I gave a dental clinic a receptionist that never sleeps. 🦷
Today I finished building a WhatsApp AI Receptionist — and tested it live, end to end.
A patient messages the clinic on WhatsApp. Within seconds they get a polite, human-sounding reply with the clinic's REAL fees, timings and doctors — because the AI answers only from the clinic's own database. It never invents a price. If it doesn't know, it says it will confirm with the owner.
The honest part? Halfway through testing, it broke. Spectacularly. 😅 WhatsApp sends invisible "delivered" signals — and my system was answering those signals too. 192 executions later, I found the cause hiding in one execution log: no message, just a delivery status. One guard node later, the loop was dead and the replies were clean.
That debugging session taught me more than any tutorial: → Always guard your trigger. Not every webhook event is a message. → Read the raw execution JSON before guessing. The answer is always in there.
Now I'm setting this up for clinics and local businesses that live on WhatsApp — instant replies, appointments captured, every lead saved, even at 2 AM.
If your business answers the same 10 questions on WhatsApp every day — what would you automate first?
