Automating WhatsApp isn't optional anymore for any business getting more than 20 messages a day. Customers expect instant replies — even at 11pm — and no human can keep that pace without burning out.
Step 1 — Choose WhatsApp Business App or Cloud API
WhatsApp Business App (the phone one) works for 1 user and simple messages. For serious automation you need the Cloud API: official from Meta, no ban risk, multi-agent, and integrates with platforms like what-o. The Cloud API is free to set up; you only pay for outbound business-initiated conversations.
Step 2 — Connect your number to an AI platform
Several platforms orchestrate the Cloud API + AI. what-o does it in 2 minutes via Meta Embedded Signup: one click, you authorize your number, done. No code, no certificates, no manual webhook setup.
Step 3 — Upload your knowledge
The agent is only as good as what it knows. Drop your catalog (PDF, CSV or Google Sheets), your hours, your FAQs. The AI builds a semantic index and only answers with that info — zero hallucinations, zero promises you can't keep.
Step 4 — Define when to escalate to a human
Don't automate everything. Set clear rules to hand off to your team when: the customer asks for a person, there's a complaint, or the AI doesn't know the answer. what-o detects intent and notifies you via web/email/internal WhatsApp.
Common mistakes to avoid
Three typical mistakes: (1) using unofficial APIs or shady BSPs — high ban risk; (2) letting the bot answer everything, even what it doesn't know — damages the brand; (3) not monitoring the first week — the AI improves a lot with your feedback.
