I run a custom-built CRM and now want it to communicate natively with WhatsApp Business, giving my team a WATI-style interface without moving away from our existing stack. The goal is a direct, stable link between the CRM and WhatsApp Cloud API (or an equivalent provider such as Twilio) that lets us launch and monitor conversations from inside the CRM itself. Core requirement – full chatbot support. The bot must handle three everyday scenarios end-to-end: • Customer inquiries • Order status updates • Appointment scheduling Inside the CRM I should be able to configure reply flows, store message history against the customer record, and trigger outbound templates when predefined events fire. Webhooks or REST endpoints are already exposed in the CRM, so you can plug straight into those. A lightweight admin panel for template management, opt-in compliance, and basic analytics will round the project off. I expect clean, well-documented code (Node.js), clear setup instructions, and a short hand-off session so my in-house developers can maintain it going forward.

Hi — you want a WATI-style WhatsApp layer inside your existing CRM, not a migration. That's an integration job, and your exposed webhooks/REST endpoints make it clean. My build plan (Node.js): 1. WhatsApp Cloud API link: direct Meta Cloud API integration (Twilio optional fallback) — webhook receiver for inbound messages/status callbacks, sender service with template + session-message handling and rate-limit/retry logic. 2. Chatbot flows for your 3 scenarios: customer inquiries (intent menus + handover to agent), order status (bot pulls status from your CRM REST endpoint by order ID/phone), appointment scheduling (slot offer → confirm → write back to CRM + reminder template). 3. CRM-side conversation view: message history stored against the customer record via your webhooks, agent reply from inside the CRM, event-triggered outbound templates (order shipped, appointment reminder, etc.). 4. Admin panel (lightweight): template CRUD + Meta sync, flow configuration, opt-in/opt-out compliance handling, basic analytics (delivery/read/response rates). 5. Handoff: clean documented code, .env-based setup guide, Meta app/webhook configuration walkthrough, and a live hand-off session with your in-house devs. I run CWC Technologies (4.9★, 87 reviews) — we've shipped WhatsApp Cloud API chatbots and CRM integrations (including AiSensy-style tooling), so template approval quirks and 24-hour session rules are familiar territory. Which CRM stack are the webhooks on (framework/auth)? Saurabh

You need WhatsApp conversations, automation and customer history embedded directly into your existing CRM without replacing its current stack. I would use Node.js with the WhatsApp Cloud API where possible, handling inbound messages through verified webhooks and outbound templates through a queued, retry-safe service. Each conversation will be matched to the correct CRM customer, with message status, timestamps and failures stored consistently. The chatbot engine will support configurable flows for enquiries, order tracking and appointment scheduling, including human handover and event-triggered templates. The admin area will cover templates, opt-in records, flow settings and basic delivery/conversation analytics. Code will be modular, documented and delivered with setup instructions and a developer handover session. Can you share the CRM API documentation, current backend stack, expected monthly message volume and Meta Business/WhatsApp verification status?
