Looking for the list of actions to add to config.json. Here is the list available on integration's config page (I was able to guess "Create"):
OEC action - config.json action
alert is created - Create
alert is acknowledged
alert is unacknowledged
alert is snoozed
a user executes "Escalate to Next"
a note is added to the alert
a responder is added to the alert
a tag is added to the alert
a tag is removed from the alert
alert is closed
alert is escalated
a custom action is executed on alert
a user executes "Assign Ownership"
a user takes ownership of the alert
alert's priority is updated
