Looks like you need to set the Content-type header on the request?
restRequest.contentType = "application/json";
We are using Postman right now for my REST API calls.
the header looks like this:
Content-Type : application/json
Accept : application/json
everything looks fine, but the issue is very unclear...
There should be some error messages in the catalina log file on the VA (/var/log/vcac/catalina.out)
If it's a serialization issue (according to the server) then double check the JSON body content (jsonviewer.stack.hu) and then double check all HTTP headers. At that stage it might be an SR if the server still refuses the content
Was there a solution to this? I am looking to do the same thing in our environment
