## Request: GetIdentitiesAndViewsOfMultipleUnmanagedReducedItemsRequest

> Nested message fields are expanded to depth 3; follow a type link for deeper levels and for the type's own page.

| Field | Type | Description |
|---|---|---|
| `obj_ids[]` | repeated [`ObjID`](https://developer.m-files.com/APIs/gRPC-API/Reference/Messages/MFiles.ObjID/index.md) | Object IDs (managed or unmanaged) (represented by ObjIDArray struct.) |
| `obj_ids[].type` | `int32` | The object type ID, for example 0 for documents. In a lookup value, the value list ID (for a lookup to objects, the object type ID). |
| `obj_ids[].item_id` | [`ItemID`](https://developer.m-files.com/APIs/gRPC-API/Reference/Messages/MFiles.ItemID/index.md) | The ID of the object within its type, in `item_id.internal_id`. |
| `obj_ids[].item_id.internal_id` | `int32` | The ID of the object or value list item. |
| `obj_ids[].item_id.external_repository_id` | [`ExternalRepositoryID`](https://developer.m-files.com/APIs/gRPC-API/Reference/Messages/MFiles.ExternalRepositoryID/index.md) | Used only for objects in external repositories (external connectors). Leave it unset for objects stored in the vault. |
| `allow_missing_object_versions` | `bool` | True if the method is allowed to return less results than requested. This can happen if the user does not have access to all of the objects. |
