Build a server-to-server postback URL for your tracker or affiliate network. Values are kept as typed, so macros like {clickid} and {payout} are preserved. Test the result with the Postback Tester.

The Postback URL Builder assembles a server-to-server (S2S) postback URL from your tracker’s endpoint and a set of parameters. It pre-fills the parameters affiliate networks use most - clickid, payout, currency and status - with their standard macros, and keeps every value exactly as typed so placeholders like {clickid} survive for the platform to substitute at conversion time.
A postback (server-to-server / S2S) URL is a link your tracker or traffic source calls on the server side when a conversion happens. Because it does not rely on the browser, it is not affected by ad blockers or cookie restrictions, which makes it the most reliable way to pass conversions between platforms.
Macros are placeholders the sending platform replaces with real values when the postback fires - {clickid} becomes the actual click identifier, {payout} the conversion payout, and so on. The builder leaves them untouched so the platform can fill them in.
Use the Postback Tester to send a real test conversion and see the exact HTTP status and response the tracker returns, and the Click ID Generator to create a test click id.
