Session start

The session start event opens a media tracking session. It must be the first event sent for any playback. The response returns a session ID that all subsequent events for the same session must include.

Web SDK

Call sendEvent with eventType: "media.sessionStart" and the required sessionDetails. The response includes the session ID in handle[].payload[].sessionId (type media-analytics:new-session). Store this value and pass it as sessionID in all subsequent events.

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

Mobile SDK

Call trackSessionStart with a media object and optional metadata.

iOS (Swift)

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

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

Android (Kotlin)

val mediaObject = Media.createMediaObject("video-123",
                                          "video-id-123",
                                          128,
                                          MediaConstants.StreamType.VOD,
                                          Media.MediaType.Video)

tracker.trackSessionStart(mediaObject, null)

Roku (BrightScript)

Call createMediaSession with the required session details:

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

Media Edge API

Call the sessionStart endpoint. The response includes the session ID in handle[].payload[].sessionId (type media-analytics:new-session).

curl -X POST "https://edge.adobedc.net/ee/va/v1/sessionStart?configId={datastreamID}" \
--header 'Content-Type: application/json' \
--data '{
  "events": [{
    "xdm": {
      "eventType": "media.sessionStart",
      "mediaCollection": {
        "sessionDetails": {
          "name": "video-123",
          "playerName": "HTML5 Player",
          "contentType": "VOD",
          "length": 128,
          "channel": "Sports"
        },
        "playhead": 0
      }
    }
  }]
}'

Media SDK

Call trackSessionStart with a media object created using ADB.Media.createMediaObject:

var mediaObject = ADB.Media.createMediaObject(
  "video-123",                  // name
  "video-id-123",               // media ID
  128,                          // length (seconds)
  ADB.Media.StreamType.VOD,     // stream type
  ADB.Media.MediaType.Video     // media type
);

tracker.trackSessionStart(mediaObject, null);

Media Collection API

Send a sessionStart POST to the sessions endpoint. The response Location header contains the session ID to use in all subsequent event requests.

{
  "playerTime": { "playhead": 0, "ts": 1699523820000 },
  "eventType": "sessionStart",
  "params": {
    "media.channel": "Sports",
    "media.playerName": "HTML5 Player",
    "media.contentType": "vod",
    "media.length": 128,
    "media.id": "video-123"
  }
}
