91+M WhatsApp Order Update Integration

I need my existing website connected to the 91+M platform so it can automatically send WhatsApp messages whenever an order or booking status changes. The site already tracks each order’s state; what’s missing is the API handshake that pushes a templated “order received, shipped, delivered, etc.” notification to the customer’s WhatsApp number in real-time. Here’s what I’m expecting: • A clean, documented connection between my site and the 91+M API (REST or webhook—whatever is best). • Message templates set up and approved on 91+M for the common order events. • A simple config file or admin panel option where I can edit credentials and turn messages on or off without touching code. • End-to-end test proof: place a sample order, watch the WhatsApp update arrive, and share the log or screen recording. Tech stack on my side is standard LAMP, but I’m open to a small Node or Python micro-service if that makes life easier. Just keep the final deployment lightweight and ready to drop onto my current server. Once it’s running smoothly, hand over concise setup instructions so I can maintain it myself.
