Method 1: Auto Reply with WhatsClaw (Step by Step)

Download and Install WhatsClaw

Get WhatsClaw from the Google Play Store or visit whatsclaw.in. The app works on any Android 7+ phone. Install it like any other app.

Tip: WhatsClaw is free to start. You can set up auto-reply and test it before opting into any paid plan.

Grant Accessibility Permission

Open WhatsClaw and enable the Accessibility service. This is how the app reads incoming messages and sends replies automatically — the same way screen readers work.

Go to Settings → Accessibility → WhatsClaw
Toggle it ON
Confirm the permission dialog

Important: WhatsApp requires all auto-reply apps to use Accessibility. This permission stays on your device — WhatsClaw doesn't send your messages anywhere.

Create Your First Auto-Reply Rule

In the WhatsClaw app, tap "Add Rule" to create a keyword-based auto reply:

Keyword: Type the word or phrase that triggers the reply (e.g., "price", "hi", "interested")
Reply Message: Write the auto-reply text (e.g., "Hi! Thanks for reaching out. Here's our current pricing: ...")
Match Type: Choose Exact Match, Contains, or Starts With

Pro Tip: Create rules for your most common queries: "price", "timing", "location", "delivery", "stock". Cover the top 10 questions you get daily.

Set Up Away Message (Business Hours)

Don to reply 24/7? Set business hours so auto-reply only triggers when you're "away":

Go to "Away Message" in the app
Set your business hours (e.g., 10 AM - 8 PM)
Write your away message: "Hi! We're currently closed. We'll reply when we reopen at 10 AM. For urgent matters, call: [phone]"
Toggle "Enable Away Message" ON

Outside business hours, anyone messaging you gets the away message automatically. During business hours, you reply normally (no auto-reply interruption).

Add Multiple Auto-Reply Rules

Powers users create 15-30 rules to handle most common conversations. Here's a starter set:

Keyword	Auto Reply
price / cost / rate	"Our pricing starts at ₹X. Here's a quick overview: [details]. Want me to explain?"
hi / hello / hey	"Hi! Thanks for messaging [Business Name]. How can I help you today?"
delivered / shipping / tracking	"Share your order number and I'll check the status for you! 📦"
open / timing	"We're open [days], [hours]. Visit us at [address] or order online!"
available / stock	"Yes, it's in stock! Want me to reserve one for you? React with YES."
discount / offer / deal	"Current offers: [details]. Use code [X] for extra [Y]% off!"
address / location	"We're located at [full address]. Google Maps: [link]"
catalog / menu / items	"Here's our catalog: [link/image]. Which item interests you?"

Enable AI Auto-Reply (Optional)

WhatsClaw also offers AI-powered auto-reply that generates contextual responses based on the incoming message — not just keyword matching:

Go to "AI Auto Reply" settings
Enable AI for contacts without keyword matches
Set the tone (professional, friendly, casual)
The AI understands context and generates appropriate replies

Best for: When you get varied questions that don't fit keyword patterns. AI handles the edge cases.

Test Your Setup

Before going live, test everything works:

Send a test message from another phone (or ask a friend)
Use your trigger keywords: "price", "hi", "timing"
Check that the auto-reply arrives within seconds
Test during business hours AND after hours
Test with a number NOT in your contacts

If something doesn't reply, check:

Is Accessibility permission still ON? (Android sometimes disables it)
Is the keyword correct? (Check for typos, spaces)
Is WhatsClaw running in background? (Don't force-close it)

Method 2: WhatsApp Business App Auto Reply (Free Built-in)

If you just need a basic away message, WhatsApp Business app's built-in feature works:

Install WhatsApp Business

Download WhatsApp Business from Play Store. You can use it alongside regular WhatsApp (different phone numbers) or migrate your number.

Create a Greeting Message

Go to Business Settings → Greeting Message. This sends automatically to anyone who messages you for the first time (or after 14 days of inactivity).

Example: "Welcome to [Business]! We'll reply soon. Browse our catalog: [link]"

Set Up Away Message

Go to Business Settings → Away Message. Choose:

Who receives it: Everyone / Except contacts / Only contacts
Schedule: Always / Custom hours / Outside business hours
Message text: Your away message

Limitations of WhatsApp Business App Auto Reply:

No keyword-based replies — can't customize based on what customer asks
No AI responses — only static templates
Limited to 1 greeting + 1 away message + quick replies
Quick replies are manual (you tap to send, not automatic)

Pro Tips for Effective Auto Reply

1. Cover the top 10 questions. Analyze your chat history — what do customers ask most? Price, timing, availability, location, delivery, returns. Create rules for all of them.

2. Keep replies conversational. Use the customer's name, add emojis, and write like you'd actually talk. Robotic replies feel like spam.

3. Include a next step. Every auto-reply should guide toward conversion: "Want me to check stock?", "Should I reserve one?", "Call me at [number]".

4. Review and update weekly. New common questions will emerge. Keep refining your rules for better response quality.

5. Don't auto-reply to close contacts. Set up contacts to exclude from auto-reply (family, friends who message casually).

6. Use business hours wisely. Away messages reassure customers you'll respond. Without them, people think you're ignoring them.

FAQ: WhatsApp Auto Reply Setup

Is WhatsApp auto reply legal in India?

Yes, auto-reply is completely legal. It's the same as setting up an email auto-responder. Just ensure you're not sending unsolicited marketing messages (spam). Only auto-reply to people who message you first.

Will I get banned for using WhatsApp auto reply?

No, auto-reply itself doesn't trigger bans. Bans happen when users report you for spam or when you send bulk unsolicited messages. Stick to replying to genuine inquiries and you'll be fine.

Can I use auto reply with regular WhatsApp (not Business)?

Yes, WhatsClaw works with regular WhatsApp, WhatsApp Business, and WhatsApp Business API. You don't need to switch apps.

How many auto reply rules can I create?

With WhatsClaw, you can create unlimited auto reply rules. Start with your top 5-10 most common queries and expand from there.

Does auto reply work when my phone is off?

Auto-reply requires WhatsClaw to be running. If your phone is off or the app is force-closed, replies won't trigger. Keep WhatsClaw running in background (don't force-close it).

Can I customize auto replies based on time of day?

Yes, with WhatsClaw you can set different auto-reply messages for business hours vs. after hours. You can also set different rules for different contacts.

What's the difference between auto reply and AI auto reply?

Auto reply uses fixed rules: if someone says "price", they always get the same pre-written message. AI auto reply generates unique contextual responses based on what the person is asking — more natural but less predictable.

Can I schedule auto reply messages in advance?

Auto-reply is reactive (responds to incoming messages). For proactive scheduling, use WhatsClaw's message scheduler to send at specific times.
