Enabling SSIS in Visual Studio 2022

If you're using Visual Studio 2022, you will need to install the SQL Server Integration Services Projects extension to use SSIS.

1. Navigate to Extensions > Manage Extensions.
2. In the Manage Extensions window's search box, search for "SQL Server Integration Services Projects 2022" and select the extension in the list.
3. Click Download.
4. Close Visual Studio and run the downloaded Microsoft.DataTools.IntegrationServices.exe installer. Proceed through the installer with default settings.
5. Open Visual Studio. There should now be an "Integration Services Project" project template available.

Adding the Zendesk Connection Manager

Create a new connection manager as follows:

1. Create a Visual Studio project with the "Integration Services Project" template.
2. In the project, right-click within the Connection Managers window and select New Connection from the menu.
3. In the Description column, select CData Zendesk Connection Manager and click Add...
4. Configure the component as described in the next section.

Alternatively, if you have an existing project and CData Zendesk Source or CData Zendesk Destination:

1. Right-click your CData Zendesk source or destination component in your data flow
2. Select Edit... to open an editor window.
3. Click the New... button next to the Connection manager: dropdown selector to create a connection manager.
4. Configure the component as described in the next section.

Connecting to Zendesk

To connect to Zendesk, set the URL (Zendesk Support URL), using the format https://{subdomain}.zendesk.com. Once connected, user authenticate as described in the following section.

In addition, users who work with archived data for the TicketMetrics table must set the UseIncrementalAPI property to True.

Authenticating to Zendesk

Zendesk supports two types of authentication, depending on whether the user is connecting directly to their own local data (basic authentication) or connecting to shared data via a browser (OAuth authentication).

Basic Authentication

To use Basic authentication, specify an email address and either a Password or an ApiToken. Set User to your email address, and then use the Zendesk Support admin interface to do the following:

1. Enable password access.
2. Set AuthScheme to Basic while using APIToken Authentication.
3. At Admin > Channels > API, manage API tokens. Only one token can be active at a time. Deleting a token deactivates it permanently.

OAuth Authentication

Zendesk supports OAuth authentication for all instances where the user is accessing shared data via the network. This means that, regardless of whether authentication originates at the Web, a Desktop, or a Headless Server, you must set AuthScheme to OAuth, and you must create a custom OAuth application.

The following subsections describe how to authenticate to Zendesk 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 Zendesk, 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 component opens Zendesk's OAuth endpoint in your default browser. Log in and grant permissions to the application.

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

1. The component obtains an access token from Zendesk 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 component refreshes it automatically.

Automatic refresh of the OAuth access token:

To have the component 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 component to save the OAuth values, which persist across connections.
2. On subsequent data connections, set the following:
   • InitiateOAuth
   • OAuthSettingsLocation

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 component 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. Do the following:

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

   Set the following properties:

   • InitiateOAuth = OFF.
   • OAuthClientId = the client Id assigned when you registered your application.
   • OAuthClientSecret = the client secret assigned when you registered your 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 component. 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, set the following connection properties to obtain the OAuth authentication values:

   • 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.
   • 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. After you re-set the following properties, you are ready to connect:

   • 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 component.
   • OAuthClientId = the client Id assigned when you registered your application.
   • OAuthClientSecret = the client secret assigned when you registered your 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 the following 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 component.
• OAuthClientId = the client Id assigned when you registered your custom OAuth application.
• OAuthClientSecret = the client secret assigned when you registered your custom OAuth application.
