# Multipart Complete

`POST /api/storage/multipart/complete`

## Request

- Base URL: `https://api.tintin-x.com` (the document declares no server; this is the origin it was published from)
- URL: `https://api.tintin-x.com/api/storage/multipart/complete`
- Auth: HTTP bearer

Finalize the multipart upload. S3 validates every part's ETag and
rejects gaps or out-of-order sequences — the server-side sort is a
defensive belt-and-braces (browser concurrent queue may finish parts
out of order and hand them back in that order).
