Paging

Page size refers to total size of returned objectIds throughout all returned instances. If several Lock instances are returned that does not necessarily mean that instance is complete and more objectIds might be returned for that specific instance in a different page.

Authentication

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.
