How to Set Up WhatsApp Business API in India (Step-by-Step 2026)

What You Need Before You Start

Setting up the WhatsApp Business API used to require a Meta Partner and weeks of waiting. With Waptrix, you can do it yourself in under 30 minutes. Here's what you need:

• A Facebook Business Manager account (free at business.facebook.com)
• A phone number that is NOT already registered on WhatsApp (personal or business)
• Business details: name, address, website, category
• An Indian business (or a business operating in India)

The phone number you use must not be registered on WhatsApp already. If it is, you'll need to delete that WhatsApp account first.

Step 1: Create a Facebook Business Manager Account

Go to business.facebook.com and sign up. Enter your:

• Business name (as it appears on legal documents)
• Your name
• Business email address

Verify your email and complete business verification. This involves uploading a business document (GST certificate, shop registration, or utility bill in your business name).

Step 2: Create a WhatsApp Business Account (WABA)

Inside Facebook Business Manager:

1. Go to Business Settings → Accounts → WhatsApp Accounts
2. Click Add → Create a WhatsApp Business Account
3. Name your WABA (this appears to customers as your display name)
4. Accept the WhatsApp Business terms of service

Step 3: Add Your Phone Number

1. Inside your WABA, go to Phone Numbers → Add Phone Number
2. Enter the number you want to use for WhatsApp Business
3. Choose verification method: SMS or Voice call
4. Enter the 6-digit verification code

Your number is now verified and connected to the WhatsApp Business API.

Step 4: Connect to Waptrix

1. Sign up at app.waptrix.in
2. Go to Settings → Connect WhatsApp
3. Click Connect via Meta — this opens Meta's OAuth flow
4. Select your Facebook Business Manager account
5. Select the WABA you created in Step 2
6. Select your phone number
7. Click Authorize

Waptrix automatically subscribes your WABA to the necessary webhooks and imports your phone number settings.

Step 5: Create Your First Template

Before you can send bulk messages, you need at least one approved template.

1. Go to Settings → Templates in Waptrix
2. Click New Template
3. Choose category: Marketing, Utility, or Authentication
4. Write your template body. Use {{1}}, {{2}} for variables
5. Add a header image if needed
6. Add buttons (Quick Reply or URL)
7. Click Submit to Meta

Meta reviews templates within 24 hours. You'll receive an email when approved.

Step 6: Import Your Contacts

1. Go to Contacts in Waptrix
2. Click Import CSV
3. Upload your contacts file with columns: name, phone, email (optional)
4. Map the columns
5. Create a Segment to group contacts (e.g., "Mumbai Customers", "VIP buyers")

Make sure every contact has explicitly opted in to receive WhatsApp messages from you.

Step 7: Launch Your First Campaign

1. Go to Campaigns → Create Campaign
2. Select your approved template
3. Select your contact segment
4. Set send time (now or scheduled)
5. Click Launch

Waptrix handles the sending, tracks delivery, and updates you with real-time stats.

Common Setup Mistakes to Avoid

Mistake 1: Using a number already on WhatsApp

You'll get an error during verification. Delete your existing WhatsApp account on that number first (Settings → Account → Delete My Account).

Mistake 2: Business name mismatch

Your WABA display name must match your business name. Meta rejects names that look like spam.

Mistake 3: Skipping Business Verification

Without Business Verification, you're stuck at Tier 1 (1,000 messages/day). Complete verification to unlock higher limits.

Mistake 4: Using prohibited template language

Marketing templates can't contain certain phrases. Read Meta's template guidelines before writing.

What Happens Next

Once you're set up, you can:

• Send broadcast campaigns to thousands of contacts
• Set up automated responses for common questions
• Create multi-step drip sequences
• Track delivery, read, and response rates
• Manage all customer conversations in one inbox
