## Remarks

Supported when [ServerVaultCapabilities](https://developer.m-files.com/APIs/gRPC-API/Reference/Messages/MFiles.ServerVaultCapabilities/index.md)
`keep_upload_session_alive_supported` is true; otherwise the call fails with "Not implemented.".
Call it at the interval given in `SessionData.keep_upload_session_alive_interval_in_seconds` of
the login response while you hold an upload that you have not used yet. A removed or consumed
upload gives "Not found. (The specified upload session <id> does not exist.)".
