A conversion postback is, structurally, a message from someone else's server telling your network what to pay out. If your payout logic trusts that number directly, you've handed pricing control to whichever party benefits from inflating it.
Fatexia's tracker treats a postback as a single fact: a conversion happened, at this time, for this click ID. Nothing more. The amount owed is always looked up fresh from the offer's own payout rule at the moment the conversion is processed — the same rule an affiliate can see before they ever send traffic.
This isn't a subtle implementation detail. It's the difference between a payout you can reproduce from public information and one you have to take on faith. When a rule changes, it changes going forward — it doesn't retroactively rewrite what a past conversion was worth, and it never depends on a number typed into someone else's system.
The practical effect: fewer disputes, because there's less to dispute. The math is always the same math, computed the same way, from a rule both sides can point to.
