Changed Elements API

The Changed Elements API provides consumers with the elements that have changed in an iModel between two changesets. This API has two operations:

  1. Enable Change Tracking
  2. Get Comparison

Before obtaining a comparison, it is necessary to enable change tracking of an iModel. This means that the API will be listening to any new Named Versions that are created on the iModel. When that happens, the API will process the new changes and store a summary of all the elements that have changed.

After tracking is enabled and the iModel is processed, the comparison endpoint may be used to query for a summary of changed elements between any two given ChangeSets.
