Click-to-WhatsApp Ads — The Complete India Playbook

Why CTWA crushes other ad formats in India

When an Indian customer taps a Click-to-WhatsApp ad on Facebook or Instagram, they land directly inside a WhatsApp chat with your business — bypassing landing pages, form abandonment and email follow-up. Meta makes the first 72 hours of that conversation free, which means your effective acquisition cost is just the ad spend itself. Combined with VibeFlow chatbots that qualify and convert leads automatically, CTWA routinely delivers 3–7× the ROI of traditional Facebook lead ads in India.

How CTWA actually works

Ad on Facebook / Instagram

A standard Meta ad with a 'Send Message' or 'Chat on WhatsApp' CTA button instead of 'Learn More'.

One tap → WhatsApp chat

User taps the ad and lands inside a WhatsApp chat with your business — no app install, no form, no friction.

Free 72-hour window

Meta charges nothing for the WhatsApp conversation portion for the first 72 hours of the conversation. You pay only the ad cost.

Chatbot qualifies

VibeFlow chatbot greets, qualifies (budget, location, intent) and books a callback or completes the sale automatically.

Reporting in dashboard

See ad-to-conversation, conversation-to-lead and conversation-to-customer in one Mappstore report.

Frequently asked questions

What is the cost of a Click-to-WhatsApp ad in India?

You pay Meta the standard ad cost (CPC/CPM auction) — typically ₹4–₹25 per click in India depending on industry and targeting. The WhatsApp conversation that follows is FREE for the first 72 hours, making CTWA dramatically cheaper than equivalent landing-page funnels.

Is the 72-hour free window really free?

Yes — when a conversation originates from a CTWA ad it qualifies as a 'free entry-point conversation' for the first 72 hours. After 72 hours, normal per-message rates apply if you continue messaging that user.

Do I need WhatsApp Business API for CTWA?

Yes. Meta requires a WABA-connected number to receive CTWA traffic. Mappstore handles WABA onboarding in 15 minutes.

Can I run CTWA without a chatbot?

Technically yes — you can manually reply to every chat. In practice the volume from a real campaign is overwhelming without VibeFlow AI to qualify, route and respond automatically.

What objectives work best for CTWA?

'Engagement' and 'Sales' objectives with 'Messages' as the conversion event work best. Avoid 'Traffic' — it sends low-intent clicks.

How do I target the right audience?

Start with interest-based lookalikes of your existing WhatsApp conversation customers. Layer geo (city/pincode), age, language and behavioural signals. Mappstore's Meta Marketing API integration lets you build and launch these audiences from inside the dashboard.

What creative format converts best?

Single-image ads with a clear product/service photo, 1 line of headline, a benefit and a strong 'Chat now' CTA outperform video for first-time CTWA campaigns. Test square (1:1) and vertical (4:5) formats.
