# POST /api/v3/submissions/{id}/files

`POST /api/v3/submissions/{id}/files`

## Request

- Base URL: `/` (relative, and the document was published on a file host, not at the API’s origin)
- URL: `/api/v3/submissions/{id}/files`
- Auth: HTTP bearer
- TypeScript: <https://skmtc.dev/wildmeorg/apis/wildbook-v3-api/docs/api/v3/submissions/:id/files/post.ts> (a function with typed inputs; its response is checked against the schema)

One image per request. Server computes digest. Serialize uploads; after a lost response GET manifest and reconcile name/digest and ETag. Same name/content at current revision is a retry success; differing content is 409. Incomplete files are never visible. File.name equals the original multipart filename used in Encounter.mediaAssetN. Reject unsafe names or names requiring cleaning; never silently rename. Same-content retries do not advance revision. Pilot: JPEG/PNG, matching extension, max 200 files and 200 MiB completed bytes per draft; exceeding either returns 413. At most one additional bounded retry candidate exists during upload. Staging must be configured. Serialize uploads; processing contention returns 429.
