Impressions

Tracking impressions allows you to learn what specific users are not interested in. If the app often shows posts about football, and the user never engages with those posts, we can conclude that we're displaying the wrong content. The code below shows how to track that a user viewed 3 specific activities:

JavaScript
const impression = {
  content_list: [
    {
      foreign_id: "post:42",
      actor: { id: "user:2353540" },
      verb: "share",
      object: { id: "song:34349698" },
    },
  ],
  feed_id: "timeline:tom",
};

client.trackImpression(impression);

Be sure to use the same Foreign Ids as used in your feeds. This allows Stream to understand the content of the activities.
