# It is absolutely CRITICAL that you use certificate validation to ensure and guarantee that
# 1. you are indeed sending the message to *.hanatrial.ondemand.com and
# 2. that you avoid the possibility of TLS/SSL MITM attacks which would allow a malicious person to capture the OAuth token
# URLLIB3 DOES NOT VERIFY CERTIFICATES BY DEFAULT
# Therefore, install urllib3 and certifi and specify the PoolManager as below to enforce certificate check
