GoKart supports enhanced postback functionality, allowing advertisers to pass additional data along with the required gk_click_id for each conversion.
These optional parameters can be appended to your postback URL to provide extra conversion insights.
The values of these parameters are provided by the advertiser.
Parameter | Description | Example Value |
cnv_amount | The transaction value associated with the conversion event (e.g., sale amount). | 9.99 |
cnv_conversion_id | Advertiser’s conversion ID | ABC123XYZ |
cnv_event_id | Event ID from the tracking system | EVT-7890 |
cnv_conversion_ip_address | IP address of the conversion | 192.168.1.1 |
cnv_email | User’s email associated with the conversion | |
cnv_user_id | Advertiser’s user ID for the conversion | user_5678 |
cnv_sub_1 - cnv_sub_5 | Custom sub-fields for passing additional data | custom_value_1 |
Example Use Case:
Passing Sale Amount
For conversions that involve a purchase, the advertiser can return the purchase amount using the cnv_amount parameter in the postback URL.
Example:
https://gokart.api/track?gk_click_id={sub1}&cnv_event_id=purchase&cnv_amount=AMOUNT_MACROAMOUNT_MACROshould be replaced with the corresponding macro from the advertiser's tracking system.Upon conversion, this value will be dynamically populated with the actual purchase amount.
Including this parameter allows GoKart to accurately record the conversion value, calculate earnings, and generate precise reporting metrics.
