Create iModel Changeset Group - iModels

REST API Overview

Reference

iModels

Download API definition:

POST https://api.bentley.com/imodels/{id}/changesetgroups

Creates a new Changeset Group.

Changeset Groups are a way to logically group Changesets. Changesets that belong to the same Changeset Group may be interpreted as one logical change to the iModel, for example, iModel synchronization process may create multiple Changesets but they all represent one synchronization run.

The intended workflow is as follows:

Application creates a Changeset Group.
Application pushes one or more Changesets to that Changeset Group by setting groupId property on the Changeset entity.
Application updates Changeset Group and sets its state value to completed.

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.

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