After deploying and configuring the Mainframe Webhook Server into a tomcat server dedicated to the Endevor Webservices, the webhook end-point is not received any notifications of the mainframe events. When looking at the mainframe Webhook Server logs, there's only some debug messages, but nothing concerning the pkglog directory it should be monitoring. There's no evidence of a failure in the logs, it seems it's just not picking up the triggers.
Check version in Mainframe Webhook Server UI, bottom section. If no version displayed, it is 2.0 or lower
Contact CA support and get Mainframe Webhook Server 2.2
