Why would a Rest API receiver drop an event?

Getting Data In

We have a double feed from a FireEye device going into Splunk. The idea is to convert from XML over syslog to JSON over port 8089. A comparison done yesterday found an event that Splunk received as XML but it never received the JSON version. Are there any logs that capture events on port 8089? I'm trying to see if there was an error message generated. I had the device owner manually send the event today and Splunk received it without issue. I need to make certain that Splunk receives all JSON events over port 8089 or generates an error when we make the final cutover.

TIA
Joe
