Steps
Create an OAuth 2.0 client in Wallboard (or use the built-in client credentials) and obtain an access token via the authorization_code grant (PKCE required for public clients) or the legacy password grant for service accounts
Review docs.wallboard.us/docs/api/ for the content (/api/content) and playlist/simpleloop (/api/simpleLoop) resources, plus the unified read endpoint /api/v2/deviceContent
Query /api/v2/deviceContent filtered by contentGroupId to see the content/loop currently assigned to a screen or group
Call the relevant write endpoint to update the assigned content or playlist — plain PUT does a partial update on most fields
For a full playlist/data replacement, use the dedicated manage_playlist or manage_datasource endpoint rather than a plain PUT
Re-query deviceContent or the screen status endpoint to confirm the update propagated to the device
Known gotchas
Authentication is full OAuth 2.0 (authorization_code/PKCE, refresh_token, or legacy password grant) rather than a simple static API key for most endpoints — API keys are managed separately under system admin > integrations > API keys
PUT semantics are inconsistent: most fields update in place, but replacing playlist/datasource content requires the dedicated manage_playlist/manage_datasource endpoint instead of a plain PUT
Do not confuse this Wallboard (wallboard.us, digital signage, docs at docs.wallboard.us) with the unrelated 'Geomant Wallboard' contact-center product, which has a completely separate API
