Webhook workarounds.
If your booking workflows are currently broken, please drop a
