Click to WhatsApp Ads: Setup Guide for Indian Businesses

How to set up click to WhatsApp ads on Facebook and Instagram, use the free 72-hour window, qualify leads in chat and track conversations through to sales.

Published 11 July 2026 by Web Hippo in Paid Ads

Click to WhatsApp ads (Meta also calls them "ads that click to WhatsApp", and agencies shorten it to CTWA) are Facebook and Instagram ads with a button that opens a WhatsApp chat with your business instead of a website or a form. For Indian buyers, who already live on WhatsApp, that is often the shortest path from "interested" to "talking to you".

The ads themselves are easy to launch. What decides whether they make money is everything after the tap: the first message, how fast you reply, how you qualify the lead and whether you can trace a chat to a sale. This guide covers setup in Meta Ads Manager, the app vs API choice, the free 72-hour messaging window, a first-reply script for three Indian businesses and a table for choosing between WhatsApp, lead forms and your website.

What Are Click to WhatsApp Ads?

A click to WhatsApp ad is a normal Meta ad (image, video or carousel) whose call-to-action button, usually "Send WhatsApp message", opens WhatsApp on the viewer's phone with a chat to your business number already started. The person can send the pre-filled first message as it is or edit it. From that moment you have a real conversation with a real phone number.

According to WhatsApp's own setup guide, the ads run on Facebook and Instagram placements such as feeds, stories and Facebook Marketplace. You buy them through the same Ads Manager and budget as the rest of your Meta campaigns, so the cost per 1,000 impressions follows the ranges in our Facebook ads cost guide.

The short version CTWA ads trade some volume for intent. Fewer people start a chat than would tap "Submit" on a pre-filled lead form, but the ones who do are usually reachable, responsive and already asking a question. They only pay off if someone (or a well-built bot) answers within minutes.

WhatsApp Business App or WhatsApp Business Platform?

Both can receive chats from click to WhatsApp ads. The difference is what happens after the chat starts. The WhatsApp Business app is the free phone app most small businesses already use. The WhatsApp Business Platform (often called the WhatsApp API) connects your number to software, usually through a Business Solution Provider (BSP) such as a chatbot or CRM vendor.

Our view: start on the app if you are testing the channel with a small budget and can personally answer within ten minutes during ad hours. Move to the Platform when chats pile up faster than one phone can handle, or when you want Meta to optimise for leads that actually buy. Our WhatsApp marketing playbook covers the wider app-vs-API decision.

How to Set Up Click to WhatsApp Ads in Meta Ads Manager

Before you start, link your WhatsApp Business number to the Facebook Page that will run the ads. Without that link, WhatsApp will not show up as a destination. Then follow the flow WhatsApp documents for Ads Manager:

  • <strong>1. Create a campaign</strong> in Ads Manager and choose an objective (see the table below).
  • <strong>2. At the ad set level, set the conversion location</strong> to Messaging apps, then select WhatsApp and the linked number.
  • <strong>3. Choose the performance goal</strong>, typically maximising the number of conversations.
  • <strong>4. Set budget, schedule and audience.</strong> WhatsApp's guide suggests running for at least seven days so delivery can settle.
  • <strong>5. Build the ad and the message template.</strong> Upload creative, write the copy, and set the greeting and pre-filled message people will see when WhatsApp opens.
  • <strong>6. Test on a real phone</strong> using the ad preview, then publish.

Which objective to choose

Meta's developer documentation for click to WhatsApp ads lists four objectives that can send people to WhatsApp: Engagement, Leads, Sales and Traffic. Ads Manager labels move around, but the choice works like this:

If you are new to CTWA, run Engagement optimised for conversations for the first few weeks. Switch to Sales only when enough purchase events are coming back for Meta to learn from; otherwise the campaign sits in the learning phase and costs stay high.

The Free 72-Hour Window for Chats from Ads

On the WhatsApp Business Platform, chats that start from a click to WhatsApp ad (or a Facebook Page call-to-action button) get special pricing treatment. Per Meta's pricing documentation, if you reply within 24 hours of the customer's message, that reply is free and a <strong>free entry point window</strong> opens. For the next 72 hours you can send any type of message to that person, templates included, at no Meta charge.

  • <strong>Reply inside 24 hours</strong> or the free window never opens. A slow first reply costs you money as well as the lead.
  • <strong>The 24-hour customer service window still applies.</strong> If the customer goes quiet for 24 hours, you can only send templates, but those templates remain free until the 72 hours run out.
  • <strong>It applies to chats started on the WhatsApp mobile app</strong> on Android or iOS, which covers almost all Indian users.
  • <strong>The Business app has no per-message charges anyway</strong>, so the window matters only on the Platform.

This window is the main reason CTWA ads fit the October 2026 pricing change, when Meta began charging for ordinary service replies. We won't repeat the rate card here; our WhatsApp Business API pricing guide has the current Indian rates and a worked monthly cost example.

Pre-Filled Messages and Ice Breakers

The first message is set by you, not the customer. A good pre-filled message does two jobs: it tells your team (or bot) which ad the person came from, and it gives the customer something easy to send. "Hi, I saw your ad for aligners in Kukatpally. Is the ₹499 consultation still on?" beats a generic "Hi".

On the Platform you can also add <strong>ice breakers</strong>: tappable questions shown the first time someone opens a chat with you. Meta's conversational components documentation allows up to four per number, 80 characters each, with no emoji. The same page notes that when a chat opens with pre-filled text from a link, WhatsApp dismisses the ice breakers. So decide which one you are relying on for each ad, and check the result on a phone before you spend.

Rules we follow for the first message

  • Mention the offer or service from the ad, so the chat has context and you can tell campaigns apart.
  • Keep it one line. People edit long messages or abandon them.
  • Use the language of the ad. A Telugu creative should open a Telugu or bilingual chat.
  • Never promise something in the ad that the first reply can't deliver, such as a price you will only share on a call.

First-Reply Scripts and a Qualification Flow

Most CTWA campaigns we audit lose leads in the first five minutes, not in the ad. The fix is a written first reply and three or four qualifying questions, answered with quick-reply buttons where possible. Here is the same structure applied to three businesses. The names and offers are illustrative.

Example 1: a dental clinic in Kukatpally

  • <strong>Reply 1 (instant):</strong> "Hi! This is Smile Studio, Kukatpally. Thanks for asking about aligners. May I ask 3 quick questions so the doctor can advise you properly?"
  • <strong>Q1:</strong> "What would you like help with?" [Crooked teeth] [Gaps] [Not sure]
  • <strong>Q2:</strong> "Have you had braces or aligners before?" [Yes] [No]
  • <strong>Q3:</strong> "When would you like to visit?" [This week] [This month] [Just exploring]
  • <strong>Hand-off:</strong> "This week" and "This month" go to the front desk to book a slot. "Just exploring" gets a before-and-after guide and a follow-up inside the free window.

Example 2: a 3BHK project near Kokapet

  • <strong>Reply 1:</strong> "Thanks for your interest in Green Arc, Kokapet. I can share the brochure and floor plans right away. A couple of questions first?"
  • <strong>Q1:</strong> "Which configuration?" [3BHK] [3.5BHK] [Just browsing]
  • <strong>Q2:</strong> "Your budget range?" [Under ₹1.5 Cr] [₹1.5–2 Cr] [Above ₹2 Cr]
  • <strong>Q3:</strong> "When are you planning to buy?" [0–3 months] [3–6 months] [Later]
  • <strong>Hand-off:</strong> send the brochure to everyone. Budget-matched buyers within 6 months get a site-visit offer and a named sales manager's call.

Example 3: NEET coaching in Vijayawada

  • <strong>Reply 1:</strong> "Hi! Welcome to Apex Academy. Are you a student or a parent?" [Student] [Parent]
  • <strong>Q1:</strong> "Which class is the student in now?" [Class 11] [Class 12] [Dropper]
  • <strong>Q2:</strong> "Preferred mode?" [Classroom] [Online] [Hybrid]
  • <strong>Q3:</strong> "Would you like to attend a free demo class?" [Yes, this weekend] [Send details first]
  • <strong>Hand-off:</strong> demo bookings go to the counsellor with the answers attached, so the first call starts from what the parent already said.

On the Business app you can approximate this with a greeting message plus saved quick replies and labels such as "Hot", "Site visit" and "Not now". On the Platform the flow runs automatically and the answers land in your CRM. Before you send promotional messages later, ask for permission in the chat and record it; our DPDP checklist for marketers explains why that consent record matters.

Measuring Click to WhatsApp Ads: From Chat to Sale

Ads Manager reports <strong>messaging conversations started</strong> and <strong>cost per messaging conversation started</strong>. Those numbers tell you whether the ad is getting chats. They say nothing about whether the chats were any good, and a campaign that looks cheap per conversation can be expensive per customer.

To close that gap on the Platform, use Meta's Conversions API for business messaging. Every message that comes from an ad carries a click ID (<code>ctwa_clid</code>) in its referral data. When that chat later becomes a qualified lead or a purchase, your CRM or BSP sends the event back to Meta with the click ID, <code>action_source</code> set to "business_messaging" and <code>messaging_channel</code> set to "whatsapp". Supported events include LeadSubmitted, QualifiedLead and Purchase, and Meta says this is what makes purchase optimisation possible for click to WhatsApp ads.

On the Business app you can't send events back, so keep it simple: label every chat with its campaign, count qualified leads and sales weekly in a sheet, and divide ad spend by each. It is manual, but it is still far better than judging the campaign on conversations alone.

CTWA vs Lead Form vs Website: Which to Use

Click to WhatsApp ads are not automatically the best lead ad. Here is how we choose between the three main destinations for Indian clients.

Common Mistakes with WhatsApp Ads

  • <strong>Running ads when nobody is on the phone.</strong> Schedule ads for staffed hours or put a bot on the first reply.
  • <strong>A generic "Hi" as the pre-filled message.</strong> You lose the context of which ad and offer brought the person in.
  • <strong>Asking for everything at once.</strong> Name, email, budget, location and timeline in one message reads like a form and gets ignored.
  • <strong>Pushing a phone call immediately.</strong> Many people chose WhatsApp precisely because they didn't want a call yet. Ask first.
  • <strong>Judging on cost per conversation.</strong> Track qualified leads and sales, as above.
  • <strong>Broadcasting to ad leads without consent.</strong> A chat is not permission for weekly promotions.
