How to Set Up WhatsApp Auto Reply for Your Business (2026 Guide)
By ReplyMate Team · Published May 26, 2026
Three ways to set up WhatsApp auto reply — from the free built-in option to AI-powered platforms that actually understand customer questions. This guide walks through each method with step-by-step instructions, so you can pick what fits your business.
Three levels of WhatsApp auto reply
| Level | Method | Cost | Intelligence |
|---|---|---|---|
| Basic | WhatsApp Business app | Free | Same message to everyone |
| Intermediate | WhatsApp Business API + rules | RM 200-500/mo | Keyword triggers, decision trees |
| Advanced | AI-powered platform | RM 99-399/mo | Understands natural language, context-aware |
Method 1: Free WhatsApp Business app (basic)
Best for solo businesses that just need an away message when they are not available.
Step-by-step setup
- Download the WhatsApp Business app (not regular WhatsApp) from Google Play or App Store.
- Register with your business phone number and complete your business profile.
- Go to Settings → Business Tools → Away Message.
- Toggle on "Send away message".
- Tap the message to edit it. Example: "Terima kasih kerana menghubungi [Business Name]. Kami akan membalas dalam masa 24 jam. Untuk tempahan segera, sila hubungi 012-XXXXXXX."
- Choose the schedule: Always send, Custom schedule, or Outside business hours.
- Choose recipients: All, selected contacts, or everyone except certain contacts.
- Tap Save.
You can also set up a Greeting Message (Settings → Business Tools → Greeting Message) that sends automatically to first-time customers.
Limitations: Only one away message and one greeting message. Cannot answer specific questions. Only works when you set status to away. No automation for bookings, menu inquiries, or FAQ. One device only — no team access.
Method 2: WhatsApp Business API + keyword rules (intermediate)
Best for businesses with higher volume that need different responses for different types of inquiries.
How it works
- Sign up with a WhatsApp Business API provider (WATI, SleekFlow, Respond.io, ForwardChat).
- Go through Meta's business verification — submit SSM registration, verify phone number. Takes 1-2 weeks.
- Set up keyword triggers in the platform's flow builder: "menu" triggers your menu response, "booking" triggers your booking flow, "price" triggers your price list.
- Create decision trees for multi-step conversations (e.g., booking flow: ask service → ask date → ask time → confirm).
- Test with your own number before going live.
Limitations: Keyword matching breaks when customers use different phrasing. "Ada slot tak?" and "I want to book" and "boleh reserve?" all mean the same thing but need separate keyword rules. Adding every variation is time-consuming and incomplete. Mixed-language messages (Manglish) cause frequent misses.
Method 3: AI-powered auto reply (advanced)
Best for businesses that want intelligent, human-like responses to any customer message.
How it works with ReplyMate
- Create an account at replymate.pro/signup.
- Scan the QR code with your WhatsApp — works with your existing personal or business number.
- Upload your business information: services, pricing, operating hours, FAQ, location, policies.
- Choose your AI mode: full auto-reply (AI responds instantly) or approve-before-send (AI drafts, you tap to send).
- The AI starts handling messages immediately. It understands BM, English, Mandarin, and Manglish without any keyword configuration.
What AI auto reply can do that basic auto reply cannot
- Understand intent: "eh boss esok ada slot tak" → the AI knows this is a booking inquiry and responds with availability.
- Handle follow-ups: Customer asks about pricing, then immediately asks "can I book tomorrow?" — the AI continues the conversation naturally.
- Answer from your knowledge base: Upload your menu, FAQ, or service list and the AI uses it to answer specific questions accurately.
- Switch languages per message: Customer starts in English, switches to BM mid-conversation — the AI follows seamlessly.
- Work 24/7: No manual "away" toggle needed. The AI responds whether you are online, asleep, or serving customers.
Which method should you choose?
| Your situation | Recommended method |
|---|---|
| Solo business, under 10 messages/day | Free WhatsApp Business app |
| E-commerce with structured order flows | API + keyword rules |
| Service business (clinic, salon, restaurant, tuition centre) | AI-powered (ReplyMate) |
| Multiple branches, multilingual customers | AI-powered (ReplyMate) |
| Want full control over every response | AI with approve-before-send |
The bottom line
The free WhatsApp Business away message is fine for sole proprietors who just need to say "I will reply later." But for any business that receives more than 20 WhatsApp messages a day, upgrading to AI-powered auto reply pays for itself within the first week — through recovered inquiries, faster bookings, and zero missed after-hours customers.
Frequently asked questions
Can I set up auto reply on WhatsApp for free?
Yes. The free WhatsApp Business app lets you set up basic away messages and greeting messages. Go to Settings > Business Tools > Away Message to enable it. However, these are static messages — they cannot answer specific questions, handle bookings, or respond differently based on what the customer asked.
What is the difference between WhatsApp auto reply and a WhatsApp chatbot?
Auto reply sends the same pre-written message to everyone. A chatbot (especially AI-powered ones) understands what the customer is asking and generates a relevant response. Auto reply says "We will get back to you soon." A chatbot says "Yes, we have slots available tomorrow at 2pm and 4pm. Which works for you?"
Do I need coding skills to set up WhatsApp auto reply?
No. The WhatsApp Business app auto reply needs zero technical skills. AI platforms like ReplyMate also require no coding — just scan a QR code, upload your business info, and the AI handles the rest. Only custom API integrations require developer involvement.
Can auto reply work when I am online?
The WhatsApp Business app only sends away messages when you manually set your status to "away." AI platforms like ReplyMate work 24/7 regardless of your online status — they reply to every message, whether you are available or not.
