adattributionkit

What problem does it solve?

AdAttributionKit enables ad networks, publishers, and advertisers to measure installs and re-engagements from iOS ads without exposing user-level identifiers or device-level data, reducing privacy risk while preserving actionable conversion metrics.

Core Features & Use Cases

• Signed impressions and JWS verification: register and validate impressions from ad networks and verify device-sent postbacks server-side to prevent fraud.
• Conversion windows and values: manage fine and coarse conversion values across multiple time windows and lock postbacks to finalize values early.
• Re-engagement and migration: support re-engagement flows with conversion tags and coexistence/migration strategies with SKAdNetwork for publishers and advertisers.
• Use Case: A publisher app registers signed impressions, a server verifies postbacks with Apple public keys and deduplicates by postback-identifier, and the advertised app updates conversion values to trigger timely postbacks.

Quick Start

Use AdAttributionKit to record a signed impression, update the conversion value on first launch, and verify incoming postbacks at your well-known HTTPS endpoint.
