Google Analytics Measurement Protocol with Remote Post

Has anyone here successfully used Google Analytics Measurement Protocol with Remote Post handler?

I cant even edit "Custom Data" section either. So is this still in development?

If we can edit it, then we should be able to do this...

From the above link:

To send user interaction data, make an HTTP POST request to this endpoint.

POST /collect HTTP/1.1
Host: www.google-analytics.com

payload_data
The following parameters are required for each payload:

v=1 // Version.
&tid=UA-XXXXX-Y // Tracking ID / Property ID.
&cid=555 // Anonymous Client ID.
&t= // Hit Type.
Each payload must contain a valid hit type and each hit type has its own set of required fields. So to send a pageview for the /home page, you would use the following payload:

v=1&tid=UA-XXXXX-Y&cid=555&t=pageview&dp=%2Fhome

Any advice will be great.

Thanks
