I hope I can explain this fully :)
I have a web service URL that accepts a JSON string from a 3rd party application but it is failing with the above error.
Two things to note:
1. if I configure the 3rd party app to send to a public testing URL (http://requestb.in
) it seems to work just fine
2. If I copy the raw body and test it directly on my server, it also works perfectly and return a 200 response
However, when I configure the 3rd party app to send to my URL my service returns 500 response. I have added the application/json mime type to IIS.
I'm sure the issue is on my end but I'm at a loss as to how to troubleshoot this further
The attached image shows the test screen and the resulting 200 response
Any help would be greatly appreciated
