Mick Hilhorst 's Tech Blog

Hello Awesome Person,

I hope you enjoyed watching the session “Automating your way to greatness with the ADC Nitro API”. This page will serve the purpose of hosting the video later on and providing the scripts created with commented code.
Please do get started on trying awesome stuff, and always feel free to hit me up on any socials if you need help or want to chat.

Thank you very much for watching.

The code we produced during the session with commenting:

#Import nitro_server for login
