WhatsApp Appointment Scheduling with Google Calendar

This workflow enables service-based businesses and freelancers to handle appointment scheduling directly through WhatsApp conversations. It starts with a trigger on WhatsApp messages, sends a reservation link, collects the user's name and preferred date, verifies availability in Google Calendar, presents only free time slots for selection, creates the event automatically upon confirmation, and logs all details in a Postgres database for record-keeping.

Key benefits include eliminating manual coordination errors, preventing double-bookings with real-time availability checks, and providing full control without external scheduling platforms. It saves significant time for small teams by streamlining the entire process from inquiry to confirmed booking.

Use cases: Freelance consultants booking client calls, salons or clinics managing appointments, tutors scheduling sessions, or any service provider using WhatsApp for customer communication. Setup requires Postgres table creation via SQL script and credentials for WhatsApp Business API, Google Calendar, and Postgres.
