Enable this option if you would like to trigger new builds by accessing a special predefined URL (convenient for scripts).

One typical example for this feature would be to trigger new build from the source control system's hook script, when somebody has just committed a change into the repository, or from a script that parses your source control email notifications.

You'll need to provide an authorization token in the form of a string so that only those who know it would be able to remotely trigger this project's builds.
