Tracking Documentation
This documentation describes how Tracking and Attribution works for both Android and iOS with the JustTrack SDK.
In general, we do a last click/last view attribution. In order to find the best possible match between a click/view and an install, we support the following attribution practices (available both s2s and non-s2s):
    Referrer for Android
    Device id based - GAID for Android and IDFA for iOS (prior to iOS 14)
    Probabilistic fingerprinting in accordance with Apple's guidelines for iOS 14
    SKAdNetwork for iOS 14
    Postbacks from other attribution providers
We use a scoring logic that allows us to determine the most likely click, view or postback that caused an install.
During this process, we value the Playstore referrer, GAID and IDFA as the strongest signals. If they are missing, we do probabilistic fingerprinting and take additional parameters like IP, device type, device resolution and more into account.
Please check the specifications for each platform in the individual subsections for Android and iOS.
The tracking parameters as well as the postback parameters for both iOS and Android can be found on this page. If there is a difference between the platforms or iOS 14, it is highlighted.

View and Click Tracking

In order to track the source of the app installs, we rely on an internal view and click tracking tool. Therefore, we provide custom tracking URLs including required and optional parameters.
Depending on the campaign goal we can trigger postbacks on app installs as well as on custom in app events set up via the JustTrack SDK.
We provide network specific tracking URLs. On app install, we check the referrer as well as additional information to match an app install with the associated view and click events.

Tracking URL Pattern

All tracking URLs match the following pattern:
domain+ event + appBundleId +network specific ID + required tracking parameters + optional tracking parameters
click tracking URL
view tracking URL
Example click tracking URL containing all required parameters and some optional parameters.
https://tracking.justtrack.io/click?appBundleId={appBundleId}&network={networkId}&sourceCampaignId={sourceCampaignId}&platform={platform}&bidValue={bidValue}&clickId={clickId}&sourceId={sourceId}&creativeName={creativeName}&creativeId={creativeId}
Example view tracking URL containing all required parameters and some optional parameters.
https://tracking.justtrack.io/view?appBundleId={appBundleId}&network={networkId}&sourceCampaignId={sourceCampaignId}&platform={platform}&bidValue={bidValue}&viewId={viewId}&sourceId={sourceId}&creativeName={creativeName}&creativeId={creativeId}
    The {networkId} will be provided by us and will be generated automatically in the JustTrack dashboard.
    The remaining placeholders for the required and optional tracking parameters have to be provided by the partner network and configured in the JustTrack dashboard by the advertiser.
    The JustTrack dashboard will generate the network specific tracking links according to the configured placeholders.
