Without 1STEP Attribution

✗ Spending $5k/month on ads with no idea what's working
✗ Meta says 100 sales. Shopify shows 60. You don't know who to trust
✗ iOS 14.5+ broke pixel tracking — attribution data is 40% incomplete
✗ Fraud bots burning 15% of your ad budget
✗ Conversion lag means decisions are based on 3-day-old data

With 1STEP S2S Attribution

✓ Every conversion matched to the exact channel and creative that caused it
✓ Single source of truth — one dashboard for all platforms
✓ S2S works independently of browser cookies or mobile identifiers
✓ Fraud detection blocks invalid traffic before it hits your budget
✓ Real-time data — see conversions within seconds of them happening

Core Features

Attribution built for the post-cookie world.

Privacy-Safe S2S Tracking

Events fire from your server directly to ours — no browser, no SDK, no cookie. GDPR and CCPA compliant out of the box. Works perfectly after iOS 14.5 and third-party cookie deprecation.

Real-Time Dashboard

See every conversion within seconds. ROAS by channel, campaign, and creative — all in one place. No more reconciling Meta, Google, and TikTok numbers in separate tabs.

Fraud Prevention

Automatically flag and block invalid traffic — bot installs, click spamming, device emulators — before it consumes your budget. Average SMB saves 12-18% on ad spend after enabling fraud protection.

Technical Overview

How S2S works.

Server-to-server attribution is simpler than it sounds. Here's what happens when a customer converts.

Customer clicks an ad

A unique click ID is generated by the ad platform (gclid, fbclid, ttclid). We capture this ID and store it server-side — no browser storage needed.

Customer converts on your site

Purchase, sign-up, or any custom event fires. Your server sends the conversion event (with the click ID) directly to our S2S ingestion endpoint.

We match and route the conversion

1STEP matches the click ID to the originating ad, campaign, and channel. The conversion data flows to your dashboard and (optionally) back to the ad platform's conversion API.

You see the full picture

Real-time ROAS, cost-per-acquisition, and multi-touch attribution across all channels — in one dashboard. Make budget decisions with confidence.
