Conversion Parameters

Example Use Case: Passing Sale Amount
Many e-commerce advertisers use cost-per-sale (CPS) models where the conversion payout is based on a percentage of the sale. To track this, the advertiser must include the cnv_amount parameter in the postback:
https://gokart.api/track?gk_click_id={sub1}&cnv_amount={advertiser_amount_macro}
{advertiser_amount_macro} will be dynamically replaced with the actual sale amount by the advertiser’s system.
This allows GoKart to report and calculate earnings based on the conversion value.
