Reality Management

Download API definition:

GET https://dev-api.bentley.com/reality-management/reality-data/[?iTwinId][&continuationToken][&$top][&extent][&$orderBy][&$search][&types][&acquisitionDateTime][&createdDateTime][&modifiedDateTime][&lastAccessedDateTime][&ownerId][&dataCenter][&tag]

Retrieves a list of reality data instances belonging to the specified iTwin.

The retrieved instances are those for which you have the required access rights, relative to the specified iTwin.

The iTwinId is optional. If you don't provide it, the retrieved reality data instances will be relative to general access rights provided by your organization. These rights are usually more restrictive, so we recommend using the iTwinId parameter for exhaustive results.

Notes

The Prefer header can be used to specify how much result metadata is desired by the client. The Prefer request header field is used to indicate that particular server behaviors are preferred by the client but are not required for successful completion of the request.

This operation supports "return=representation" and "return=minimal" preferences.

The "return=representation" preference indicates that the client prefers that the server include an entity representing the current state of the resource in the response to a successful request, i.e., all properties are included in the response. The "return=minimal" preference indicates that the client wishes the server to return only a minimal response to a successful request. This is the default preference if Prefer header is not specified.

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 be an Organization Administrator for the Organization that owns a given iTwin or must have access to context.
