We are using the /api/v2/analytics/conversations/details endpoint in our ETL code and loading into an Oracle staging view. The tWait values are always 0. I found another thread on the same topic, but I don't entirely understand the recommendation:
"If you want to get the wait time of each conversation, use a detail query and calculate the time in queue based on the ACD participant. For the detail query, you'll want to use a segment filter for segmentEnd not exists, purpose is acd, and the queue id."
In this example, is the tWait = 9 seconds?
