A project represents a distinct application offered by a vendor. A vendor that only offers a single application, such as spreadsheets, would only need one project, while a vendor offering spreadsheets and calendars would have two projects. You can find your project IDs on the Settings page of the admin site.
An environment represents a deployment target for a project. Retraced generates Production and Staging environments for each new project. You can manage your project’s environments with the Admin API or the admin site.
A group is an end customer in your multi-tenant application. You can segment your audit log into groups by adding a
group.id to each event. Then you may provide your end customers read access to their segment with the Enterprise API.
