First-party data capture

Capture the conversion data that pixels can’t reach

Server-side tracking works where browser-based pixels fail. Your conversion data stays complete regardless of ad blockers, iOS privacy settings, or cookie deprecation.

  • Server-to-server tracking collects more signals compared to pixels
  • First-party data capture works even with ad blockers and VPNs
  • Every conversion event is recorded directly from your backend
  • No dependency on third-party cookies

Signal enrichment & normalization

Send each platform enriched data in the format it expects

Each conversion signal is enriched with first-party customer and transaction data, then normalized to match the specific API requirements of each ad platform. Enriched and properly formatted signals mean higher match quality and smarter optimization.

  • Signals enriched with customer parameters and transaction details
  • Platform-specific normalization for Meta, Google, TikTok, Snapchat, Bing
  • Designed to improve Event Match Quality score by sending enriched data
  • Deduplication prevents double-counting when pixel and server both fire

Better platform learning

Give ad algorithms the data they need to find your best customers

When platforms receive more complete, properly formatted signals, their optimization models operate with fewer blind spots. As a result, their algorithms learn faster and optimize better for your needs.

  • Platforms build better audience models from complete conversion data
  • Spend your budget on audiences that actually convert, not on guesses
  • Reduced gap between platform-reported and actual results
  • Confidence to scale spend knowing the feedback loop is working

Why Conversion API matters in 2026

Your ad platforms burn budget by optimizing on incomplete data

Privacy changes, ad blockers, and cookie deprecation prevent traditional pixels from sending conversion events back to your platforms. Each missing signal makes campaign optimization less effective and reduce your profit margins.

Icon

Broken pixel tracking

Privacy restrictions, iOS changes, and ad blockers prevent browser-based pixels from capturing conversion events. Platforms don’t see what actually happened.

Icon

Incomplete optimization signals

When platforms receive partial data, their algorithms target less relevant audiences and allocate budget based on an incomplete picture of what’s working.

Icon

Growing signal gap

The more conversions go unreported, the wider the gap between platform-reported performance and reality. Scaling decisions become guesswork.

Conversion API isn’t about adding another integration.
It’s about restoring the data connection your ad platforms need to work properly.

Conversion API integrations

Built for the platforms where your spend happens

RedTrack maintains dedicated Conversion API integrations for each major ad platform. Each one is built to match that platform’s specific data format, field requirements, and event configuration.

Icon

Meta Conversions API

Send enriched conversion events directly to Meta’s servers. RedTrack maps your purchase, lead, and custom events to Meta’s required parameters, maximizes Event Match Quality, and deduplicates with pixel events automatically.

Icon

TikTok Events API

Deliver server-side conversion data to TikTok in their required format. RedTrack normalizes your events to TikTok’s schema, supports multiple pixel IDs, and ensures conversion signals reach TikTok’s optimization engine reliably.

Icon

Snapchat Conversions API

Connect your conversion data to Snapchat’s server-side API. RedTrack formats events to Snapchat’s specifications, passes enriched customer parameters, and keeps signal delivery consistent alongside your other platform integrations.
