问题
I am sending events from Winform application to Universal Analytics via Measurement protocol and I use fiddler to inspect the request and response. Everything seems to be OK, but no events appears in Universal Analytics.
My app request:
POST http://www.google-analytics.com/collect HTTP/1.1
Host: www.google-analytics.com
Content-Length: 112
Expect: 100-continue
v=1
&tid=UA-44974825-1
&cid=1aba0888-732f-4690-9a91-d906c94a4a23
&t=exception
&exd=NullReferenceException
&exf=1
Server response:

Your request is missing the app name parameter, &an, which is required for sending data to app profiles in Google Analytics via the Measurement Protocol.
The requirements for sending app data to Google Analytics via the Measurement Protocol are documented here: https://developers.google.com/analytics/devguides/collection/protocol/v1/devguide#apptracking
The GA endpoint will always return 200, even if the request is missing required parameters.

I discovered another reason why no data is being collected: I hadn't upgraded my property to Universal Analytics, yet! Doh!

The root problem here is that you are not formatting your request properly. You need to format your POST body like any other application/x-www-form-urlencoded encoded POST body, all on one line:
v=1&tid=UA-44974825-1&cid=1aba0888-732f-4690-9a91-d906c94a4a23&t=exception&exd=NullReferenceException&exf=1

For anyone who lands here looking for solution to something similar, check this tool: Hit builder to validate the payload data. I was facing the same issue this tool helped.
(Not sure if this debug tool was available then when this question was posted)
