Para qu茅 ?
Desde el c贸digo de su aplicaci贸n, puede iniciar sesi贸n en cualquier portal web. Esto puede ser necesario cuando desee acceder a los recursos de su cuenta.
驴Qu茅 puedes conseguir en este portal?
Puede obtener una lista de sus viajes, o puede verificar qu茅 viajes est谩n planificados en todo el portal desde el punto "A" hasta el punto "B" para una fecha espec铆fica. Puedes hacer m谩s.
