Returns the information about iModel creation process.

This endpoint should be used to check if iModel creation completed.

Forked and cloned iModels

When an iModel is a clone, the clonedFrom response entity property will contain information about the source iModel from which this iModel was created, otherwise it will be null. For more information on iModel cloning please refer to the Clone iModel operation documentation.

When an iModel is a fork, the forkedFrom response entity property will contain information about the main iModel from which this iModel was created, otherwise it will be null. For more information on iModel forking please refer to the Fork iModel operation documentation.

To get the details of the source/main iModel use Get iModel Details operation with id value taken from clonedFrom.iModelId or forkedFrom.iModelId.

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

User must have imodels_webview permission assigned at the iModel level. If iModel Role permissions at the iModel level are configured, then user must additionally have at least imodels_webview permission assigned at the iTwin level. If permissions at the iModel level are not configured, then user must have imodels_webview permission assigned at the iTwin level.

Alternatively the user should be an Organization Administrator for the Organization that owns a given iTwin the iModel belongs to.

For more information please refer to Account Administrator documentation section on Access Control API documentation page.

Rate limits

Create iModel operation state

Indicates the current state of the iModel creation process. 'successful' - iModel creation process completed successfully. 'waitingForFile' - iModel is being created from a Baseline File and the file upload to file storage has not been completed yet. scheduled - iModel creation process is scheduled or in progress. This means that the iModel was created using one of the following methods that require background processing: creating an iModel from Baseline File, cloning an iModel, creating an iModel from template. failed - iModel creation process failed. mainIModelIsMissingFederationGuids - iModel fork creation failed because some elements in the main iModel do not have FederationGuid property set.
