A thread 🧵 of _terrible_ design decisions for the internal APIs of the two Italian high speed train operators, Italo and Trenitalia. Hardcoded passwords, terrible translations, spelling mistakes, xml in json (but utf8 encoded and transmitted as an array of numbers), it's all here. Enjoy!

The Italo account area allows you to manage their newsletters. If you try to disable one, it just errors.

FWIW their booking system crashes if you try to change a base ticket and you have a + in the email, so I’m not surprised by anything. Obv you get no error.
