How It Works

Remote Feeds let you serve content to Concerto 3 from any URL you control, allowing content to dynamically change and update without requiring manual uploads or moderation. The Concerto server polls the URL on a schedule and creates or updates content based on what the endpoint returns.

Your endpoint must return a JSON array of Content objects. The URL path is entirely up to you, any publicly accessible URL that returns the correct format will work.

For example, https://remotefeed-quotes-demo.concerto-signage.org/feed returns a quote of the day.

Details

Concerto 3 uses the combination of type + name as a stable identity for each item. When a refresh returns an item matching an existing record's type and name, the record is updated in place. If either changes, the old content is removed and a new record is created, so keep type and name stable when the content is semantically the same. Consider evergreen titles like "Weather" instead of "Weather - Mar 9, 2026", and opt to put that level of detail into the content body itself (since the name is not shown on screens anyways).
