This section shows how to set up ODBC connectivity and configure DSNs on macOS.

Minimum macOS Version

The CData ODBC Driver for Sage Business Cloud Accounting driver requires macOS Sierra (10.12) or above.

Licensing the Driver

In a terminal, run the following commands to license the driver. To activate a trial, omit the <key> input.

cd "/Applications/CData ODBC Driver for Sage Business Cloud Accounting/bin"
sudo ./install-license.sh <key>

You'll be prompted for a name and password. These refer to your name and your machine's password.

Authenticating to Sage Business Cloud Accounting

Sage Business Cloud Accounting provides embedded OAuth credentials that simplify connection from a Desktop application or a Headless machine. To connect from a Web application, you must create a custom OAuth application, as described in Creating a Custom OAuth Application.

To connect via OAuth from all authentication flows, you must set AuthScheme to OAuth.

The following subsections describe how to authenticate to Sage Business Cloud Accounting from the available oauth flows. For information about how to create a custom OAuth application, and why you might want to create one even for auth flows that already have embedded OAuth credentials, see Creating a Custom OAuth Application.

For a complete list of connection string properties available in Sage Business Cloud Accounting, see Connection.

Desktop Applications

CData provides an embedded OAuth application that simplifies authentication at the desktop; that is, in situations where the user is using a local server not connected to the internet.

You can also authenticate from the desktop via a custom OAuth application, which you configure and register at the Sage Business Cloud Accounting console. For further information, see Creating a Custom OAuth Application.

Before you connect, set these properties:

• InitiateOAuth: GETANDREFRESH. Used to automatically get and refresh the OAuthAccessToken.
• Custom OAuth applications only:
  • OAuthClientId: The client Id assigned when you registered your custom OAuth application.
  • OAuthClientSecret: The client secret assigned when you registered your custom OAuth application.
  • CallbackURL: The redirect URI defined when you registered your custom OAuth application.

When you connect, the driver opens Sage Business Cloud Accounting's OAuth endpoint in your default browser. Log in and grant permissions to the application.

When the access token expires, the driver refreshes it automatically.

Headless Machines

If you need to log in to a resource that resides on a headless machine, you must authenticate on another device that has an internet browser. You can do this in either of the following ways:

• Option 1: Obtain the OAuthVerifier value.
• Option 2: Install the driver on a machine with an internet browser and transfer the OAuth authentication values after you authenticate through the usual browser-based flow.

After you execute either Option 1 or Option 2, configure the driver to automatically refresh the access token on the headless machine.

Option 1: Obtaining and Exchanging a Verifier Code

To obtain a verifier code, you must authenticate at the OAuth authorization URL as follows:

1. Authenticate from the machine with an internet browser, and obtain the OAuthVerifier connection property.

   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 these properties:

   • InitiateOAuth: OFF.
   • OAuthClientId: The client Id assigned when you registered your custom OAuth application.
   • OAuthClientSecret: The client secret assigned when you registered your custom OAuth application.

2. Call the GetOAuthAuthorizationURL stored procedure. The stored procedure returns the CallbackURL established when the custom OAuth application was registered. (See Creating a Custom OAuth Application.)

   Copy this URL and paste it into a new browser tab.

3. Log in and grant permissions to the driver. The OAuth application redirects you the redirect URI, with a parameter called code appended. Note the value of this parameter; you will need it later, to configure the OAuthVerifier connection property.

4. Exchange the OAuth verifier code for OAuth refresh and access tokens. On the headless machine, to obtain the OAuthAccessToken, set these connection properties:

   • InitiateOAuth: REFRESH.
   • OAuthVerifier: The noted verifier code (the value of the code parameter in the redirect URI).
   • OAuthSettingsLocation: persist the encrypted OAuth authentication values to the specified file.
   • Custom OAuth applications only:
     • OAuthClientId: The client Id in your custom OAuth application settings.
     • OAuthClientSecret: The client secret in the custom OAuth application settings.

5. Test the connection to generate the OAuth settings file.

6. You are ready to connect after you re-set these properties:

   • InitiateOAuth: REFRESH.
   • OAuthSettingsLocation: The file containing the encrypted OAuth authentication values. To enable the automatic refreshing of the access token, be sure that this file gives read and write permissions to the driver.
   • Custom OAuth applications only:
     • OAuthClientId: The client Id assigned when you registered your custom OAuth application.
     • OAuthClientSecret: The client secret assigned when you registered your custom OAuth application.

Option 2: Transferring OAuth Settings

Prior to connecting on a headless machine, you must install and create a connection with the driver on a device that supports an internet browser. Set the connection properties as described above in "Desktop Applications".

After completing the instructions in "Desktop Applications", the resulting authentication values are encrypted and written to the path 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.

To connect to data via the headless machine, set these connection properties:

• InitiateOAuth: REFRESH
• OAuthSettingsLocation: The path to the OAuth settings file you copied from the machine with the browser. To enable automatic refreshing of the access token, ensure that this file gives read and write permissions to the driver.
• Custom OAuth applications only:
  • OAuthClientId: The client Id assigned when you registered your custom OAuth application.
  • OAuthClientSecret: The client secret assigned when you registered your custom OAuth application.

Uninstalling the Driver

The easiest way to uninstall the driver is to open a terminal and run the included uninstall.sh script, located in the installation directory. For example:

cd "/Applications/CData ODBC Driver for Sage Business Cloud Accounting"
sudo ./uninstall.sh

Note: The script needs to be run from the installation directory.
