Hey @mikeaston, Noticed the same issue on my end as well. After communicating with support, it sounds like the HEC enable/disable functionality has been disabled by default for self-service Splunk Cloud trials, with no direct way to enable via the UI. Meaning, there is no way to utilize HEC endpoints for self-service trials at the moment. The team is working to address the issue, but there is currently no timeline for an update. Cheers, ZQ ...
