The Source for applications is automatically recorded if you use the built in advert uploader that comes with Perform Zone. The uploader inserts an advert code, called tadv code for each of the source’s application URL. This URL is provided to applicants to allow them to get to your application page. This code is then read by the Perform Zone application page and the relevant source is recorded with the application.
