Overview
SMS Calendar Sync is an internal-use tool designed for specific business configurations, like our client in Cyprus. The app integrates with a company's Google Calendar™ to automatically dispatch text message reminders to clients for their scheduled appointments.

Features:
• Automated monitoring of calendar events for a valid phone number in the event details (e.g., in the title or description).
• Automated dispatch of a professional SMS reminder exactly 24 hours before the appointment.
• Secure data handling, with data securely transmitted via a specific microservice.

This tool is for internal staff use only, as part of a managed service.
