Complete guide to building a no-code WhatsApp chatbot: types, flows, integrations, and metrics. Updated 2026.

By Daniel Machado

A well-designed chatbot answers 40-60% of messages automatically, at quality — and gives your team back time for what matters. Here's the full landscape for building yours in 2026.

Types of WhatsApp chatbots

  1. Keyword (rules): responds when the customer types "X". Most common.
  2. Button (guided flow): offers options; customer clicks. Highest completion rate.
  3. AI (LLM): understands natural language. Newer, costlier, requires supervision.

Frequently asked questions

Keyword chatbot or AI chatbot?

For SMBs in 2026, start with keywords. Covers 80% of cases with 20% of the effort. AI fits when volume justifies it.

Can I run a chatbot only outside business hours?

Yes. Set up the flow with an 'after-hours' trigger and it only fires in that window.

Does the chatbot work on mobile?

Zapext runs on WhatsApp Web (computer). Your customer chats from their phone as usual.
