I need a developer who can take our existing customer-support chatbot and wire it into WhatsApp Business first, then lay the groundwork for quick roll-outs to Facebook Messenger, Instagram and our web widget. The bot already handles common enquiries in our internal testing environment; what’s missing is a robust, production-grade integration that delivers the same fast, reliable replies to customers on their preferred channel. Scope • Connect to the official WhatsApp Business (Cloud) API, authenticate with our account and deploy the bot so customers can initiate chats exactly as they do with a human agent. • Preserve the current FAQ logic and conversational context, returning rich-media replies where allowed by WhatsApp. • Build your solution so plugging in additional endpoints (Messenger, Instagram, web) later requires minimal re-work—shared codebase, modular adapters, clear configuration files. • Provide concise documentation and a short hand-off session so my in-house team can monitor, update intents and roll out future channels confidently. .also integration with our platform Acceptance The job is complete when a test customer can message our verified WhatsApp number, receive instant answers to the standard questions we supply, and we see conversation logs in our existing analytics dashboard with no errors or dropped sessions. Please attach a detailed project proposal outlining your preferred tech stack, timeline, key milestones and any past WhatsApp or multichannel bot integrations you have shipped.
