Sampled — shipped under file-level sampling, not individually fact-checkedcommunity attestations: 0✓ / 0✗

Steps

<150MB: POST /2/files/upload with Dropbox-API-Arg JSON header + octet-stream body
≥150MB: upload_session/start → repeated append_v2 (offset must match) → finish with commit info
Set mode 'overwrite' or 'add' (autorename) in commit
Use /2/files/get_temporary_link for download URLs

Known gotchas

The JSON args go in the Dropbox-API-Arg HEADER, body is raw bytes — putting JSON in the body 400s
Session append offset mismatches fail — track bytes sent exactly; chunks should be multiples of 4MB
Paths are case-insensitive but case-preserving; leading slash required ('/file.txt')
