Probabilistic Attribution

What is Probabilistic Attribution?

A tracking method used when click IDs or device identifiers are unavailable. It matches conversions using contextual data like campaign and affiliate IDs.

Why It Is Needed

• Track conversions without click IDs
• Maintain attribution accuracy
• Ensure fair affiliate reporting

How It Works

1. Click URL

https://affclix.org/c?d={domain_id}&c={campaign_id}&a={affiliate_id}&sub_aff6=value

2. Postback URL

https://affclix.org/p?d={domain_id}&privacy=1&auth={auth_token}&sub_adv6=value|campaign_id,affiliate_id

The auth token is your tenant's domain-level security token. The tracker rejects any privacy postback whose auth does not match your domain, preventing spoofed conversions.

3. Matching Logic

• Click data stored with identifiers
• Postback matches via sub IDs
• Fallback to probabilistic when click_id missing
