Indeed conversion tracker code.

Indeed sent me a script along with this email:

find the conversion tracker code. This small piece of code needs to be placed on the page that displays after a candidate submits a completed application (like the Thank You page). Once this page displays, the code will send our system back a message letting us know that a conversion has occurred. Conversion Tracker will only track sponsored clicks from Indeed that turn into completed applications. This way you will be able to measure exactly how many applicants you have received from Indeed.

Where should I put this script code they sent over?
