How to Set Up WhatsApp Business Auto Reply (Step-by-Step)

Setting up auto reply takes five minutes. Making it actually useful takes this guide.

WhatsApp Business auto reply is one of those features that every business owner knows exists but few configure properly. Most stop at the default "Thanks for your message, we'll get back to you soon" and call it done.

That generic response costs you customers. A Salesforce report found that 80% of customers say the experience a company provides is as important as its products. Your auto reply IS the experience when your team is unavailable.

This guide walks you through every step for both the free WhatsApp Business app and the WhatsApp Business API, with clear explanations of what each method can and cannot do.

What Is WhatsApp Business Auto Reply and How Does It Work?

WhatsApp Business auto reply is a built-in feature that automatically sends a pre-written message when customers contact your business outside set hours or for the first time. Meta reports that over 50 million businesses worldwide use the WhatsApp Business app, with auto reply being the second most-used feature after catalogues.

Auto reply in WhatsApp Business comes in two forms:

1. Greeting Message — Sent when someone messages your business for the first time or after 14 days of no conversation.
2. Away Message — Sent when someone messages outside your configured business hours or when you manually toggle "away" mode.

Both run entirely within WhatsApp's servers. You do not need to keep the app open or your phone connected to the internet for them to work — though the free app does require your phone to have recently synced.

The API version adds a third layer: automated flows that respond based on keywords, customer segments, or conversation context.

How Do You Set Up Auto Reply on the WhatsApp Business App?

The WhatsApp Business app is free and available on Android and iOS. Setup takes under three minutes, but the limitations are significant — you get exactly one greeting and one away message with no conditional logic. According to Meta's own documentation, these basic features suit solo operators with predictable business hours.

Step 1: Open Business Tools

Open your WhatsApp Business app. Tap the three dots (Android) or Settings (iOS) in the top right. Select Business Tools.

Step 2: Set Up Greeting Message

Tap Greeting Message. Toggle on Send greeting message.

Write your greeting. This message fires when:

• A customer messages you for the very first time.
• A customer messages after 14 days of inactivity.

Choose your recipients:

• Everyone — All incoming messages.
• Everyone not in address book — Only new contacts.
• Everyone except — Exclude specific contacts.
• Only send to — Specific contacts only.

Step 3: Set Up Away Message

Go back to Business Tools. Tap Away Message. Toggle on Send away message.

Write your away message. Configure the schedule:

• Always send — Active 24/7. Use this if you want auto replies running constantly.
• Custom schedule — Set specific times. Useful for lunch breaks or half days.
• Outside business hours — Automatic based on your business hours setting.

Step 4: Configure Business Hours

If you chose "Outside business hours," ensure your hours are set correctly.

Go to Business Profile → Business Hours. Set your hours for each day of the week.

Away messages will fire for any message received outside these hours.

Step 5: Set Up Quick Replies

Quick replies are not auto replies — they are shortcuts you send manually. But they complement your auto reply setup.

Go to Business Tools → Quick Replies. Tap the + button.

Create shortcuts for common responses:

• /thanks → Thank you message
• /hours → Business hours
• /location → Address and directions
• /price → Pricing information

When chatting, type / followed by the shortcut name to insert the pre-saved message.

What Are the Limitations of the Free WhatsApp Business App?

The free WhatsApp Business app serves as a starting point, but its auto reply features have hard limitations that become bottlenecks once a business handles more than 20-30 messages per day. A survey by Gartner found that 58% of businesses outgrow basic messaging tools within their first year of adoption.

Here are the specific limitations:

For a solo operator like a freelance tutor or home-based baker, these limitations are manageable.

For a salon with three staff, a clinic with two doctors, or a tuition centre with multiple subjects, they become a daily frustration.

How Do You Set Up Auto Reply Using the WhatsApp Business API?

The WhatsApp Business API unlocks unlimited auto reply templates, conditional logic, multimedia messages, and AI integration. Businesses using the API see a 3x improvement in customer response satisfaction compared to the free app, according to Meta's business case studies.

The API is not a standalone app. You access it through a Business Solution Provider (BSP) like AlwaysON, WATI, or Respond.io.

Here is the general setup process:

Step 1: Choose a BSP and Connect Your Number

Select a WhatsApp Business API provider. Sign up and connect your business phone number.

With AlwaysON, this process takes about 10 minutes:

1. Create your account at alwayson.my.
2. Enter your business details.
3. Verify your phone number via SMS or voice call.
4. Complete Facebook Business verification (required by Meta).

Step 2: Create Message Templates

In your BSP dashboard, create templates for different scenarios.

API templates require Meta approval before use. Approval typically takes 1-24 hours.

Template categories:

• Marketing — Promotions, offers, campaigns.
• Utility — Appointment reminders, order updates, confirmations.
• Authentication — OTPs and verification codes.

Auto reply messages fall under Utility and have the highest approval rate.

Step 3: Configure Automation Rules

Set up trigger conditions for each template:

• Time-based: Send Template A during business hours, Template B after hours.
• Keyword-based: Customer says "price" → send pricing template. Customer says "book" → send booking flow.
• First-message: New customer → send welcome template with menu.
• Inactivity: No reply after 24 hours → send follow-up template.

Step 4: Connect Integrations

The API's real power emerges when connected to other tools:

• Calendar/Booking system: Auto-check availability and offer real-time slots.
• Payment gateway: Accept payments directly in chat.
• CRM: Log conversations and customer data automatically.
• AI engine: Generate contextual responses instead of static templates.

Step 5: Test and Launch

Send test messages from a personal number to verify:

• Greeting fires correctly for new conversations.
• Away messages trigger outside business hours.
• Keyword triggers route to correct templates.
• Booking and payment flows complete end to end.

How Do You Write Auto Reply Messages That Actually Convert?

The difference between an auto reply that loses customers and one that converts them comes down to structure. According to a Drift benchmark report, auto replies that include a specific next action generate 42% more customer responses than those ending with passive statements like "we'll get back to you."

Follow this framework:

The ACE Framework

A — Acknowledge: Show you received the message. C — Context: Give useful information. E — Enable: Provide a clear next step.

Bad example:

Thank you for your message. We will get back to you as soon as possible.

This only does A. No context. No next step.

Good example:

Hi! Thanks for messaging GlowSkin Clinic.

We're currently closed (open Mon-Sat, 9AM-6PM).

You can book your appointment anytime here: [booking link]
Or leave your question and we'll reply first thing tomorrow!

This does all three: acknowledges, provides hours context, and enables booking.

Formatting Rules

1. First line: Greeting. Keep it warm but brief.
2. Middle section: Information the customer likely needs.
3. Last line: One clear call to action.
4. Line breaks: Between every section. Never send a text wall.
5. Length: 50-100 words maximum.
6. Emojis: 2-3 maximum. They aid scannability, but too many look unprofessional.

What Mistakes Should You Avoid When Setting Up Auto Reply?

A poorly configured auto reply is worse than no auto reply at all, because it sets incorrect expectations. Support teams report spending 20% more time handling complaints that stem from misleading automated messages, according to Freshdesk's customer service benchmarks.

Mistake 1: Promising a Response Time You Cannot Meet

If your away message says "We'll reply within 30 minutes" but your team takes four hours, you have actively damaged trust.

Fix: Either guarantee a time you can consistently meet, or use ranges like "within a few hours" rather than exact timeframes.

Mistake 2: Forgetting to Update Holiday Messages

Nothing says "nobody is managing this account" like a Hari Raya message still active two weeks after the holiday.

Fix: Set calendar reminders to update holiday auto replies on the first day back.

Mistake 3: Using the Same Message for Everything

Your greeting and away message should be different. A first-time customer needs a welcome. An after-hours message needs business hours.

Fix: Use the API for multiple conditional templates, or at minimum, update your single message based on context.

Mistake 4: No CTA

Every auto reply must tell the customer what to do next. "Thanks for your message" is a dead end.

Fix: Always end with a link, a question, or a clear instruction.

Mistake 5: Ignoring Bahasa Melayu

If your customers message in BM, your auto reply should accommodate that. A purely English auto reply in a mixed-language market like Malaysia creates friction.

Fix: Use bilingual templates or, with AI platforms like AlwaysON, respond in whatever language the customer uses.

How Do You Move from Basic Auto Reply to AI-Powered Conversations?

AI-powered WhatsApp responses handle 80% of routine customer queries without human intervention, according to McKinsey's 2024 AI in customer service report. The transition from static auto replies to AI is not a leap — it is a progression through three stages.

Stage 1: Static Auto Reply (Free)

You are here if you use the WhatsApp Business app's built-in greeting and away messages.

What it handles: Basic acknowledgement. Business hours notification. Generic welcome. What it misses: Specific questions. Booking requests. Pricing enquiries. Follow-ups.

Stage 2: Template-Based Automation (RM50-150/mo)

You reach this stage with a basic API provider or tools like WATI or WASender.

What it handles: Keyword-triggered responses. Multiple templates. Basic routing. What it misses: Complex questions. Multi-step conversations. Context awareness.

Stage 3: AI-Powered Conversations (From RM149/mo)

This is where platforms like AlwaysON operate.

What it handles: Natural language understanding. Real-time booking. Payment processing. Multi-step conversations. Context from previous chats. Bilingual responses.

Frequently Asked Questions

Can I use WhatsApp auto reply for a personal number?

No. Auto reply is only available on WhatsApp Business (free app) and WhatsApp Business API. Personal WhatsApp does not support automated responses. You can download WhatsApp Business for free and transfer your number.

Does the auto reply work when my phone is off?

On the free WhatsApp Business app, your phone needs to have recently synced with WhatsApp servers. If your phone has been offline for an extended period, auto replies may not send. On the API, auto replies work independently of your phone since they run on cloud servers.

Can I set different auto replies for different contacts?

On the free app, you can choose to send your auto reply to "everyone," "everyone not in address book," specific contacts, or exclude specific contacts. However, you cannot create different message content per group — only one message applies. The API allows unlimited conditional templates.

How often does the greeting message send to the same person?

The greeting message sends once per new conversation. After the initial greeting, it will not resend until 14 days of inactivity have passed. This prevents repeat customers from receiving the same welcome message every time they chat.

Is there a limit to how many auto replies I can send per day?

The free app has no daily limit since it only sends one type of greeting and one away message. On the API, Meta sets daily messaging limits based on your account quality tier, starting at 1,000 unique contacts per day and scaling up to unlimited for high-quality accounts.
