How to build multi-user Google Calendar booking in Webflow Cloud

A detailed tutorial describes how to build and deploy a multi-user Google Calendar booking system as a Next.js app mounted on a Webflow Cloud site. Using a Google service account shared with each teammate’s calendar, the app queries free/busy data across the team, presents 30-minute slots during configured business hours, and assigns each booking to an available teammate through a rotating selection method. It explains required Webflow, Google Cloud, Node.js, Next.js, and environment-variable setup; implements JWT-based Google authentication with Web Crypto; and provides availability and booking API routes that validate requests, recheck availability, and create calendar events. The guide notes important limitations, including possible race-condition double bookings, lack of attendee invitations or visitor confirmations, and the need for bot protection, rate limiting, and database-backed locking before public use. It also covers deployment considerations such as Webflow mount paths, secret handling, client-side base-path configuration, and common failures involving service-account credentials, inaccessible calendars, incorrect API paths, and unsupported Next.js edge-runtime directives.
