JSON Service

How to build a service and a template for it: JSON Services.

Templates built on it: Lottery (Brazil), Exchange Rates and Menu Board.

var dsplay_media = {
  // All general fields are also included...

  // JSON Service specific
  result: {}, // The service response, as an object
  rawResult: '{}', // The same response, as a string
}

The service URL may use ${...} variables, expanded by the player on each request: project.id, project.key, project.name, project.tags.<tag>, terminal.name, terminal.modified, terminal.tags.<tag>, terminal.lat and terminal.lon.

The player only shows the result while it is valid. An expiresAt (or legacy validity) in the past makes the media skip, unless the response has showOutdated: true. A response with an error key is never shown.
