## Remarks

- Same rules as [GetSharedLinks](https://developer.m-files.com/APIs/gRPC-API/Reference/MFiles.IRPCSharedLinks/GetSharedLinks/index.md): users with the
  vault right `see_all_objects` get every user's links, other users only their own.

| Field | Type | Description |
|---|---|---|
| `obj_id` | [`ObjID`](https://developer.m-files.com/APIs/gRPC-API/Reference/Messages/MFiles.ObjID/index.md) | The object. |
| `obj_id.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_id.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_id.item_id.internal_id` | `int32` | The ID of the object or value list item. |
| `obj_id.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. |
