# Delete Upload

DELETE https://api.onepin.ai/api/v1/uploads/{upload_id}

Delete an upload and its associated file.

Permanently removes the upload record and schedules the stored file for
deletion. The record is removed first; the file is cleaned up asynchronously
after the response so storage removal only happens after a successful commit.

If the upload was previously confirmed against a workspace-scoped resource,
the consumed storage bytes are released back to the workspace quota, keeping
the workspace storage counter accurate.

Callers can delete uploads in any state (`pending` or `uploaded`). Deleting
a `pending` upload (e.g. after an expired presigned URL) is the correct way
to clean up an abandoned upload attempt.

Delete is owner-scoped: the lookup is limited to the caller's own uploads, so no
workspace-role gate applies — a caller can only remove their own upload, never another
member's workspace content.

Dual-auth: Bearer JWT or API key (scope `uploads:write`).
