    iTwins
    Download API definition:
    Create export
    POST https://api.bentley.com/itwins/exports

    This api will create an export job with the given parameters.

    When you create a new export job, it is added to a queue. The service will only process two export jobs at a time. Most exports will only take a few seconds to complete. It may take several minutes if the export is very large (more than 100,000 itwins) or if there are many exports in the queue.

    The output file will be saved to a storage account and automatically deleted after 4 hours. The url of the file will be returned when you query for the details of the export using the Get Export or Get My Exports APIs.

    Quotas

    A user can only have one Queued or InProgress export job at a time.
    A user can only create 3 export jobs per hour.

    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

    Any user can create an export job. Only an Organization Administrator can create an export job that uses the OrganizationAdmin query scope.

    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.

    Request body

    iTwinExportRequest

    Name
    Type
    Required?
    Description
    queryScope
    QueryScope
    No

    MemberOfiTwin - (Default) The export will be limited to the iTwins that the user is a member of. Use the Access Control API to manage an iTwin's members.
    OrganizationAdmin - The export will be limited to the iTwins that belong to the users organization. It can only be used by an organization admin. It is useful for admins that want to export all iTwins in their organization.

    subClass
    String
    No

    One or more iTwin subClasses. Use a comma delimited list to specify more than one. For example, to export Assets and Projects, specify 'Asset,Project'. If not specified, the export will include all subClasses.

    select
    String
    No

    A comma delimited list of iTwin properties that you want to include in the export. Keep the list of properties as small as possible to increase the speed of the export and limit the size of the export file. If not specified, then it will export the minimal representation which includes these columns: id,class,subClass,type,number,displayName

    filter
    String
    No

    An odata filter used to limit the iTwins that are exported. Use the subClass property to limit to specific subClasses. The filter is used to filter the results even further. All text values in the filter are case insensitive.
    Examples:

    • status+in+['Active','Inactive']
    • status+eq+'Active'+and+contains('test',number)+and+CreatedDateTime+ge+2023-01-01T00:00:00Z
    • parentId+eq+'78202ffd-272b-4207-a7ad-7d2b1af5dafc'+and+(startswith('ABC',number)+or+startswith('ABC',displayName))
    includeInactive
    Boolean
    No

    By default, Inactive iTwins are not returned from any API. This flag allows you to indicate that you want the export to include inactive iTwins. If not specified, the export will include iTwins with any status but Inactive, including any new status added in the future. If you specify a status in the filter parameter, then an error will be returned if you also try to set the includeInactive flag.

    outputFormat
    ExportOutputFormat
    Yes

    JsonGZip - A single large json file compressed using gzip. (filename.json.gz)
    JsonZipArchive - A zip archive containing multiple json files. Each file contains 20,000 itwins. (filename.zip)

    Csv - A single uncompressed csv file. (filename.csv)
