Overview

The Remote DWS allows you to view and modify settings on a BrightSign player over the Internet. The Remote DWS API is a REST framework that allows a client application to integrate with Remote DWS functionality.

The client application makes REST calls to the BrightSign WebSockets server, which in turn sends WebSockets messages to BrightSign players. Depending on the operation, the BrightSign player may return information to the BrightSign Websockets server, which will be relayed in the server REST response to the client application.

REST URLs

The following URLs are case sensitive, and the server may return code 426 if the case is not matched exactly.

Production Remote DWS Server: https://ws.bsn.cloud/rest/v1/

Production Authentication URL: https://api.bsn.cloud/2022/06/REST/Token/

Authentication

All Remote DWS calls require a valid authentication token. The target player must belong to the same network for which the token has been granted.

Authentication is carried out using the same OAUTH endpoint as other BSN.cloud services. See Main REST HTTP API version 2022/06 | MainRESTHTTPAPIversion2022/06 AuthenticationWorkflow.

Request Message Format

HTTP requests to Remote DWS resources must be JSON formatted and contain the following URL parameters:

• destinationType  string: The device type. The only currently accepted value is "player".

• destinationName  string: The device serial number

Requests that require a JSON body need to have an outer data object. For instance, if a route expects [bool] enabled then the full JSON body would look like:

Some requests also require resource-specific properties in the URL or request body, as detailed in the URL Parameters and Request Body sections below.

Response Message Format

The server will respond to a REST request with a success or error message, which may also contain resource-specific properties, as detailed in the Response Body sections below.

Returned JSON objects will have an outer object containing the methods below, where data is an error or a result object containing the returned values:

• route string: The route the request was sent to

• method string: The request method

• data object: The returned data

For example:

Request Example

GET /re-provision/ 

Calling this endpoint will re-provision the player (in other words, the B-Deploy setup currently associated with the player will be downloaded, and the device will go through setup again).

The re-provision process involves the following steps:

1. If the “networking” section of the player’s registry contains the access and refresh tokens, it is assumed that the player was previously set up for BSN.cloud. So BrightSign keeps some setup-related keys in the networking section (these keys are listed at right) and deletes the rest of the registry entries. If the networking section does not include access and refresh tokens, it will empty the whole networking section, format the SD card, and reboot to try to provision the player.

2. BrightSign also sets the “deviceSetupComplete“ parameter in the “autorun” section to null, so that the player can set up again. This key is set to 1 only if the player was previously set up through the on-device setup option.

3. The code removes all files from the default storage device (this is almost always the SD card). You do not need to format the storage separately.

4. The player reboots, fetches the setup package from B-Deploy, and re-provisions itself.

Response Body

• success bool: True means that the operation succeeded, False means that the operation failed. If the operation is successful, the player will reboot.
