Steps
Authenticate via OAuth2 client credentials
POST /api/fonts with a multipart upload of the .ttf/.otf file
GET /api/fonts to confirm registration and capture the returned font family name/id
Reference the uploaded font family in a Text/Ticker widget's style properties when creating or updating a Layout via the API
Send a Collect Now command (or wait for the next sync interval) so displays download the new font alongside their next layout XLF
Known gotchas
Players cache fonts locally and only re-download when the CMS font manifest hash changes, so overwriting a font under the same name without deleting the old record can leave stale glyphs cached on already-synced players
The API does not enforce font-embedding license flags — a no-embed font uploads successfully but may render incorrectly or fall back to a default on the player
Large CJK/non-Latin font files are not subsetted server-side, so bulk font uploads can noticeably bloat player storage and sync time across a large fleet
