JSON Web Token (JWT) Authorization (recommended)

How to get a JWT

Using a JWT Config allows persistent connection to Box.

You will need a paid Box enterprise account, or you can sign up for a free developer account (make sure you are signed out of Box before clicking that link).

Visit the Box Developer Console and create a new application. Make sure the authorization type is JSON Web Token.

Go to Configuration > Add and Manage Public Keys and Generate a Public/Private Keypair. If you have not already, Box prompt you to set up 2 factor authentication and Authorize the application as an administrator in your box account. You will need to:

1. give the application App + Enterprise Access, and

2. enable the make API calls using the as-user header option

via the Box Application's Configuration page. Make sure to reauthorize the application if you are modifying these settings.

Base64 encoding JWT

To encode your JWT in Base64, you can use the following command in your terminal:

cat /path/to/your/box-jwt-config.json | base64

Replace /path/to/your/box-jwt-config.json with the actual path to your JWT configuration file. This will output the Base64 encoded JWT which you can then use in your environment variables.

      }
    }
  }
}

Developer Token Authorization (easiest)

Using a developer token is the easiest way to integrate with Box, but will only last 60 minutes.

To get started, set the BOX_DEV_TOKEN to a Box Developer Token.

Begin by visiting the Box Developer Console and create a new application. The authorization type does not currently matter, as all support Box Developer Token.

Once your application is created, navigate to its configuration setings and click Generate Developer Token.
