Hey Product Hunt! 👋 I'm the solo builder behind WA Messaging Bot — a REST API for sending WhatsApp messages without going through Meta's official approval process. Why I built this: I kept running into the same wall every time I wanted to add WhatsApp notifications to a project — business verification, Facebook Business Manager, weeks of waiting, and per-conversation fees. So I built my own alternative and put it on RapidAPI. What it does: Send text, images, files, OTPs to any WhatsApp number via REST Manage groups, channels, and multiple sessions Webhooks with HMAC SHA-512 verification for incoming messages QR code or pairing code auth (one-time setup, then it persists) Works with Python, Node.js, PHP, Go — any language that can make an HTTP request Where it's at: Honest numbers — 8 developers have tried it, 2 gave great feedback, still working toward my first paying customer. Launching here to get real feedback from builders who'd actually use it. Free plan: 100 messages/month, no credit card required. Would love feedback on: Is the onboarding clear enough? What use cases are you missing? What would make you upgrade to a paid plan? Thanks for checking it out 🙏 https://rapidapi.com/jevil257/ap...
