Content ID

This page covers data collection for the Content ID variable. See Content for the corresponding reporting dimension.

The content ID variable uniquely identifies each piece of media content. It is required for all streaming media implementations and is the primary key for the Content reporting dimension. Set it at session start and keep it stable across all sessions for the same asset.

Web SDK

Set name inside mediaCollection.sessionDetails when calling sendEvent:

alloy("sendEvent", {
  xdm: {
    eventType: "media.sessionStart",
    mediaCollection: {
      sessionDetails: {
        name: "video-123",
        friendlyName: "My Video",
        length: 128,
        contentType: "vod",
        playerName: "HTML5 Player",
        channel: "Sports",
        streamType: "video"
      },
      playhead: 0
    }
  }
});

Mobile SDK

Pass the content ID as the mediaId argument to createMediaObject.

iOS (Swift)

let mediaObject = Media.createMediaObjectWith(name: "My Video",
                                                id: "video-123",
                                            length: 128,
                                        streamType: MediaConstants.StreamType.VOD,
                                         mediaType: MediaType.Video)

tracker.trackSessionStart(info: mediaObject, metadata: nil)

Android (Kotlin)

var mediaInfo = Media.createMediaObject("My Video",
                                        "video-123",
                                        128,
                                        MediaConstants.StreamType.VOD,
                                        Media.MediaType.Video)

tracker.trackSessionStart(mediaInfo, null)

Roku (BrightScript)

Set name inside mediaCollection.sessionDetails when calling createMediaSession:

m.aepSdk.createMediaSession({
    "xdm": {
        "eventType": "media.sessionStart",
        "mediaCollection": {
            "sessionDetails": {
                "name": "video-123",
                "friendlyName": "My Video",
                "length": 128,
                "contentType": "vod",
                "playerName": "Roku Player",
                "channel": "Sports",
                "streamType": "video"
            },
            "playhead": 0
        }
    }
})

Media Edge API

Call the sessionStart endpoint with name (the Content ID) inside mediaCollection.sessionDetails:

{
  "events": [{
    "xdm": {
      "eventType": "media.sessionStart",
      "mediaCollection": {
        "sessionDetails": {
          "name": "video-123",
          "length": 128,
          "contentType": "vod",
          "playerName": "HTML5 Player",
          "channel": "Sports"
        },
        "playhead": 0
      }
    }
  }]
}

Media SDK

Pass the content ID as the second argument to ADB.Media.createMediaObject:

var mediaInfo = ADB.Media.createMediaObject(
  "My Video",               // name (friendly name)
  "video-123",              // media ID — Content ID
  128,                      // length (seconds)
  ADB.Media.StreamType.VOD,
  ADB.Media.MediaType.Video
);

tracker.trackSessionStart(mediaInfo, contextData);

Media Collection API

Include media.id in the params object of your sessionStart POST request:

{
  "playerTime": { "playhead": 0, "ts": 1699523820000 },
  "eventType": "sessionStart",
  "params": {
    "media.id": "video-123"
  }
}
