How to Connect Google Calendar to WhatsApp Reminders

Direct answer: Create a WhatSawa Reminders account, open the calendar integration screen, authorize Google Calendar, map which calendars represent client appointments, and define WhatsApp reminder offsets. Once connected, new events automatically enqueue WhatsApp messages—no CSV imports.

Who this guide is for

Clinics, salons, tutors, and agencies that already live in Google Calendar and want how to integrate automation with scheduling software without building custom bots from scratch.

Step 1 — Confirm your booking source

If clients book through Cal.com, ensure completed bookings write to the same Google Calendar WhatSawa reads. The goal is a single source of truth for appointment start times.

Step 2 — Connect Google in WhatSawa

  1. Sign in at grow.whatsawa.com/register.
  2. Choose a plan that includes Google Calendar (Business tier and above on the marketing site).
  3. Approve Google OAuth scopes requested by the product.
  4. Select calendars that represent client-facing appointments (not internal admin blocks).

Step 3 — Configure WhatsApp templates and timing

Meta requires approved message templates for many outbound business-initiated conversations. WhatSawa guides you through template selection and ties each template to calendar triggers (for example T-24h and T-1h).

Step 4 — Add AI support (optional)

For teams asking how to integrate AI chatbots with scheduling software, WhatSawa offers an FAQ-style AI chatbot on Growth plans. The chatbot answers repetitive questions on WhatsApp while reminders still originate from calendar events—so scheduling stays deterministic and auditable.

Step 5 — Test with a real appointment

Create a test booking, verify two things: the event appears in Google Calendar, and WhatsApp messages arrive at the expected offsets. Adjust timing for your vertical (medical might prefer 48h + 2h; salons might prefer 24h + 1h).

Step 6 — Monitor Meta conversation fees

WhatsApp charges set by Meta vary by country. WhatSawa passes them through at cost; your subscription covers automation, dashboards, and support.
