How We Built a WhatsApp Bot in One Night for a Chiropractic Clinic

It was 1 AM on a Tuesday.

We had just spent 8 days visiting HSC Chiropractic with a family member who needed treatment for neck pain. During those visits, we watched Radnyee — the clinic's assistant manager — manually copy and paste the same 8 WhatsApp messages to every new patient, every single day.

The welcome note. The policy message. The intake form. The process explanation. The pricing. The UPI payment instructions. The appointment confirmation. The clinic directions.

Eight messages. Every patient. Every time. Manually.

We went home, pulled up our laptops, and built the bot.

By 3 AM it was working. By morning, it was live.

Here is exactly what the bot does: 1. When a patient sends any first message — instant welcome and clinic policy 2. Asks for patient details (name, age, address, reference) — automatically 3. Explains the treatment process and pricing 4. Shows available appointment slots 5. Sends UPI payment link for ₹500 advance 6. Confirms the appointment with address, Google Maps link, and arrival instructions

The entire flow — from first message to confirmed booking — in under 5 minutes. Without Radnyee typing a single word.

We used Node.js, Express, and the Twilio WhatsApp API. Total build time: 4 hours. Response time improvement: from 14 hours to 3 seconds.

Every clinic, salon, and service business in India is doing this manually right now. They don't have to.
