How to set up automatic messages on WhatsApp: step by step
Step-by-step instructions for placing an automatic message on WhatsApp Business and WhatsApp Web: welcome, absence, qualification and after-sales, without programming.
This is the configuration step by step. If you want to understand the complete picture of automatic messages (types, strategy, when not to use them), start with complete guide to automatic messaging on WhatsApp. Here the focus is hands-on: the 5 types that matter and how to configure each one without programming. The prize is big: leads responded in the first hour are 7 times more likely to qualify than those who wait longer[1], and the automatic response resets this waiting time.
Automatic message types
1. Welcome
Triggered on the first message from the contact. Don't use it to "sell" — use it to confirm you received it and promise a next step.
"Hi! I received your message. I will respond to you within 15 minutes during business hours (Mon-Fri 9am-6pm). Outside of these hours, I will get back to you the next business day 🙏"
2. Absence (outside of working hours)
Only sends messages outside opening hours. Let me know when you'll be back.
3. Qualification
Bot asks what is necessary before the human enters. Accepts free text or buttons.
4. Confirmation/reminder
Appointment reminder, confirmed purchase, delivery time. sends messages at a scheduled time.
5. After-sales
X days after purchase: ask for review, offer cross-sell, restore relationship.
Official API vs Extension
You can automate via:
- WhatsApp Business app — welcome, away, and basic quick reply messages. Limit: ~3 models.
- Official API (with BSP) — unlimited automation but with cost per conversation and bureaucracy of approved templates.
- Extension for WhatsApp Web (Zapext) — complete automation, no cost per message, 1-click installation. Ideal for 99% of SMEs.
When NOT to use automation
- Premium client in delicate negotiation.
- Serious complaints or crisis — always human.
- Beginning of a relationship in consultative sales (high-ticket B2B).
How to configure everything on Zapext
- Install the free Chrome extension.
- Em Chatbot, configure keyword (e.g. "hi", "hello", "price") and action (text, audio, media, transfer to human).
- Em Scheduling, schedule recurring messages (welcome, absence, after-sales).
- Test with your own number before activating for everyone.

Frequently asked questions
Can automatic message block my number?
Reactive auto-replies (when the customer speaks first) carry low risk. The high risk is bulk messaging without cadence.
Does it work on regular WhatsApp Business?
Limited: the official app only allows welcome, absence and basic quick responses. For full streams, use Zapext.
How do you know if automation is bothering you?
Simple metric: If more than 5% of responses are 'I want to speak to a human' or swearing, simplify automation.
