Since there are two different server side pixel methods, we'll explain when to use each. Server side pixels are called 'Click ID Pixel Post or Postback' or 'AFID Pixel Post or Postback'. These pixel posts can occur within the code of the confirmation page (Client side) or from a back office server (Server side).
The Click ID Pixel Post is the most secure form of creating a transaction from a server side pixel because it requires a valid click ID which can only be generated by LinkTrust when a consumer clicks through a tracking link. This feature is enabled by default within the campaign settings.
