Having Trouble Calling Proofpoint TAP API From ICON HTTP Plugin

Using the HTTP plugin

basic auth creds MUST be principal:secret from where you made new API creds in the TAP dash.

Secret creds MUST be the secret key from principal:secret (seems silly no?)

baseURL MUST be : https://tap-api-v2.proofpoint.com

type MUST be basic auth

SSL = YES

finally your GET call MUST be like this (an example)
