Supercharge Your WhatsApp Marketing with the Conversions API Add-On in DoubleTick
Track, Optimize, and Grow with Data-Driven WhatsApp Campaigns
Are you running Click-to-WhatsApp (CTWA) ads but unsure which campaigns are actually converting? Are you tired of guessing which ads bring in leads and which ones just drain your budget?
It’s time to take full control of your WhatsApp marketing with DoubleTick’s Conversions API (CAPI) — the tool that turns conversations into measurable results.
This guide will help you understand what CAPI is, why it’s a game-changer, and how it can supercharge your WhatsApp campaigns.
What is Conversions API (CAPI)?
Think of CAPI as the ultimate tracking superpower for your WhatsApp campaigns. Unlike the traditional Meta Pixel, which is limited to website activity, CAPI captures customer actions inside or beyond WhatsApp.
This means you can track:
Leads submitted via WhatsApp flows
Consultations booked through chat
Purchases made after interacting with your ad
…and more — all automatically.
With CAPI, you get real, actionable insights about which campaigns are driving revenue and which ones are just wasting money.
Why Do You Need CAPI?
Here’s the problem:
When someone messages you on WhatsApp after clicking your ad, you often don’t know which campaign, ad set, or ad brought them in. That leaves you guessing, and guessing = wasted ad spend.
Benefit #1 — Full Funnel Visibility
With CAPI, every lead and purchase is automatically tied back to the exact campaign. You can finally see:
Which campaigns drive real results
Which campaigns need tweaking or pausing
Your ROI in clear numbers
Here’s a quick comparison:
Conversations Started
✅ Yes
✅ Yes
Leads Submitted
✅ Yes
❌ No
Cost per Lead
✅ Yes
❌ No
Purchases
✅ Yes
❌ No
Cost per Purchase
✅ Yes
❌ No
Return on Ad Spend (RoAS)

❌ No
*Only if purchase value is passed correctly.
Benefit #2 — Smarter Ad Optimisation
Meta’s algorithm uses your CAPI signals to optimise campaign delivery. That means:
Lower Cost per Qualified Lead
Lower Cost per Purchase
Higher ROI, automatically
Your campaigns start working smarter, not harder.
Is CAPI Right for You?
Before diving in:
Are you running Click-to-WhatsApp (CTWA) ads? CAPI only works with CTWA campaigns. If your leads don’t carry a Click ID (clid), Meta will show:
What’s your goal with CTWA ads? Ask yourself:
Are you driving store walk-ins or offline visits?
Are you retargeting warm leads with custom audiences?
Are you converting inquiries to purchases or consultations inside WhatsApp?
Understanding your goal helps you measure what matters most with CAPI.
Why It Matters: Real Examples
1️⃣ E-Commerce Brand – Cosmetics
Without CAPI: 300 conversations started → unclear revenue.
With CAPI: Campaign A drove 80 qualified leads and 15 purchases, Campaign B drove 5 purchases only. Result: Scale Campaign A, pause Campaign B → higher ROI.
2️⃣ Real Estate Agency
Track site visits and appointments from WhatsApp leads.
Campaign X generated 10 site visits from 50 conversations.
Campaign Y generated only 1 visit from 70 conversations. Result: Invest more in high-performing campaigns.
3️⃣ Event Management Company
Track event registrations from WhatsApp leads.
Reduce missed opportunities by following up with leads who started a conversation but didn’t book immediately.
Who Can Use CAPI
E-commerce brands selling products via WhatsApp
Service providers booking consultations or appointments
Retail businesses driving store visits or promotions
High-ticket industries (real estate, jewellery, travel)
Marketing agencies managing client campaigns
⚠️ Works only with Click-to-WhatsApp campaigns.
Real Business Impact
Health & Wellness Brand: Track consultations and sales → Cost per Lead down 40%
