Audience Retention Data of Youtube Video via API

Question

Is there a way to retrieve the audience retention data of any Youtube video via API (preferably using Python)?

I found the same question asked 9 years ago, but they were told that the feature didn't exist yet – does it exist now?

Answer 1

There is a YouTube Analytics (V2) API that allows users to fetch audience retention data of a single YouTube Video.

You set the dimension to elapsedVideoTimeRatio, and use relativeRetentionPerformance for metrics and include video=={yourVideoID} for filters!

This will output a result in the following format: \

{
"kind": "youtubeAnalytics#resultTable",
"columnHeaders": [
{
  "name": "elapsedVideoTimeRatio",
  "columnType": "DIMENSION",
  "dataType": "FLOAT"
},
{
  "name": "relativeRetentionPerformance",
  "columnType": "METRIC",
  "dataType": "FLOAT"
}
],
"rows": [
