Wozu ?
Über den Code Ihrer Anwendung können Sie sich bei jedem Webportal anmelden. Dies kann erforderlich sein, wenn Sie auf die Ressourcen Ihres Kontos zugreifen möchten.
Was können Sie auf diesem Portal bekommen?
Sie können eine Liste Ihrer Reisen abrufen oder überprüfen, welche Reisen für ein bestimmtes Datum auf dem gesamten Portal von Punkt "A" bis Punkt "B" geplant sind. Sie können mehr tun.
Was brauchst du?
