WhatsApp receptionist on Cloud API + Claude — paid trial build

I run Buddy AI, a WhatsApp receptionist for appointment businesses in Abu Dhabi (salons, barbers, car detailing, padel clubs). I have a working Node.js receptionist (Express, Anthropic Claude API, WhatsApp Cloud API) and a Meta test number ready to go. PAID TRIAL ($250 fixed): 1. Deploy the existing code on Railway (or Render). 2. Connect the webhook to my Meta test number and verify it. 3. Make a booking end-to-end from a real phone, once in English and once in Arabic. 4. Send me a 2-minute screen recording of it working plus any fixes you had to make. If you've shipped on the Cloud API before, this is 3 to 5 hours. AFTER THE TRIAL: client installs at $800 to $1,300 each (2 to 4 a month, growing), plus small monthly maintenance retainers. Code lives in my GitHub repo. I'm hands-on, I read code, and I give fast answers on WhatsApp. TO APPLY, answer this in two lines at the top of your proposal: what is the difference between a business-initiated template message and a session message on the WhatsApp Cloud API, and why does it matter for appointment reminders? Proposals without that answer are skipped.
