What for ?
From the code of your application, you can log in to any web portal. This may be needed when you want to access the resources of your account.
What can you get on this portal?
You can get a list of your trips, or you can check what trips are planned on the entire portal from point "A" to point "B" for a specific date. You can do more.
What do you need?
