The Nielsen server-to-server solution requires audit pings for the purpose of validating audience reach and video viewing duration; one start and one end for each video stream. Pings originate from the end-user device to Nielsen Collections servers. End pings execute upon cessation of playback.
==Ping Structure==
Ping is executed with following convention:

<code>https://'''[to_be_provided]'''.imrworldwide.com/cgi-bin/gn?prd=audit&+'''[query parameters]'''</code>

The Start Audit Ping carries all parameters in the table below. The End Audit Ping carries a subset of the parameters in the matrix below as denoted in the mandatory column.

Under normal operating circumstances, the audit ping server returns the following codes:
*Audit ping servers reject cross-origin HTTP requests with preflight. To ensure that audit ping requests are accepted, allowable Content-Types like "text/plain" in simple GET requests ensure that preflight requests are not invoked
*200: Ping successfully received, inspect traffic to ensure no CORS errors
=Session & Stream=
#Sessions
##Optionally, a new Session ID may be created when a new player is created
##If more than one video player exists within the same App (e.g. picture in picture) a different Session ID is required for each
#Streams
##New Stream ID is generated for each new video stream.
##If stream playback continues after 24 hours, then a new Stream ID should be created and a new Audit ping should be executed (Session ID may remain)
##Stream ID remains the same independent of fast-forward, rewind, pause, events assuming the asset remains the same
##If playback is suspended for greater than 30mins (paused or otherwise suspended), a new Stream ID should be assigned upon return
##Audit pings should be fired at the beginning and end of a stream
