Retrieves the metadata of a Changeset.
For more information on creating and retrieving Changesets using iTwin.js see working with Changesets.
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.
Note: download
property requires user to have at least imodels_read
permission. If user has only imodels_webview
permission download
will always be null.
Rate limits
All iTwin Platform API operations have a rate limit. For more documentation on that visit Rate limits and quotas page.

iModel id
Changeset id or index
Request headers
OAuth access token with itwin-platform
scope
Setting to application/vnd.bentley.itwin-platform.v2+json

Changeset
Changeset represents a file containing changes to the iModel. A single Changeset contains changes made on a single Briefcase file and pushed as a single file.
Id of the Changeset.
Display name of the Changeset. Corresponds to Index property.
Description of the Changeset.
Index of the Changeset (increasing, but not necessarily sequential).
Id of the parent Changeset.
Id of the user who created the Changeset.
Date when the Changeset was pushed to iModelHub.
Id of the briefcase that was used to push the Changeset.
Size of the Changeset file in bytes.
Describes what type of changes Changeset contains. Tells what changes changeset contains. 0 - regular, 1 - schema, 2 - definition, 4 - spatial data, 8 - sheets and drawings, 16 - views and models, 32 - global properties. ContainingChanges is flag value, therefore all change types, except Schema, can be combined.
Indicates the state of the Changeset. 'waitingForFile' - indicates that Changeset metadata is created, but Changeset file is not uploaded yet or file upload is not confirmed yet. 'fileUploaded' - indicates that Changeset file is uploaded and confirmed.
Optional information about synchronization that is related to the Changeset.
