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

Builds the definitions of a new workspace tab view and its reverse view for a pair of object
types, without saving the views.

- **Service:** [Workspaces](https://developer.m-files.com/APIs/gRPC-API/Reference/MFiles.IRPCWorkspace/index.md) `MFiles.IRPCWorkspace`
- **gRPC method:** `/MFiles.IRPCWorkspace/CreateTemporaryWorkspaceView`
- **HTTP (mf-http-grpc):** `POST /grpc/v1/create-temporary-workspace-view`
- **Request:** [`CreateTemporaryWorkspaceViewRequest`](https://developer.m-files.com/APIs/gRPC-API/Reference/MFiles.IRPCWorkspace/CreateTemporaryWorkspaceView/index.md#request)
- **Response:** [`CreateTemporaryWorkspaceViewResponse`](https://developer.m-files.com/APIs/gRPC-API/Reference/MFiles.IRPCWorkspace/CreateTemporaryWorkspaceView/index.md#response)
- **Book and level:** Vault API, standard
- **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

- Requires a vault session. No special vault rights are needed.
- Both IDs must be real object types; a value list fails with "The parameter is incorrect.".
- The returned views are not saved and have no name. They are located under the pair's
  filter-only view and give read access to all users. Set the name and any other fields, then
  save a view with [AddNewView](https://developer.m-files.com/APIs/gRPC-API/Reference/MFiles.IRPCViews/AddNewView/index.md).
- Side effect: the first call for a pair of object types creates and saves the pair's hidden
  filter-only view, which later calls reuse.
