## Remarks

**For M-Files components only.** The M-Files WOPI service calls it at the end of a save from
Office for the web. Applications should not call it.
- Changes the file content of the object. The object must be checked out, the token's link must
  be for editing or co-authoring, and the token's user needs read and edit access.
- Fails with "File size mismatch." when the uploaded byte count differs from
  `total_size_in_bytes` of the first upload call. The upload is deleted after the commit, also
  when the commit fails.
