Download API definition:
GET https://dev-api.bentley.com/itwins/{iTwinId}/repositories[?class][&subClass]

Gets the details of the specified repository.

A repository is a Uri link to iTwin data managed by another service.

For example, if an iTwin has Forms data then you can get the Uri for that data by using this api and specifying iTwinId = 547d397a-9921-4e4f-a7a2-c47fc19219b0 and Class = Forms. It will return the following.

{
   "repositories": [
   {
      "id": "547d397a-9921-4e4f-a7a2-c47fc19219b0",
      "class": "Forms",
      "subClass": null,
      "uri": "https://api.bentley.com/forms?projectId=547d397a-9921-4e4f-a7a2-c47fc19219b0"
   }]
}

If no Class is specified then all repositories containing data for the iTwin will be returned. The Uri is automatically generated by calling each service to determine if its repository contains data for the specified iTwin. For example, if there are no iModels for the specified iTwin then the iModel Repository Uri will not be returned.

The following Classes/SubClasses are supported. Classes in italics are auto generated. The others can be added manually using the POST endpoint.

  • iModels
  • RealityData
  • Storage
  • Forms
  • Issues
  • SensorData
  • GeographicInformationSystem
    • WebMapService
    • WebMapTileService

  • Construction
    • Performance
