Badges: `Vault API / core` `write` `session or assertion` `returns metadata structure version`

Permanently destroys an object, or one version of it.

- **Service:** [Objects, versions, properties and files](https://developer.m-files.com/APIs/gRPC-API/Reference/MFiles.IRPCObjectOperations/index.md) `MFiles.IRPCObjectOperations`
- **gRPC method:** `/MFiles.IRPCObjectOperations/DestroyObject`
- **HTTP (mf-http-grpc):** `POST /grpc/v1/destroy-object`
- **Request:** [`DestroyObjectRequest`](https://developer.m-files.com/APIs/gRPC-API/Reference/MFiles.IRPCObjectOperations/DestroyObject/index.md#request)
- **Response:** [`DestroyObjectResponse`](https://developer.m-files.com/APIs/gRPC-API/Reference/MFiles.IRPCObjectOperations/DestroyObject/index.md#response)
- **Book and level:** Vault API, core
- **Kind:** write
- **Session:** Required: a session (mfiles-session-id-bin metadata) or a session assertion (x-mf-session-assertion metadata).
- **Idempotent:** no
- **Returns metadata structure version:** yes (in the mfiles-metadata-version-bin trailer)
- **Streaming:** none (unary)

## Remarks

Destroying cannot be undone. Requires the vault-level right to destroy objects (`destroy_objects`):
a normal user gets "Access denied." The object does not need to be deleted first.

* Whole object: `all_versions: true` and `version.type: OBJ_VER_VERSION_TYPE_ALL`. Leaving
  `version` unset fails with "The parameter is incorrect."
* One version: `all_versions: false` and `version` with `OBJ_VER_VERSION_TYPE_SPECIFIC` and the
  number. The latest checked-in version cannot be destroyed: "Destroying the latest checked-in
  version of an object is not allowed."

| 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. |
| `all_versions` | `bool` | True to destroy the whole object; false to destroy the version in `version`. |
| `version` | [`ObjVerVersion`](https://developer.m-files.com/APIs/gRPC-API/Reference/Messages/MFiles.ObjVerVersion/index.md) | `OBJ_VER_VERSION_TYPE_ALL` when `all_versions` is true; otherwise the version number to destroy with `OBJ_VER_VERSION_TYPE_SPECIFIC`. |
| `version.type` | [`ObjVerVersionType`](https://developer.m-files.com/APIs/gRPC-API/Reference/Enums/MFiles.ObjVerVersionType/index.md) | What `internal_version` means. `OBJ_VER_VERSION_TYPE_SPECIFIC` for a version number.

| `version.internal_version` | `int32` | The version number, starting from 1, when `type` is `OBJ_VER_VERSION_TYPE_SPECIFIC`. The server returns -1 with `OBJ_VER_VERSION_TYPE_LATEST`. |
| `version.external_repository_version` | `string` | Used only for objects in external repositories. Leave empty. |
| `version.external_repository_sort_key` | `int64` | Used only for objects in external repositories. Leave 0. |
