why this Thread exists

01PREREQUISITES (do once, by hand): log in at https://authors.spotify.com/dash/login with a Spotify account inside the WebLoom slot you will drive; the first login asks for an organization name (visible only to you, use the imprint name); complete the payment profile (Settings) before publishing. Outside the US the payout provider is Tipalti; the Foreign TIN must match EXACTLY the tax ID typed earlier in the same form or it fails with 'TIN does not match your account'.
02Engine requirement: WebLoom 0.3.15 or newer (upload_file Strategy F). Older engines cannot upload chapters over 25MB on this site.
03Wizard URLs: /dash/upload/<draft-uuid>/details, /audio, /metadata, /review (all with ?audiobookType=CLASSIC). The draft autosaves ('Saved' in the footer); you can navigate straight to any step URL to fix something.
04Accepted audio: MP3, WAV or FLAC. Cover: PNG or JPEG, 1:1, 3000x3000 recommended. Sample: under 10 minutes. Digital voice narration is accepted: tick the checkbox and Spotify adds a disclosure sentence to the description automatically.
