WhatsFlow-Pro
A complete WhatsApp Business automation platform with multi-agent inbox, bulk messaging, campaign analytics, customer CRM and Meta Cloud API integration.
Key Features & Architecture Modules
Client & Project Overview
WhatsFlow-Pro is an enterprise conversational marketing and customer support platform built for e-commerce brands, healthcare providers, and financial institutions requiring compliant, high-scale WhatsApp communications.
The Engineering Challenge
The client required an enterprise-grade platform capable of handling millions of customer interactions without triggering Meta spam rate-limits, while providing a frictionless no-code flow builder for non-technical marketing managers.
The ARSAJIX Solution
ARSAJIX architected an asynchronous webhook processing engine using Node.js and Redis bull-queues connected directly to the official Meta WhatsApp Business Cloud API. We integrated a visual drag-and-drop decision tree builder in React and built a multi-agent live chat CRM with real-time WebSocket state synchronization.
System Architecture & Implementation Highlights
- Asynchronous webhook ingestion absorbing 2,500 requests per second
- Redis BullMQ prioritization guaranteeing urgent transactional OTP dispatches
- Official Meta Cloud API direct integration eliminating third-party middleware markups
- Interactive WhatsApp buttons, list pickers, and automated media catalog dispatches
