Create a Named Version.

Every Changeset on the timeline creates a new version of the iModel. However, some points on the timeline can represent important milestones or significant events to be saved. iModelHub provides a way to mark a point on the timeline with a name. These time points are referred to as Named Versions.

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_write 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_write 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.

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 please visit our 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.
