Case: WhatsApp Business Automation Turnkey Solution

Scaling Customer Communications via WhatsApp Business API

I am a developer. In this case study, I demonstrate how I transform WhatsApp from a regular messenger into a powerful tool for sales and customer support: automating conversations, integrating with CRM, and removing Facebook's limits for mass messaging.

Practical case: automation for a network of dental clinics

• Initial data: 12 branches, 200+ patients per day, administrators are overloaded with calls and appointment scheduling, 40% of patients do not arrive at their scheduled time (no-show).
• Roles and Permissions: clinic administrators, doctors, managers, system integrator. Delineation of access rights to patient data.
• System functions: Appointment booking via WhatsApp chatbot, automatic 24-hour reminders, integration with medical CRM, preventive check-up notifications, online payment for appointments.
• Technical implementation: WhatsApp Business API, AI chatbot based on OpenAI API, message queue, CRM integration via REST API, webhook for real-time notifications.
• Results: Reduction of administrator workload by 65%, no-shows decreased by 40%, repeat visits increased by 28%. System ROI within 4 months.

Quick immersion into context

• Conversations with responsible persons: automation goals, current pain points, KPIs and success metrics.
• Domain description: customer journey, customer touchpoints with the brand, dialogue scenarios.
• Integrations Map: CRM, payment systems, analytics, internal databases; availability requirements.

Architectural solutions and technologies
