Connect to Authorize.Net Data as a Linked Server

You can use the SQL Gateway to configure a TDS (SQL Server) remoting service and set up a linked server for Authorize.Net data. After you have started the service, you can use the UI in SQL Server Management Studio or call stored procedures to create the linked server. You can then work with Authorize.Net data just as you would a linked SQL Server instance.

Connect to Authorize.Net as an ODBC Data Source

If you have not already, first specify connection properties in an ODBC DSN (data source name). This is the last step of the driver installation. You can use the Microsoft ODBC Data Source Administrator to create and configure ODBC DSNs.

You can obtain the necessary connection properties on the Security Settings -> General Settings page after logging into your Merchant Account.

• UseSandbox: The Authorize.Net API to be used to process transactions. If you are using a production account, this property can be left blank. If you are using a developer test account, set this to 'TRUE'.
• LoginID: The API login Id associated with your payment gateway account. This property is used to authenticate that you are authorized to submit website transactions. Note that this value is not the same as the login Id that you use to log in to the Merchant Interface.
• TransactionKey: The transaction key associated with your payment gateway account. This property is used to authenticate that you are authorized to submit website transactions.

Configure the TDS Remoting Service

See the SQL Gateway Overview for a guide to configure a TDS remoting service in the SQL Gateway UI. The TDS remoting service is a daemon process that listens for TDS requests from clients.

Create a Linked Server for Authorize.Net Data

After you have configured and started the daemon, create the linked server and connect. You can use the UI in SQL Server Management Studio or call stored procedures.

Create a Linked Server from the UI

Follow the steps below to create a linked server from the Object Explorer.

1. Open SQL Server Management Studio and connect to an instance of SQL Server.
2. In the Object Explorer, expand the node for the SQL Server database. In the Server Objects node, right-click Linked Servers and click New Linked Server. The New Linked Server dialog is displayed.
3. In the General section, click the Other Data Source option and enter the following information after naming the linked server:
   • Provider: Select the SQL Server Native Client Provider that corresponds to your version of SQL Server. For example, SQL Server Native Client 11.0.

   • Data Source: Enter the host and port the TDS remoting service is running on, separated by a comma.

     Note that a value of "localhost" in this input refers to the machine where SQL Server is running so be careful when creating a linked server in Management Studio when not running on the same machine as SQL Server.

   • Catalog: Enter the CData system DSN, CData AuthorizeNet Sys.
4. In the Security section, select the option to have the connection "made using this security context" and enter the username and password of a user you created in the Users tab of the SQL Gateway.

Create a Linked Server Programmatically

In addition to using the SQL Server Management Studio UI to create a linked server, you can use stored procedures. The following inputs are required:

• server: The linked server name.
• provider: Enter "SQLNCLI", for the SQL Server Native Client Provider.

• datasrc: The host and port the service is running on, separated by a comma.

  Note that a value of "localhost" in the datasrc input refers to the machine where SQL Server is running, so be careful when creating a linked server in Management Studio when not running on the same machine as SQL Server.

• catalog: Enter the system DSN configured for the service.
• srvproduct: Enter the product name of the data source; this can be an arbitrary value, such as "CData SQL Gateway" or an empty string.

1. Call sp_addlinkedserver to create the linked server:

   EXEC sp_addlinkedserver @server='AuthorizeNet', @provider='SQLNCLI', @datasrc='< MachineIPAddress >,1434', @catalog='CData AuthorizeNet Sys', @srvproduct=''; GO

2. Call the sp_addlinkedsrvlogin stored procedure to allow SQL Server users to connect with the credentials of an authorized user of the service. Note that the credentials you use to connect to the service must specify a user you configured on the Users tab of the SQL Gateway.

   EXEC sp_addlinkedsrvlogin @rmtsrvname='AuthorizeNet', @rmtuser='admin', @rmtpassword='test', @useself='FALSE', @locallogin=NULL; GO

Connect from SQL Server Management Studio

SQL Server Management Studio uses the SQL Server Client OLE DB provider, which requires the ODBC driver to be used inprocess. You must enable the "Allow inprocess" option for the SQL Server Native Client Provider in Management Studio to query the linked server from SQL Server Management Studio. To do this, open the properties for the provider you are using under Server Objects -> Linked Servers -> Providers. Check the "Allow inprocess" option and save the changes.

Execute Queries

You can now execute queries to the Authorize.Net linked server from any tool that can connect to SQL Server. Set the table name accordingly:
