Patients and healthcare providers deserve effortless telehealth access without wrestling with complex app installs or expired invitation links. Medizys has launched an upgraded WhatsApp video consultation experience featuring single-tap interactive Call-To-Action (CTA) buttons, live real-time delivery and read receipts directly on the patient booking screen, and automated T-15 minute pre-call reminders.

1. Single-Tap Interactive CTA Video Links

Traditional consultation links sent over SMS often get buried or flagged as spam. With Medizys's approved WhatsApp interactive templates and dynamic CTA action buttons, patients receive an official verified WhatsApp message containing a prominent "Join Video Call" button. Tapping it instantly opens their private, encrypted telehealth consultation lobby.

2. Real-Time Delivery & Read Receipts On-Screen

Wondering if the patient received their consultation link is a thing of the past. The Medizys booking confirmation screen now listens to live Meta webhooks over durable edge WebSockets. As soon as WhatsApp delivers the message or the patient reads it, the status badge transforms seamlessly from "Dispatched ✓" to "Delivered to WhatsApp ✓✓" and "Read on WhatsApp ✓✓".

3. Automated T-15 Minute Pre-Call Reminders

To eliminate no-shows and prepare patients for consultations, Medizys runs a serverless scheduled task scanning for consultations starting in 15 minutes. It automatically dispatches an alert with direct room entry links, Web Push notifications, and automated SMS failover so no patient ever misses their doctor.
