This endpoint is used to create a configuration for filtering out geometry entries based on their sub-category names.

A SubCategory is a subdivision of a Category. SubCategories allow elements in iModel to have multiple pieces of geometry that can be independently visible and styled (color, linesStyle, transparency, etc.). For more information, see SubCategories.

FilterSubCategories transformation is filtering out all of the data associated to subCategoryNames specified for the transformation.

Configuration specific properties explained:

subCategoryNames - array of sub category names.

In addition to exported data, the transformer will also push some additional metadata. This metadata contains:

1. BisCore:RepositoryLink and BisCore:ExternalSource elements that mark the source where the data was imported from.
2. A "Scope" BisCore:ExternalSourceAspect that contains Synchronization changeset metadata that is needed by the transformation service to process any later changes correctly.
3. Element provenance information (BisCore:ExternalSourceAspects) for elements that do not have federation guids.

Note: Creating a configuration does not run the transformation. To run the transformation, please see transformations reference.

Authentication

---

Requires Authorization header with valid Bearer token for scope itwin-platform.

For more documentation on authorization and how to get access token visit OAUTH2 Authorization page.

Authorization

---

You must have imodels_write assigned at the target project level and imodels_read assigned at the source project level within related configuration. If permissions at the project level are not configured, then you must have same assigned at the iModel level.

Alternatively, you must be an Organization Administrator for the Organization that owns a given project the iModel belongs to.

An Organization Administrator must have at least one of the following roles assigned in User Management: Account Administrator, Co-Administrator, or CONNECT Services Administrator. For more information about User Management see Bentley Communities Licensing, Cloud, and Web Services wiki page.

Rate limits

---

All iTwin Platform API operations have a rate limit. For more documentation on that visit Rate limits and quotas page.
