# Confirm Upload

`GET /api/v1/files/{file_id_or_hashid}/confirm`

Confirm that a file was successfully uploaded to storage.

Call this endpoint after successfully uploading a file using the presigned URL
from /upload. This will verify the file exists, get the actual file size,
and mark it as completed.

Accepts either integer file_id (e.g., "4") or hashid (e.g., "npl94jxy").

This makes the file available for use in workflows.
