WhatsApp chatbot for business in India: the complete guide

Updated 2026-10-22 · 6 min read · By the Convo360 team

What a WhatsApp chatbot actually is

A WhatsApp chatbot is software connected to the WhatsApp Business API that reads incoming messages and replies automatically, with fixed menus, AI-generated answers, or both. It sits between your customer and your team: answering catalogue questions at 11 PM, confirming a booking, or collecting a lead before a salesperson calls.

For an Indian business this matters because WhatsApp is where the conversation already happens: a customer messaging "showroom timing?" or "order kaha hai?" expects a reply in minutes, not a support ticket. A chatbot on the WhatsApp Business API gives you that reply instantly, around the clock, without adding headcount for every conversation.

It is not a single product you buy from Meta. Meta owns the API and the messaging rails; a platform like Convo360 sits on top with the flow builder, AI agent, contacts, CRM and reporting you actually use day to day. Understanding that split early saves confusion later when you're comparing vendors: see what is the WhatsApp Business API for the underlying mechanics.

API vs app: which one do you need

The free WhatsApp Business app is fine for one person replying manually from a phone. The moment you want automated replies, a team inbox, broadcast campaigns or approved templates, you need the WhatsApp Business API, accessed through a platform like Convo360, not directly from Meta.

Coexistence lets you keep using the familiar app alongside the API on the same number, so your team isn't forced to relearn a new interface on day one. This is the easiest upgrade path for a business that already has an active number with chat history and saved contacts.

What businesses actually use it for

Across Indian industries the pattern repeats: deflect repetitive questions, capture the lead before it's lost, and remind people before they forget. Common jobs:

• D2C and retail: order status, catalogue browsing, abandoned cart recovery and stock enquiries.
• Clinics and salons: appointment booking and reminders, cutting no-shows without extra front-desk staff.
• Real estate: instant callback on a new enquiry and site-visit scheduling.
• Coaching and edtech: admission enquiries and demo class bookings.
• Restaurants and QSR: table reservations and takeaway orders.
• NBFCs and lenders: EMI reminders and loan eligibility screening before a human ever gets involved.

Most businesses start with a single flow, the one question they get asked most, then add more once they see what customers actually type in.

AI replies vs guided flows: choosing the right mix

Not every message needs an AI model to answer it. A guided (no-AI) bot uses fixed buttons and menus for predictable questions, such as "Track my order", "Store hours" or "Book a call", and needs no AI key at all, which keeps it fast, predictable and free of hallucination risk.

An AI Reply node earns its place for open-ended questions where a menu can't cover every phrasing, such as "Does this saree come in a lighter shade?" or "Can I get an EMI plan for a used bike?". Feed it a knowledge base of your product PDFs or FAQ page so it answers from your actual catalogue instead of guessing. Most working flows on Convo360 mix both: buttons for the top three intents, then an AI Reply as the fallback for everything else. See AI bot vs rule-based chatbot and what is a guided bot for more on when each wins.

What it costs in India

Two separate bills apply. First, a platform fee to the chatbot provider for the flow builder, AI agent, inbox and automation: on Convo360 this starts at ₹999/month (Starter, ex-GST) for WhatsApp + Web chat, going up to ₹2,999 (Pro) for AI voice calls and integrations, and ₹7,999 (Business) for the REST API and unlimited team seats. Second, Meta's own per-message charges, billed per delivered message by category (utility, marketing, authentication and, from 1 October 2026, service replies after a free monthly tier) and paid directly to Meta at their published rates.

Convo360 runs on the second model, BYOK (Bring Your Own Keys): you connect your own WhatsApp number and, for AI replies, your own OpenAI, Anthropic or Google Gemini key, so there's no markup added on top of what Meta or the AI provider charges you directly. Read the full breakdown in our WhatsApp chatbot pricing guide, the BYOK explainer and the wider cost anatomy post.

Setting it up on Convo360, and mistakes to avoid

1. Sign up at aiagent.convo360.ai/register: 14-day free trial, no card needed.
2. Connect your WhatsApp number through embedded signup (or turn on Coexistence to keep the app running alongside it).
3. Pick a ready-made agent from the Template Store for your industry, or start blank in the Flow Builder.
4. Add blocks: Send Message, Buttons or List Menu for structured choices, and an AI Reply node with a short system prompt for open questions.
5. Set a keyword trigger (like "price" or "book") or leave it on "new conversation".
6. Use Preview / Try-it to test the flow end to end, then publish.

Upload a few PDFs or your FAQ page to the agent's knowledge base and it can answer product questions without you writing every reply by hand. Full steps are in Getting Started and Flow Builder docs.

A few mistakes catch out first-time launches. Skipping the knowledge base leaves an AI Reply node with no source material, so it either goes silent or guesses; always attach your FAQ or catalogue. Skipping Preview / Try-it lets a flow that looks fine on paper dead-end on a real reply, so run health checks before publishing. Sending marketing templates to unopted contacts gets templates rejected or numbers flagged, so always capture consent first. Ignoring the human hand-off leaves a frustrated customer stuck, so keep a live-chat team inbox with human takeover one click away. Finally, choosing a platform on price alone misses the bigger picture; compare the full pricing model, not just the sticker price, using our buyer's checklist.

Compliance you can't skip

Meta requires opt-in before you message someone outside an active conversation, template approval for anything sent as a broadcast, and respects a strict 24-hour customer-service window after a customer's last message; outside it, only an approved template can restart the chat. Marketing templates need explicit consent; utility templates (like an order update) don't. Never ask a customer for an OTP, full card number or password inside WhatsApp; no legitimate bot should.

See Compliance docs, the 24-hour window explainer and Meta's own WhatsApp Business Policy for the full rules before your first broadcast.
