Safeticket Python API script

Udgivet 2016-10-09 - Skrevet af Philip Sørensen

During my time as IT responsible for Student Society at Aalborg University we got a new webshop through Safeticket. This new webshop brought a lot of opportunities, but most importantly, for the first time in a long time it didn't crash at the beginning of the school year when people were buying tickets for the huge party held every year to welcome the new students. 4-5 thousand people attend this party, so it is quite a number of tickets being sold, easpecially during the last few days. For fun I wanted to make a script that played the Mario coin sound each time a ticket was sold, so I made this Python script.

Note that the method for playing the sound may be OS specific. I developed the script to run on Ubuntu using the program mpg321 to play sound. The sound I used can be found here: Mario coin sound.
