Powering privacy-first performance for advertisers
October 2, 2025
Discover how privacy compliance and performance can work hand-in-hand with carsales CAPI
Browser changes, privacy regulations, and evolving consumer expectations are reshaping how brands connect with potential buyers. As traditional tracking methods continue to fade, forward-thinking advertisers are discovering that privacy compliance and performance can work hand-in-hand through smarter solutions.
Signal loss is impacting your campaigns today
It’s no secret that those detailed conversion reports that advertisers relied on are showing gaps, the retargeting campaigns that used to run flawlessly are missing chunks of your audience. Safari users are disappearing from attribution reports after 7 days and Chrome conversions are becoming harder to track.
For advertisers in the mobility space, where customers research for weeks if not months before walking into a dealership, these blind spots really hurt. You're still driving valuable actions: test drives, brochure downloads, finance applications. But you can't see which campaigns deserve the credit. Making smart budget decisions becomes guesswork when you can't connect the dots between ad exposure and showroom visits.
CAPI: Privacy compliance that enhances performance
carsales Conversions API (CAPI) bridges the gap between privacy and performance. CAPI creates a secure connection between carsales advertising and your website activity, capturing the complete customer journey whilst maintaining full privacy compliance.
So how does it work? When users interact with your carsales ad then visit your website within 30 days, CAPI captures that journey through AdFixus's secure data clean room. Meaning that information is matched and analysed without third-party cookies.
This intelligence flows directly into Ignition, carsales' self-serve ad platform. Within Ignition's dashboard, you see exactly how your carsales campaigns drive website actions. Real-time attribution reports update automatically, giving you visibility to optimise campaigns instantly. Every audience segment, targeting parameter, and performance metric lives within Ignition's unified interface.
Three core capabilities that are unlocked via carsales CAPI include:
Enhanced Measurement
Ignition displays website actions attributed directly to specific carsales campaigns. Track brochure downloads, finance calculator interactions, test drive bookings, and quote requests connected to their originating ads. The attribution dashboard presents real-time data, allowing budget shifts toward campaigns driving valuable actions. The 30-day attribution window captures the full automotive consideration journey.
Advanced Targeting
Through Ignition's audience builder, deploy AI-powered predictive audiences identifying high-intent shoppers based on carsales browsing and your website behaviour. Create lookalike audiences modelled on your best customers with a few clicks. Set up remarketing campaigns that re-engage website visitors directly through carsales inventory. These native features activate through the same interface where you manage campaigns.
Responsible Data Sharing
AdFixus-powered clean room technology enables cross-platform insights whilst respecting user privacy. As an Australian partnership, carsales and AdFixus maintain the highest local data privacy standards. Within Ignition, activate audiences and track performance knowing every data point follows privacy-first principles.
CAPI in action
Leading advertisers already using CAPI are experiencing the transformation first-hand. Nicholas Johnson, Head of Growth at Adtorque Edge, reports: "carsales CAPI is giving us real-time insights into test drive bookings and vehicle reservations, strengthening our understanding of ROI. We are achieving exceptional conversion results, transforming how retailers connect with high-intent buyers."
Once CAPI is activated, enhanced measurement and targeting capabilities appear automatically in your Ignition dashboard.
Your competitive advantage starts here
