you can enable inbound logging.

How to capture the Inbound REST logs and the associated REST Request Body in the Service Now system ... 

If my response helped please mark it correct and close the thread so that it benefits future readers.

Hi @Ankur,

Thanks for your quick response. I already followed these steps but I cannot find the answer. 

Step 7 gives me an error "Unable to open log file localhost_log"

Step 8 - when I opened the file, its content are only garbled characters.

Also, I read somewhere before that enabling "glide.rest.debug" may involved performance issue. Is this true?

@Paolo2 

that's correct.

what type of API endpoint it is? Is it scripted API? or Import set table API?

No, they simply invoke the /api/now/table/incident API and pass parameters to create an Incident ticket in our Instance. They claim that they provided values for Field X and Y but when we check the ticket created, it is blank. We were hoping there is some kind of evidence or logs we can show to them to prove this case.

Hi, have you got new information how to retrieve the logs, please? I'm struggling with same issue like you. Thanks
