1. The client application makes a POST call to the /Token/token endpoint. The POST body includes , among other parameters, a a username and password pair entered by the user.
   1. If the user entered the network name along with his or her their username and password, the client application includes the network name in the username (e.g. "username=exampleNetwork/exampleUser@brightsign.biz"). Otherwise, the network will need to be specified in a second POST call (see step 2a below).
2. If the credentials are valid, the server returns code 200 with a response body that includes access_token, expires_in, and refresh_token values. 
   1. If a network name was not specified in step 1, the response body will also include a networkNames array that lists networks associated with the specified username. The client application provides the list of networks to the user and allows him or her to select one. It then makes a second POST to the /token/ endpoint  endpoint with network name included in the username (e.g. "username=exampleNetwork/exampleUser@brightsign.biz").
3. If less than half of the expires_in time has elapsed (in seconds), and the client application has retained the access_token value in local storage, it includes the access_token in the "Authorization" header of each request to a BSN endpoint. The value of the "Authorization" header is specified as "Bearer {token_value}".
   1. If more than half of the expires_in time has elapsed, or if the access_token is not located in local storage, the client application makes a POST call to the /token/ endpoint  endpoint with the refresh_token value.
   2. If the refresh_token is not located in local storage, or if the expires_in time has elapsed (indicated by a 401 return from the server), the application indicates to the user that access to the BSN connection has been dropped (without loss of unsaved user data). It then prompts the user to enter access credentials again and returns to step 1 of the authentication process.

/token

...

POST

Posts user credentials or a refresh token to the /token/ endpointtoken endpoint. If the credentials are valid, the server returns an access/refresh token that is included with all other BSN REST calls for authentication.

URL Parameters

• grant_type: The type of grant being presented in exchange for the access token. This value must be set to "password".
• client_id: The client identifier. This value is currently not used by the server.
• client_secret: The client secret. This value is currently not used by the server.
• refresh_token: The refresh token to include when renewing the access token. When the refresh_token entry is included, the password does not need to be used.

...

• [string] access_token: The authorization token to use with endpoint calls until half of the expires_in time period has elapsed
• [string] token_type: The OAuth 2.0 token type, which will always be returned as "bearer"
• [integer] expires_in: The lifetime (in seconds) of the authorization token
• [string] refresh_token: The token to use for re-authentication when more than half of the expires_in time period has elapsed.
• [string[]]scope: An array that lists permissions the scope granted by the token. A successful Person Authentication Response will include the "Self" value only, indicating that a refresh token has not been granted, while a response including a refresh token while a successful User Authentication Response will contain both "Full" and "Self" values.

Examples

Person Authentication Request

The client application makes this authorization request when it does not have the network name. A successful response will include a list of network names.

...

The client application makes this authorization request when it has the network name, which can be retrieved either from user entry or from a Person Authentication Request. Note that the response body includes the roleName parameter, which allows the client application to determine the permissions scope and available functionality for the user.
