How do you automate WhatsApp lead handling?
Use the official WhatsApp Business API (via Meta Cloud API, Twilio, or 360dialog), connect it to your CRM, and route messages through an automation engine with an LLM-based router for intent classification. Always include a human-in-the-loop fallback. Avoid grey-market unofficial APIs, they get banned and take your number with them.
The first decision is the API. Meta Cloud API (free, official, Meta-hosted), Twilio WhatsApp (paid, well-documented, fast onboarding), and 360dialog (German-based, popular in Europe) are the three serious options. All three are official BSPs (Business Solution Providers); all three give you a stable WABA (WhatsApp Business Account) that won't get banned. Skip anything that talks to WhatsApp Web, those numbers get banned routinely.
Architecture is straightforward. Inbound webhooks land in a queue. A small router classifies the message, sales inquiry, support question, spam, follow-up to an existing conversation, usually with an LLM where intent isn't obvious. Sales inquiries get a structured qualification flow; support questions hit a knowledge base or an agent; spam gets dropped. Everything writes to your CRM with an audit log of what was sent and when.
The non-obvious work is the human escape hatch. Customers must be able to reach a human within one or two turns; if they can't, deflection numbers go up while satisfaction craters. Build the handoff in from day one, it's harder to retrofit than to design in.
