# POST /api/cascade-tracing/documents/replace

`POST /api/cascade-tracing/documents/replace`

## Request

- Base URL: `https://api.retraced.com` (the document declares no server; this is the origin it was published from)
- URL: `https://api.retraced.com/api/cascade-tracing/documents/replace`
- Auth: none declared

Replaces a tracing document the caller's company uploaded with one of its uploaded files. The old document is removed and a new one — same type, same Order Hub order, named after the new file — is attached to the purchase order's link; the file is moved to the private bucket. 404 `not_found` (purchase order, document or link missing or removed), 403 `insufficient_rights` (another company's document), 400 `document_type_not_valid` (`documentType` differs from the document's type), 404 `invalid_document_id` (the file is not the caller's). The links' document figures are refreshed in the background.
