 * `ignoreUserWindow`: Used with `ignoreUserCount` indicating the number of minutes that `ignoreUserCount` affected users will be ignored 
 * `ignoreDuration`: The duration (in minutes) that an archived issue should be ignored before it gets escalated. Increase in the number of users affected or the number of occurrences will not escalate before this duration has passed unless there is a spike. To learn more about how this works, see [Escalating Issues Algorithm](/product/issues/states-triage/escalating-issues/).
 
+### issueCategory & issueType
+`issueCategory` and `issueType` provide more detail to distinguish different issues from eachother. For `issueCategory` variations include, `outage` (for issues created from `uptime` and `cron` monitors) and `error` (for issues created from an error event).  
+
+`issueType` allows for even more specificity on top of `issueCategory`, examples include `uptime_domain_failure` for `uptime` issues and `monitor_check_in_failure` for `cron` issues.
+
+The issue categories we currently support `issue.created` webhooks for are `OUTAGE`, `ERROR`, and FEEDBACK.
