the source for the js seems to be at: https://www.hackthebox.eu/js/inviteapi.min.js

then go to https://gchq.github.io/CyberChef/ which is one of the best debugging platform.

Copy your base64 code and paste it in the website selecting the From base64 option

put you base64 in input and get the output as in the figure

now, use curl in the terminal to go the site /api/invite/generate with POST method as shown in the figure,

sending the request, you will get your code,

now copy the code and decrypt the value again using the same process like we did before and you will get,(its in BASE64)

Copy the code in the output and place it in the invite,

use the invite code in the box that was prompted at the beginning,
