The Box API uses OAuth2 for authentication, which can be difficult to implement. The SDK makes it easier by providing classes that handle obtaining tokens and automatically refreshing them.
The fastest way to get started using the API is with developer tokens. A developer token is simply a short-lived access token that cannot be refreshed and can only be used with your own account. Therefore, they're only useful for testing an app and aren't suitable for production. You can obtain a developer token from your application's developer console.
The following example creates an API connection with a developer token:
BoxAPIConnection api = new BoxAPIConnection("YOUR-DEVELOPER-TOKEN");
Using an auth code is the most common way of authenticating with the Box API. Your application must provide a way for the user to login to Box (usually with a browser or web view) in order to obtain an auth code.
After a user logs in and grants your application access to their Box account,
they will be redirected to your application's redirect_uri
which will contain
an auth code. This auth code can then be used along with your client ID and
client secret to establish an API connection.
BoxAPIConnection api = new BoxAPIConnection("YOUR-CLIENT-ID",
"YOUR-CLIENT-SECRET", "YOUR-AUTH-CODE");
In certain advanced scenarios, you may want to obtain an access and refresh token yourself through manual calls to the API. In this case, you can create an API connection with the tokens directly.
BoxAPIConnection api = new BoxAPIConnection("YOUR-CLIENT-ID",
"YOUR-CLIENT-SECRET", "YOUR-ACCESS-TOKEN", "YOUR-REFRESH-TOKEN");
By default, a BoxAPIConnection
will automatically refresh the access token if
it has expired. To disable auto-refresh, set the connection's auto-refresh
setting to false with setAutoRefresh(false)
. Keep in mind that
you will have to manually refresh the access token yourself.
// This connection won't auto-refresh.
BoxAPIConnection api = new BoxAPIConnection("YOUR-CLIENT-ID",
"YOUR-CLIENT-SECRET", "YOUR-ACCESS-TOKEN", "YOUR-REFRESH-TOKEN");
api.setAutoRefresh(false);
// If the access token expires, you will have to manually refresh it.
api.refresh();
