For example: account==account_id, country=country-code, or viewer=viewer_id (in the last case, the form of the viewer_id will vary depending on whether you are capturing and sending some kind of viewer_id yourself or depending on the value generated by the analytics system). none
limit Number of items to return no positive integer 10
offset Number of items to skip no positive integer 0
sort Field to sort items on no any field that is being returned by the request video_view

format Format to return results in no json (default) | csv | xlsx json
reconciled If included, will limit results to either historical or realtime data. Analytics data is derived from multiple sources: some is sent by the player, but other data is collected from CDNs and the Video Cloud system. In order to deliver analytics as quickly as possible, we start delivering "real-time" data as soon as it is available, and then adjust the analytics later when data from all sources has been collected and processed. The fully processed data is called reconciled no true | false true
from The beginning of the date range for the request no One of the following:
  • An ISO 8601 date (YYYY-MM-DD)
  • Epoch time in milliseconds (example: 1659641316719 [= Thursday, August 4, 2022 7:28:36.719 PM GMT]). See the Epoch time converter.
  • A string: from=alltime
  • +/- relative dates in minutes (m), days (d) or weeks (w) - example: from=-6m&to=%2B2w (the period from 6 minutes ago to 2 weeks after that -- note that the + sign needs to be URI encoded as %2B)

Only dates within the past 32 days are allowed for engagement endpoints or if reconciled=false.

 -30d
to The end of the date range for the request no One of the following:
