What does the "No Hacking, 999" error mean when using Pressero V6 API?

PRESSERO > *Integration Information & Supported Services
One of the main reasons for this error is that the API call that is being done, is being blocked by our Application Firewall. Please submit a support ticket here if you are receiving this error and we will analyze it.
When using a python request with a "User-Agent", Pressero does not support it.
To avoid this type of error, please remove the "User-Agent" or use a "User-Agent=None", and your request will work.
