WhatsApp Business API Setup in India: Step-by-Step Guide for Small Businesses

WhatsApp Business App vs WhatsApp Business API

The free WhatsApp Business App has a 256-contact broadcast limit, no automation, and no CRM integration. For any business running active marketing, the WhatsApp Business API is the correct option — unlimited broadcasts to opted-in contacts, automated flows, CRM integration, and multi-agent support.

What You Need Before Setting Up

Facebook Business Manager account (Meta Business Suite) with verified business details

A dedicated phone number — cannot be the same as your personal WhatsApp or existing Business App

A business website and email (Meta requires these for verification)

A registered business entity — GST or incorporation documents

A WhatsApp Business Solution Provider (BSP) account — WATI, Gupshup, Twixor, or Interakt

Step 1: Choose Your BSP Platform

WATI — Best for small to mid-size businesses. Good UI, affordable. Starts ~₹2,500/month.

Gupshup — Better for higher volume or custom integrations. More flexible API, steeper learning curve.

Twixor — Enterprise and multi-channel capability. For advanced automation needs.

Interakt — Shopify-native. Best for D2C e-commerce brands on Shopify.

Step 2: Meta Business Manager Verification

Go to business.facebook.com and create or verify your Business Manager account

Add your dedicated phone number in the WhatsApp Manager section

Complete business verification — upload required documents

Step 3: Create and Submit Message Templates

WhatsApp API only allows pre-approved templates for outbound messages. Templates must be submitted to Meta — typically 24–48 hours for approval. Categories: utility (order updates, reminders), authentication (OTPs), and marketing (promotional messages).

Step 4: Build Your First Automated Flow

Start simple: a 3-message cart recovery sequence or post-purchase follow-up flow

Set trigger: customer abandons cart → wait 1 hour → send Message 1

Message 1: Remind. Message 2 (24 hours): Add a reason. Message 3 (48 hours): Add urgency if appropriate.

Step 5: Grow Your Opt-In List

WhatsApp API only allows messaging opted-in contacts. Collect opt-ins at checkout, on your website, through Instagram DMs, and at physical touchpoints via QR code. Do not add people without consent — WhatsApp can block accounts for spam reports.
