Tracking Methods & Technologies

Server-to-Server (S2S) Postback Tracking

S2S tracking is the most reliable method available. When a conversion happens, your server sends a postback directly to the tracking platform with the click ID and conversion details. No browser involvement means no cookie restrictions, no ad blockers, and no cross-device attribution issues.

How S2S Postbacks Work

  • 1. User clicks affiliate link -- click ID is generated and passed to your landing page
  • 2. Your site stores the click ID (in session, database, or URL parameter)
  • 3. User converts (signup, deposit, purchase)
  • 4. Your server fires a postback URL to the tracking platform with the click ID
  • 5. The platform matches the conversion to the original click and calculates commission

UTM Parameters and Custom Parameters

UTM parameters (utm_source, utm_medium, utm_campaign) help you identify traffic sources in analytics tools. Custom parameters (sub_id, click_id, partner_id) carry affiliate-specific data through the conversion flow. Always pass both -- UTMs for analytics, custom parameters for commission calculation.

Coupon Code Tracking

Not all conversions start with a click. Influencer marketing, podcast sponsorships, and offline referrals often use coupon codes instead. The user enters a code at checkout, and the system matches it to the affiliate who owns that code. This is especially common in prop trading and e-commerce verticals.

Smart Links

Smart links are dynamic URLs that route users based on device, location, or other criteria while maintaining tracking parameters. A single link can send mobile users to an app store and desktop users to a website, with the same affiliate getting credit for both paths.

For maximum tracking reliability, implement S2S postbacks as your primary method and use coupon codes as a supplementary method for influencer and offline channels. This covers both click-based and non-click-based conversions.

Key Takeaways

  • S2S postback tracking is the most reliable method -- no browser dependency
  • Always pass both UTM parameters (for analytics) and custom parameters (for commissions)
  • Coupon code tracking covers non-click conversions from influencers and offline channels
  • Smart links handle multi-device attribution with a single URL per affiliate
