The platform

Everything you need to ship, attribute, and grow.

LinkTrail bundles deep linking, attribution, fraud protection, and analytics into one platform — so you don't stitch together five vendors to answer "where did this install come from?"

Deep Linking

Deferred deep linking that survives the install

Click a link, install the app, and land on the exact screen — promo code, product, profile, anything. LinkTrail bridges the App Store handoff and resolves the deep link on first open.

Smart Routing

One link. Every device. The right destination.

Detect iOS, Android, and desktop in real time. Route to App Store, Play Store, mobile web, or a fallback page — all with the same shareable short link.

Attribution

Multi-signal attribution, deterministic where it counts

A waterfall of Google Play Install Referrer, IDFA, GAID, and fingerprint scoring. Configurable first-touch, last-touch, or linear models per link.

Fraud

Block click flooding and device farms automatically

Every install is scored against velocity, device-signal, and SDK-spoofing heuristics. Suspicious installs are flagged before they ever poison your funnel.

Privacy

AdAttributionKit and SKAdNetwork, first-class

Register for AdAttributionKit and SKAN, push conversion values, ingest postbacks. ATT-aware, privacy-safe, store-policy-clean.

Analytics

A real-time dashboard your growth team will actually use

Clicks, installs, attributed installs, and fraud signals — broken down by campaign, channel, platform, and link. Auto-refreshing, no waiting on cron jobs.

How it works

From tap to attributed install in four steps.

One link does the work of an ad redirector, app-store router, attribution engine, and deep-link resolver — without losing the user along the way.

Create a smart link

Define a deep link path, custom payload, and per-platform fallbacks. Generate a short link or QR code in seconds.

POST /v1/links
{
  "campaign": "summer_launch",
  "channel":  "instagram",
  "iosUrl":   "apps.apple.com/...",
  "androidUrl":"play.google.com/...",
  "deepLinkPath": "/promo/summer",
  "customData": { "code": "SUMMER50" }
}

02
Route every click intelligently
LinkTrail inspects the User-Agent, captures fingerprint signals, and redirects iOS to App Store, Android to Play, desktop to web — no extra logic on your side.
```
GET /l/abc123
↳ iPhone   → apps.apple.com
↳ Pixel 8  → play.google.com
↳ Mac      → linktrail.io/promo
```
03
Match the install to the click
Our attribution waterfall runs Play Install Referrer, IDFA, GAID, and weighted fingerprinting. You get a match type, a confidence score, and clean campaign credit.
```
matchType: "fingerprint"
score:     0.94
campaign:  "summer_launch"
channel:   "instagram"
attributed: true
```
04
Land users on the right screen
On first open, the SDK fires onLink with the path and custom payload. Skip the homepage. Convert users straight into the experience they tapped on.
```
LinkTrail.shared?.onLink { link, _ in
  router.navigate(to: link.path)
  // → /promo/summer · code SUMMER50
}
```

REST + Webhooks: Predictable JSON API. Webhook every attribution event.
Universal & App Links: AASA and assetlinks.json served from your domain.
Privacy-first: AdAttributionKit, SKAdNetwork, ATT-aware flows.

import LinkTrailSDK

// 1. Configure once at launch — the install is tracked automatically.
try LinkTrail.configure(apiKey: "lt_live_…")

// 2. One hook — fires for deferred (first-launch) AND re-engagement links.
LinkTrail.shared?.onLink { link, source in
  router.route(
    to: link.path,             // "/promo/summer"
    customData: link.customData  // ["code": "SUMMER50"]

Attribution & fraud

A waterfall designed for the post-IDFA world.

LinkTrail starts with the most accurate signal available — the Play Install Referrer or an IDFA / GAID match — and only falls back to probabilistic fingerprinting when nothing else applies. Every install comes with a match type and a confidence score so you know exactly what you're looking at.
