I’m looking to launch a WhatsApp-based chatbot that can answer medical and fitness questions around the clock. Each user may ask up to ten questions per day free of charge; from the eleventh question onward the bot must prompt for payment before continuing. Core functions • Collect and store each user’s medical history and fitness goals, keeping the data encrypted and compliant with WhatsApp Business policy. • Provide a simple admin dashboard where I can browse conversations in real time and export all collected data to an Excel file with one click. • Connect a payment gateway so users can seamlessly upgrade when they exceed the daily free quota—Stripe, PayPal, or another mainstream option is fine as long as it supports subscriptions or pay-per-use. Premium tier deliverables • Personalized fitness plans generated automatically from the user’s stored data • Direct access to expert advice via flagged messages that route to a human specialist when needed • Priority responses that move paid users to the front of the queue Acceptance will be based on: 1. Smooth, uninterrupted WhatsApp UX from first greeting through payment confirmation. 2. Accurate query counting and automatic reset every 24 hours. 3. Clean Excel export matching the database schema for all collected fields. 4. Secure handling of medical history and fitness goals with clear audit logs. If you’ve built WhatsApp bots with data export and payment integration before, I’d love to see your approach and timelines.
