Webhook to check the availability of a time slot in Google Calendar and create the event

Forget about double-booking and endless back-and-forth. Save your time—just send the info and your event gets scheduled only if the slot’s actually free.

Scrambling to manually check for open slots before adding meetings to Google Calendar is a recipe for mistakes, double bookings, and wasted time. Every request means switching tabs, cross-referencing calendars, and sending tedious messages back and forth—often resulting in missed opportunities or frustrated team members when things slip through the cracks. Without automating this, you risk not just precious hours lost to menial coordination, but also your professional credibility when someone realizes you’ve scheduled over an existing event.

This formula from Botize changes everything: a dedicated webhook receives the event details (title, description, desired start/end times), instantly checks your selected Google Calendar for availability within your chosen time slots and timezone, and—if your calendar is clear—books the meeting in seconds. All it takes is a single trigger: no more manual oversight, repetitive admin, or scheduling anxiety. The process is fully customizable too, so you set which calendar is checked, which hours are eligible for booking, and how your timezone is handled. Suddenly, coordination flows smoothly and your attention stays on what matters, not on managing calendars.

Ready to reclaim your time and step into seamless scheduling? Follow the step-by-step instructions to set up this formula in Botize, personalizing it as needed, or use the ready-made template if you want to get started in under a minute. The power to automate your calendar and never double book again is just a few clicks away. Let’s make your schedule work for you—automatically.
