S2S Postback Tracking: Stop Losing Conversions, Darling

[Big Betty Partners]

Your dashboard may look polished, darling. But if registrations, FTDs, and deposits disappear somewhere between the click and the report, that fine-looking setup is all show and no go.​

S2S postback remains one of the most reliable ways to track iGaming conversions because data travels directly between servers. Unlike browser pixels, postbacks are not disrupted by ad blockers, deleted cookies, Safari ITP, incomplete page loads, or iOS privacy restrictions.

Research referenced by WeCanTrack and Voluum suggests that pixel-only tracking can create attribution gaps of up to 17.5%. For affiliates spreading traffic across several programs, that gap can distort campaign reports, ROI calculations, and commission data mighty fast.

How S2S Tracking Works​

The process follows a simple attribution loop:

1. A user clicks an ad.
2. The tracker generates a unique click ID.
3. The click ID passes through the affiliate link.
4. The user registers or completes another conversion event.
5. The affiliate platform sends the click ID and conversion data back to the tracker.

That click ID connects the conversion with the original traffic source. A typical postback may also contain:

• payout value
• conversion type
• transaction ID
• event status
• currency

For iGaming campaigns, trackers can record registrations, FTDs, recurring deposits, NGR, and custom events. That matters because the conversion journey rarely ends with a single browser session.

Keitaro, Binom, or Voluum?​

All three trackers support S2S tracking, yet their workflows differ.

Keitaro is self-hosted and gives affiliates full control over infrastructure and data. It offers more than 500 templates for traffic sources and affiliate platforms, making it a strong fit for projects that require flexible integrations.

Binom is also self-hosted and focuses heavily on speed. Its click-processing benchmark is around 7 milliseconds, which may appeal to affiliates handling high PPC volumes and frequent traffic spikes.

Voluum uses a cloud-based setup. Affiliates do not need to maintain their own server infrastructure, and reporting across multiple campaigns or affiliate programs can be managed in a single environment. Its direct API integrations can also reduce the need for manual postback configuration.

The practical choice depends on your priorities:

• Keitaro for control and extensive template coverage
• Binom for speed and straightforward deployment
• Voluum for centralized cloud reporting and automation

No tracker wins every category, tiger. The right one is the platform that fits your traffic volume, technical resources, and reporting workflow.

Tracking with Affilka​

Affilka supports native S2S postbacks for events such as:

• registration
• FTD
• any deposit
• prequalification
• disqualification
• NGR

Affiliates can map click IDs, deposit amounts, revenue values, and transaction IDs directly to their tracker. Big Betty Partners uses Affilka-based tracking and supports connections with Keitaro, Binom, and Voluum.

Before launching traffic, always run a manual postback test. Confirm that the tracker receives the correct click ID, conversion type, payout, and status. One small test can prevent a mighty expensive reporting problem later.

Betty’s Verdict​

Accurate tracking is not an optional technical detail. It determines which campaigns you scale, which traffic sources you pause, and whether reported commissions reflect actual player activity.

Pixels still have their place, but server-side tracking provides affiliates with a more reliable view of registrations, FTDs, deposits, and revenue events. When several programs and traffic sources are involved, clean attribution becomes the difference between smart optimization and expensive guesswork.

Keep your tracking sharp, darling. Missing conversions do not belong in a boss campaign.

I just started using postbacks, but noticed that a lot of programs do not have this. In fact, out of the affiliate software (of the programs I promote), I have only found Affilka using postbacks

What other software makes use of postbacks?

Yes, Affilka is one of the platforms that supports native S2S postbacks. Others include Income Access, NetRefer, Cellxpert and Scaleo, all of which offer server-to-server/postback tracking capabilities.

Big Betty uses Affilka, with S2S tracking for registration, FTD, deposits, NGR and other events. It can also be connected to trackers such as Keitaro, Binom and Voluum.

For those tracking deposits after the FTD: do you send each deposit as a separate event, or update the original conversion? Curious how people keep that clean in Keitaro or Voluum when player activity continues.
