Retrieve read access to reality data container

GET https://qa-api.bentley.com/reality-management/reality-data/{id}/readaccess[?iTwinId]

Retrieves the container's link with read access for an instance of reality data.

A container is where the reality data itself (a point cloud, a mesh, a collection of images, …) is stored.

The container's link will allow you to upload/download data directly to this container.

A reality data is always associated to exactly one container.

The iTwinId parameter is optional, but it is preferable to provide it, because the permissions used to access the container are determined from the iTwin. With no iTwin specified, the operation can succeed in some cases (e.g. the user is the reality data's owner), but we recommend to provide a iTwinId.

In future API versions, containers could be hosted in in different cloud providers, but for now, only Azure cloud is supported.

To store or retrieve data from a container, refer to the Azure Blob Storage documentation.

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 have realitydata_use permission for read access assigned at the iTwin level.

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.
