I need an automated reply system connected to my WhatsApp Business number that can handle fully custom user interactions—not just generic FAQs. Incoming messages should trigger tailored flows: think keyword detection, branching questions, data capture, and context-aware follow-ups. I’m open to proven approaches such as the official WhatsApp Business Cloud API, Twilio, or Chat-API, as long as the end result is stable and easy for me to extend. Deliverables • A working bot deployed on my WhatsApp line, ready for real-world traffic • A simple way for me to add or edit triggers and responses (JSON/YAML file, web dashboard, or similar) • Clear setup and hosting instructions so I can maintain the system myself If you’ve built similar WhatsApp automations before, I’d love to see them.
