These APIs allow you to connect to individual BrightSign players. They are especially useful if there are many devices on the network so you can more quickly find and access players.
Local DWS APIs let you access your players on a local network. These APIs give you information about the player, let you reboot the player, see the health of SD card, and access all of the functionality of the calls that underlie the DWS in the BrightAuthor:connected UI. The local DWS APIs include Presentation Autorun Server APIs, which are hosted by the presentation autorun, and can be accessed with authentication from the local DWS. Only BrightScript objects in the presentation autorun know how to respond to these requests. Local DWS APIs are local player APIs and are authenticated through a username and password, not an OAuth bearer token.
Remote DWS APIs allow you to access your player through BSN.cloud (using the bearer token for bsn.cloud) as well as get information about the player, reboot the player, see the health of SD card, and access all of the functionality of the calls that underlie the DWS in the BrightAuthor:connected UI.
Note that Local Web Server APIs are remote player APIs which let you access and modify user variables over a local network.
