After Installing the Connector you can connect and create a Data Source for data in Tableau CRM.

Setting Up a Data Source

Complete the following steps to connect to the data:

1. Under Connect | To a Server, click More....
2. Select the data source called Tableau CRM by CData.
3. Enter the information required for the connection.
4. Click Sign In.
5. If necessary, select a Database and Schema to discover what tables and views are available.

Using the Connection Builder

The connector makes the most common connection properties available directly in Tableau. However, it can be difficult to use if you need to use more advanced settings or need to troubleshoot connection issues. The connector includes a separate connection builder that allows you to create and test connections outside of Tableau.

There are two ways to access the connection builder:

• On Windows, use a shortcut called Connection Builder in the Start menu, under the CData Tableau Connector for Tableau CRM Analytics folder.
• You can also start the connection builder by going to the driver install directory and running the .jar file in the lib directory.

In the connection builder, you can set values for connection properties and click Test Connection to validate that they work. You can also use the Copy to Clipboard button to save the connection string. This connection string can be given to the Connection String option included in the connector connection window in Tableau.

Connecting to Tableau CRM

Tableau CRM uses the OAuth 2 authentication standard. You will need to obtain the OAuthClientId and OAuthClientSecret by registering an app with Tableau CRM. For further information, see Creating a Custom OAuth Application.

Set the AuthScheme to OAuthJWT.

Obtaining the OAuthJWT Consumer Key

To obtain the OAuthJWT consumer key:

1. Log in to Salesforce.com.
2. From Setup, enter Apps in the Quick Find box and then click the link to create an app. In the Connected Apps section of the resulting page, click New.
3. Enter a name to be displayed to users when they log in to grant permissions to your app, along with a contact Email address.
4. Click Enable OAuth Settings and enter a value in the Callback URL box. Set this value only to create the Connected App as it is required. It will not actually be needed for this type of authentication. The Callback URL is in the format:
   

   http://localhost:8019/src/oauthCallback.rst

5. Enable Use digital signatures.
6. Upload your certificate.
7. Select the scope of permissions that your app should request from the user.
8. Click your app name to open a page with information about your app. The OAuth consumer key is displayed.

After creating your OAuth Application, set the following connection properties:

• AuthScheme: OAuthJWT.
• InitiateOAuth: GETANDREFRESH.
• OAuthJWTCert: The JWT Certificate store.
• OAuthJWTPassword: The password of the JWT Certificate store.
• OAuthJWTIssuer: The OAuth Client ID.
• OAuthJWTCertType: The type of the certificate store specified by OAuthJWTCert.

Note: This flow never issues a refresh token.

Authenticating to Tableau CRM

The following subsections describe how to authenticate to Tableau CRM from three common authentication flows:

• Desktop: a connection to a server on the user's local machine, frequently used for testing and prototyping.
• Web: access to data via a shared website.
• Headless Server: a dedicated computer that provides services to other computers and their users, which is configured to operate without a monitor and keyboard.

For information about how to create a custom OAuth application, see Creating a Custom OAuth Application. For a complete list of connection string properties available in Tableau CRM, see Connection.

Desktop Applications

To authenticate with the credentials for a custom OAuth application, you must get and refresh the OAuth access token. After you do that, you are ready to connect.

Get and refresh the OAuth access token:

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

When you connect, the connector opens Tableau CRM's OAuth endpoint in your default browser. Log in and grant permissions to the application.

After you grant permissions to the application, the connector then completes the OAuth process:

1. The connector obtains an access token from Tableau CRM and uses it to request data.
2. The OAuth values are saved in the path specified in OAuthSettingsLocation. These values persist across connections.

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

Note: To configure the session timeout in Salesforce, navigate to Setup > Administration Setup > Security Controls > Session Settings.

Automatic refresh of the OAuth access token:

To have the connector automatically refresh the OAuth access token, do the following:

1. Before connecting to data for the first time, set the following connection parameters:
   • InitiateOAuth: REFRESH.
   • OAuthClientId: The client Id in your application settings.
   • OAuthClientSecret: The client secret in your application settings.
   • OAuthAccessToken: The access token returned by GetOAuthAccessToken.
   • OAuthSettingsLocation: The path where you want the connector to save the OAuth values, which persist across connections.
2. On subsequent data connections, set the following:
   • InitiateOAuth
   • OAuthSettingsLocation

Manual refresh of the OAuth access token:

The only value needed to manually refresh the OAuth access token is the OAuth refresh token.

1. To manually refresh the OAuthAccessToken after the ExpiresIn period (returned by GetOAuthAccessToken) has elapsed, call the RefreshOAuthAccessToken stored procedure.
2. Set the following connection properties:
   • OAuthClientId: The Client Id in your application settings.
   • OAuthClientSecret: The Client Secret in your application settings.

3. Call RefreshOAuthAccessToken with OAuthRefreshToken set to the OAuth refresh token returned by GetOAuthAccessToken.
4. After the new tokens have been retrieved, set the OAuthAccessToken property to the value returned by RefreshOAuthAccessToken. This opens a new connection.

Store the OAuth refresh token so that you can use it to manually refresh the OAuth access token after it has expired.
