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

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 eBay 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 eBay 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 eBay APIs

Set the following to connect to eBay:

• SiteID: Set this to the eBay site ID. By default this is "0" (the U.S. site).
• UseSandbox: Set this to True to use a eBay sandbox account. By default, the connector connects to production environments.
• RuName: Set this to the RuName (eBay Redirect URL name) that you will use to sign-in. Find this in your eBay Sign-in Settings.

Authenticating to eBay

The connector can authenticate to eBay using either the OAuth 2.0 authentication standard or Auth'n'Auth, the traditional authentication used by the eBay APIs.

User Accounts (OAuth)

Set AuthScheme to OAuth.

Desktop Applications

You need to create a custom OAuth application. See Creating a Custom OAuth App for information about creating custom applications.

Get and Refresh the OAuth Access Token

After setting the following, you are ready to connect:

• InitiateOAuth: Set this to GETANDREFRESH. You can use InitiateOAuth to avoid repeating the OAuth exchange and manually setting the OAuthAccessToken.
• OAuthClientId: Set this to the App ID (Client ID) in your keyset.
• OAuthClientSecret: Set this to the Cert ID (Client Secret) in your keyset.
• CallbackURL: Set to a URL containing the server name and port of the device running the connector. Any localhost address is usable. The default callback URL is: http://localhost:33333.

When you connect, the connector opens eBay's OAuth endpoint in your default browser. Log in and grant permissions to the application. The connector then completes the OAuth process:

1. The connector obtains an access token from eBay and uses it to request data.
2. The OAuth values are saved in the location specified in OAuthSettingsLocation, to be persisted across connections.

The connector refreshes the access token automatically when it expires.

User Accounts with Legacy Apps (Auth'n'Auth)

The connector can authenticate using eBay's legacy Auth'n'Auth protocol. Select this authentication scheme if you're using an older application that was built to use Auth'n'Auth.

Set AuthScheme to AuthNAuth.

You need to create a custom OAuth application. See Creating a Custom OAuth App for more information.

Access Token

An OAuthAccessToken is required when authenticating via Auth'n'Auth. Set the following connection properties to obtain the OAuthAccessToken:

• OAuthClientId: Set this to the App ID (Client ID) in your keyset.
• OAuthClientSecret: Set this to the Cert ID (Client Secret) in your keyset.
• DevID: Set this to the Developer ID from your keyset.

Then call stored procedures to complete the token exchange:

1. Call the GetOAuthAuthorizationURL stored procedure. Set the RuName input to the eBay Redirect URL you specified in your app settings. The stored procedure returns the URL to the OAuth endpoint.

2. Navigate to the URL that the stored procedure returned in Step 1. Log in, and authorize the web application. After authenticating, the browser redirects you to the redirect URI. There will be a parameter called sessionid appended to the redirect URI. Note the value of this parameter. If you are using the recommeded https://oauth.cdata.com/oauth/ as your "auth accepted URL", the value will be BASE64 encoded and will need to be decoded before proceeding.
3. Call the GetOAuthAccessToken stored procedure. Set the AuthMode input to WEB. Set the SessionId input parameter to either the value of the 'sessionid' in the query string of the authorization URL or the BASE64 decoded session ID from the callback URL.

Set the following connection properties to connect to data:

• OAuthClientId: Set this to the App ID (Client ID) in your keyset.
• OAuthClientSecret: Set this to the Cert ID (Client Secret) in your keyset.
• OAuthAccessToken: Set this to the Auth'n'Auth token returned by GetOAuthAccessToken.

  Note: Auth'n'Auth tokens expire after 18 months. You will need to generate a new token after the token expires.

• DevID: Set this to the Developer ID from your keyset.
