Calling Trackers

When you call the Decision API, you will retrieve a list of the ad items and/or creative assets such as images and videos according to the API you used. The next step you should take is to call the impression tracker URLand the click tracker URL.

A clients web browser, iOS app, or Android app can easily send impressions and click information to the Moloco Commerce Media system using the imp_tracker and click_tracker URLs. To achieve this, MCM provides the tracker URLs within the response of Decision API.

Performance Reporting

The click_tracker and imp_tracker URLs are pre-generated by Moloco inside the the Decision API response. Do NOT generate these URLs manually.

✏️
Both the imp_tracker and click_tracker URLs can be called using either an HTTP GET method or an HTTP POST method with no body. The impression tracker and click tracker URLs may be called asynchronously.

Impression tracker

We recommend calling the impression tracker URL when 50% of the item image’s pixels are visible or when the top two vertices(corners) of the item’s image are visible.

For example, call the impression tracker URL when the shopper lands on a page with an ad image or video. Call impression tracker URL when the shopper scrolls down the page and a new ad image for video is displayed or when a shopper scrolls through a carousel and a new ad image is displayed.
Call the impression tracking URLs a single time when the image or video is displayed.

Click tracker

Call the click tracker URL from the Decision response when the user clicks the ad.
