This endpoint is used to create a configuration for a PopulateFederationGuids transformation.

Populate Federation Guids transformation creates a new FederationGuid property value on elements that currently have FederationGuid value set to null.

This transformation is useful in iModel Forking scenarios when iModel fork creation in iModels API fails with sourceIsMissingFederationGuids state. After Populate Federation Guids transformation is run on the source iModel subsequent "Fork iModel" operations will succeed.

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 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.

Important: Populate Federation Guids transformation is in closed preview mode currently and only selected applications can utilize it.

Rate limits

---

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