Sold Postback URL

Postback represents the URL provided by publishers where information about every visit sold by Zeropark is sent. Publishers may track this kind of data outside of the Zeropark platform and need to be informed when a sold visit occurs. Postbacks are sometimes also called callbacks, server-to-server (s2s), or cookie-less conversion tracking. They are one of two methods of reporting conversions, the other being the conversion or tracking pixel.

Postbacks allow servers to communicate with each other directly. A client is not involved, no cookies are used on a visitor’s computer. Once activated by a source platform, these links send information to the target platform (a tracker or traffic source) in the blink of an eye.

Instructions for publishers:

You must provide the Zeropark Account Manager with the URL address to which you want to send information about the sold visit immediately after it is sold. It is important that you first include the clickID parameter (HTTP request parameter name: extclickid) in your requests, which we will then use when sending a postback for that specific visit. This parameter will allow you to match the incoming postback to the visit sent to us.

The parameters we can provide are:

• {payout} – format: number, example: 0.00003
• {extclickid}– format: string, example: dmr0lnr3c0. We must first receive this parameter in the request to be able to send it back
• {visitid}– format: UUID, example: a248cdf4-21f7-4e3d-b566-add8ee8c2534.Its value is equal to the "id" sent in the bid response on zeroclick
• {visittimestamp} – format: ISO 8601, format pattern: yyyy-MM-ddThh:mm.sssZ, example: 2017-03-22T13:02:32.023Z
• {advertiserId} - format: UUID, example: 0eb4b794-a400-4933-b432-751200f36a18
