Click-to-WhatsApp Ads (CTWA)
Click-to-WhatsApp Ads (CTWA) are Facebook and Instagram ads whose call-to-action opens a one-to-one WhatsApp chat with your business instead of sending the user to a website or lead form. When someone taps "Send Message" on the ad, a WhatsApp conversation launches with a pre-filled greeting, and your business receives that inbound message through the WhatsApp Business API — where you can qualify, answer, and convert the prospect in real time. For Indian businesses that already do most of their selling over chat, CTWA collapses the gap between an ad impression and a live sales conversation, replacing the leaky landing-page-then-callback funnel with an instant, trackable thread.
In one line
CTWA are Meta ads (Facebook/Instagram) whose button opens a WhatsApp chat instead of a webpage, turning ad clicks into live conversations on the WhatsApp Business API. The customer's first message is free to reply to inside the 24-hour service window; any business-initiated template you send afterward is billed per delivered message by category.What Click-to-WhatsApp Ads actually are
A Click-to-WhatsApp Ad is an ordinary Meta ad — image, video, carousel, or Reels format — created in Ads Manager with the conversation objective and a 'Send Message' button pointed at WhatsApp. The difference from a normal ad is entirely in the destination: instead of a URL, the click deep-links into WhatsApp and opens a fresh thread with your WhatsApp Business number. Meta attaches a hidden referral object to that first inbound message, so your platform knows precisely which ad, ad set, and campaign drove the conversation. Because the customer messages you first, the exchange opens inside a 24-hour customer service window during which your replies are free-form and free of per-message charges.
- Runs across Facebook feed, Instagram feed and Stories, Reels, Messenger, and Audience Network placements
- Uses Meta's standard conversion/engagement objectives — no separate ad product to learn
- Deep-links to a specific WhatsApp Business number, opening a real API-backed thread
- Carries a referral payload (headline, source ad ID, click text) into your webhook for attribution
Why CTWA matters for Indian businesses
In India, WhatsApp is where buying decisions actually happen — customers prefer to ask a quick question over chat rather than fill a form and wait for a callback. CTWA meets that behaviour head-on. Landing pages lose a large share of paid traffic to slow loads, form friction, and abandoned carts; a chat thread loses far fewer, because the customer is already talking to you. You also capture a verified mobile identity and an opted-in contact from the very first message, which is worth more than an anonymous form fill. For sectors like education, real estate, D2C, healthcare, and local services, that means warmer leads, faster response times, and a conversation you can pick back up later with a template message rather than a cold call.
- Higher intent: the customer chose to start a conversation, not just click a link
- Instant qualification by a human agent or an automated flow, 24×7
- A re-engageable contact you own — not a one-time page visit
- Native fit for catalogue browsing, price enquiries, and appointment booking
How CTWA works end to end
The flow is short and mechanical. You build the ad in Meta Ads Manager, choose WhatsApp as the message destination, and optionally set a greeting and up to a few frequently-asked-question prompts. When your ad is served and a user taps the CTA, WhatsApp opens with your pre-filled message; the moment they send it, your WhatsApp Business API account receives an inbound webhook containing both the message and the CTWA referral data. From there your platform routes the thread to a team inbox, a chatbot, or an automated qualifying flow. Everything the agent or bot sends back within 24 hours of that inbound message is a free service reply. If you need to follow up after the window closes — a quote the next morning, an offer a week later — you send a pre-approved template, which is billed per delivered message by its category.
- Build the ad with the conversation objective and a WhatsApp destination
- Customer taps 'Send Message' → WhatsApp opens with your greeting pre-filled
- Their first message hits your API webhook with the CTWA referral attached
- You reply free within the 24-hour service window via inbox, bot, or flow
- Follow-ups after 24 hours use approved templates, billed per delivered message
What CTWA costs you
CTWA has two distinct cost layers, and confusing them is the most common budgeting mistake. The first layer is your Meta ad spend — the cost per result you pay to Ads Manager for impressions and clicks, set by your bids and auction. The second layer is WhatsApp messaging on the API. Since Meta moved off per-conversation billing on 1 July 2025, WhatsApp bills per delivered message by category — marketing, utility, or authentication. Crucially, the customer-initiated conversation that a CTWA click creates opens a 24-hour service window in which your replies are free; you only incur WhatsApp charges when you proactively send a template message (typically a marketing or utility follow-up after the window). Through InfiQ, those template charges are transparent ₹ pricing (ex-GST), so you can forecast the messaging side of a campaign as cleanly as the ad side.
- Ad layer: standard Meta cost-per-result from the auction
- Messaging layer: WhatsApp charges per delivered message by category
- The CTWA inbound opens a free 24-hour service window for your replies
- You pay WhatsApp only when you send a business-initiated template later
Common mistakes to avoid
Teams new to CTWA usually stumble in a handful of predictable ways. The biggest is treating the ad like a landing page and then going silent — a CTWA click is a live person expecting an answer, so a slow or missing first reply wastes the ad spend entirely. Another is assuming every message is free because the first replies are: the 24-hour service window only covers responses to a customer-initiated thread, and any proactive follow-up needs an approved template that is billed. Others forget to build an automated first response for after-hours clicks, ignore the referral payload and lose all campaign attribution, or point ads at a number that is not properly connected to the WhatsApp Business API. Finally, some businesses run CTWA on a personal or unverified number and then hit ownership and scaling limits — CTWA should always run on a verified API number inside a Business Manager you control.
- Not answering fast — the click is a live prospect, not a form fill
- Confusing the free 24-hour service window with free template follow-ups
- No after-hours auto-reply, so late-night clicks go cold
- Ignoring the referral payload and losing ad-to-conversation attribution
- Running ads on an unverified number instead of a properly owned API number
