Custom Properties

Apart from the pre-set values that Trackerbird collects, such as OS version, product version, edition, language, license type, etc. you also have the possibility to collect any custom value that is relevant to your specific application.

Typical examples where you can benefit from custom properties include storing the download source or marketing campaign from where the user downloaded your software or else some other status in your application. These custom properties will then be available inside the filters panel on every report so you may use them as part of your report filtering criteria.

Please note that Custom properties are intended to store values that are not very dynamic for a particular installation since the reporting granularity provided by Trackerbird is on a daily basis. This means if you use this API to register multiple values inside the same custom property (for the same user), Trackerbird will only store the latest known property value for that user on that particular day.

Note: By default you can store up to 1000 unique values inside every custom property. Please contact Trackerbird support if you want to discuss this limit or alternative uses.
