GoKart supports enhanced postback functionality so advertisers can pass additional data with each conversion. These optional parameters can be appended to your postback URL to provide any additional conversion insights. The values of these parameters come from the advertiser.
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:

{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.
