Connecting to Box
Connecting to Box
Use the OAuth authentication standard to connect to Box. You can authenticate with a user account or with a service account. A service account is required to grant organization-wide access scopes to the cmdlet. The cmdlet facilitates these authentication flows as described below.
User Accounts (OAuth)
AuthScheme must be set to OAuth in all user account flows.
Desktop Applications
CData provides an embedded OAuth application that simplifies OAuth desktop Authentication. Alternatively, you can create a custom OAuth application. See Create a Custom OAuth App for information about creating custom applications and reasons for doing so.Get and Refresh the OAuth Access Token
After setting the following, you are ready to connect:
- OAuthClientId (custom applications only): Set this to the client Id assigned when you registered your app.
- OAuthClientSecret (custom applications only): Set this to the client secret assigned when you registered your app.
- CallbackURL (custom application only): Set this to the redirect URI defined when you registered your app. For example: http://localhost:33333
Headless Machines
To configure the driver, use OAuth with a user account on a headless machine. You need to authenticate on another device that has an internet browser.
- Choose one of two options:
- Option 1: Obtain the OAuthVerifier value as described in "Obtain and Exchange a Verifier Code" below.
- Option 2: Install the cmdlet on a machine with an internet browser and transfer the OAuth authentication values after you authenticate through the usual browser-based flow.
- Then configure the cmdlet to automatically refresh the access token on the headless machine.
Option 1: Obtain and Exchange a Verifier Code
To obtain a verifier code, you must authenticate at the OAuth authorization URL.
Follow the steps below to authenticate from the machine with an internet browser and obtain the OAuthVerifier connection property.
- Choose one of these options:
- If you are using the Embedded OAuth Application, call the GetOAuthAuthorizationURL stored procedure. Open the URL returned by the stored procedure in a browser.
- If you are using a custom OAuth application, set the following properties:
- InitiateOAuth: Set to OFF.
- OAuthClientId: Set to the client Id assigned when you registered your application.
- OAuthClientSecret: Set to the client secret assigned when you registered your application.
- Log in and grant permissions to the cmdlet. You are then redirected to the redirect URI. There will be a parameter called code appended to the redirect URI. Note the value of this parameter. Later you will set this in the OAuthVerifier connection property.
On the headless machine, set the following connection properties to obtain the OAuth authentication values:
- InitiateOAuth: Set this to REFRESH.
- OAuthVerifier: Set this to the noted verifier code (the value of the code parameter in the redirect URI).
- OAuthClientId: (custom applications only) Set this to the client Id in your custom OAuth application settings.
- OAuthClientSecret: (custom applications only) Set this to the client secret in the custom OAuth application settings.
- OAuthSettingsLocation: Set this to persist the encrypted OAuth authentication values to the specified location.
Test the connection to generate the OAuth settings file, then re-set the following properties to connect:
- InitiateOAuth: Set this to REFRESH.
- OAuthClientId: (custom applications only) Set this to the client Id assigned when you registered your application.
- OAuthClientSecret: (custom applications only) Set this to the client secret assigned when you registered your application.
- OAuthSettingsLocation: Set this to the location containing the encrypted OAuth authentication values. Make sure this location gives read and write permissions to the cmdlet to enable the automatic refreshing of the access token.
Option 2: Transfer OAuth Settings
Prior to connecting on a headless machine, you need to install and create a connection with the driver on a device that supports an internet browser. Set the connection properties as described in "Desktop Applications" above.
After completing the instructions in "Desktop Applications", the resulting authentication values are encrypted and written to the location specified by OAuthSettingsLocation. The default filename is OAuthSettings.txt.
Test the connection to generate the OAuth settings file, then copy the OAuth settings file to your headless machine.
On the headless machine, set the following connection properties to connect to data:
- InitiateOAuth: Set this to REFRESH.
- OAuthClientId: (custom applications only) Set this to the client Id assigned when you registered your application.
- OAuthClientSecret: (custom applications only) Set this to the client secret assigned when you registered your application.
- OAuthSettingsLocation: Set this to the location of the OAuth settings file you copied from the machine with the browser. Make sure this location gives read and write permissions to the cmdlet to enable the automatic refreshing of the access token.
Authenticate with a Service Account
Set the AuthScheme to OAuthJWT to authenticate with this method.
Service accounts have silent authentication, without user authentication in the browser. You can also use a service account to delegate enterprise-wide access scopes to the cmdlet.
You need to create an OAuth application in this flow. See Create a Custom OAuth App to create and authorize an app. You can then connect to Box data that the service account has permission to access.
After setting the following connection properties, you are ready to connect:
- OAuthClientId: Set to the Client Id in your app settings.
- OAuthClientSecret: Set to the Client Secret in your app settings.
- OAuthJWTCertType: Set to "PEMKEY_FILE".
- OAuthJWTCert: Set to the path to the .pem file you generated.
- OAuthJWTCertPassword: Set to the password of the .pem file.
- OAuthJWTCertSubject: Set to "*" to pick the first certificate in the certificate store.
- OAuthJWTSubjectType: Set to "enterprise" or "user" depending on the Application Access Value you selected in your app settings. The default value of this connection property is "enterprise".
- OAuthJWTSubject: Set to your enterprise Id if your subject type is set to "enterprise" or your app user Id if your subject type is set to "user".
- OAuthJWTPublicKeyId: Set to the Id of your public key in your app settings.
