# Setting up a Box App

This processor requires a pre-configured App under the Account owning the resources being accessed (https://app.box.com/developers/console).

The App should have the following configuration:

- If you create a new App, select 'Server Authentication (with JWT)' authentication method.
  If you want to use an existing App, choose one with 'OAuth 2.0 with JSON Web Tokens (Server Authentication)' as Authentication method.
- Should have a 'Client ID' and 'Client Secret'.
- 'App Access Level' should be 'App + Enterprise Access'.
- 'Application Scopes' should have 'Write all files and folders in Box' enabled.
- 'Advanced Features' should have 'Generate user access tokens' and 'Make API calls using the as-user header' enabled.
- Under 'Add and Manage Public Keys' generate a Public/Private Keypair and download the configuration JSON file (under App Settings). The full path of this file should be set in the 'Box Config File' property.
  Note that you can only download the configuration JSON with the keypair details only once, when you generate the keypair. Also this is the only time Box will show you the private key.
  If you want to download the configuration JSON file later (under 'App Settings') - or if you want to use your own keypair - after you download it you need to edit the file and add the keypair details manually.
- After all settings are done, the App needs to be reauthorized on the admin page. ('Reauthorize App' at https://app.box.com/master/custom-apps.)
  If the app is configured for the first time it needs to be added ('Add App') before it can be authorized.
