Online appointment booking with Google Calendar (Calendly-style)
A public form for your customers to book an appointment: it checks your Google Calendar, creates the event, confirms by email and, if the slot is taken, suggests the free slots of that day.
Everything is created inactive in a new folder of your account. Nothing runs until you activate it, and you can undo it for 24 hours.
What it does
Your own booking page without paying a subscription. The customer opens the booking form, picks a day and time and fills in their details. The workflow checks that the day and time are valid (working days, minimum notice), looks at your Google Calendar and:
- If the slot is free: it creates the event in your calendar (with the customer as a guest), saves the booking in the
citasData Store with a booking code, sends a confirmation email to the customer and an alert to the professional. - If it is taken: it says so on screen and by email, and suggests the slots that are still free that same day.
What is included: 1 form, 1 workflow and the citas data group (also used by the reminders, cancel/reschedule and approval templates).
What you need: a connected Google account (Calendar) and an SMTP account for the emails.
Limitations: the form does not show a visual picker of free slots: the customer chooses the time from a list and, if it is taken, is told so and offered alternatives. A different Google Meet link is not generated per appointment either: use a fixed video-call link (your own Meet/Zoom) or an address in the LUGAR field. All-day events block the whole day.
