Is they any way to capture a full Splunk HEC payload coming into the Splunk HEC source before it breaks out the event into _raw? I have a source sending into /services/collector/event so I know event in the JSON is what gets stored as _raw. I would like to see the rest of the JSON outside of the event field when the data is sent. It is a cloud based source so I cannot check on that end. Is this possible?

Not with the HEC source. You could either temporarily set-up a raw TCP input and capture the payload, or use something like nc on the CLI to capture
