I need a small automation that listens to every incoming WhatsApp message on my business number, then fires back a predefined reply after a short, human-looking delay. The goal is simple: keep every chat warm so I never miss a sale or support request while I focus on other tasks. Here is what matters to me: • Platform: strictly WhatsApp (no web chat, email, or other channels). • Reply style: “Balasan Cepat” but with a configurable pause—just long enough to feel natural, not robotic. • Flexibility: I want to edit the text templates myself and toggle the delay time without touching code. Ideal delivery: 1. A working auto-reply script, bot, or third-party integration already wired to my WhatsApp Business account. 2. Clear, step-by-step instructions so I can swap messages or adjust the delay on my own. 3. A brief test session to prove messages are received and the timing feels right. If you have experience with WhatsApp Business API, Twilio, WATI, or similar tooling and can turn this around quickly, we’ll be a perfect fit.
