Execute Stored Procedures to USPS in BizTalk

You can use stored procedures provided by the CData BizTalk Adapter for USPS to automate working with USPS data in BizTalk. Stored procedures implement actions available in the underlying API.

Stored procedures implement USPS actions that cannot be represented as SELECT, INSERT, UPDATE, and DELETE statements. This article shows how to generate a schema for a stored procedure. You can use the schema to execute the stored procedure from a send port.

Add the Adapter to Your Project

Use the Add Adapter wizard to add the adapter to a BizTalk Server project in Visual Studio. The adapter will return metadata about the inputs of the stored procedure and its results. This metadata is needed to create the schema.

  1. Right-click on the project in the Solution Explorer and click Add -> Add Generated Items.
  2. Select Add Adapter Metadata in the resulting dialog box.
  3. In the resulting Add Adapter wizard, select the adapter from the list.
  4. In the Port menu, leave the selection blank. Or, select a receive location or send port that has been configured to use the USPS Adapter.
  5. On the Connection String page, enter authentication credentials and other connection properties if they were not already configured in the send port or the receive location.

    Below is a typical connection string:

    PostageProvider=ENDICIA; RequestId=12345; Password='abcdefghijklmnopqr'; AccountNumber='12A3B4C'

    To authenticate with USPS, set the following connection properties.

    • PostageProvider: The postage provider to use to process requests. Available options are ENDICIA and STAMPS. If unspecified, this property will default to ENDICIA.
    • UseSandbox: This controls whether live or test requests are sent to the production or sandbox servers. If set to true, the Password, AccountNumber, and StampsUserId properties are ignored.
    • StampsUserId: This value is used for logging into authentication to the Stamps servers. This value is not applicable for Endicia and is optional if UseSandbox is true.
    • Password: This value is used for logging into Endicia and Stamps servers. If the postage provider is Endicia, this will be the pass phrase associated with your postage account. It is optional if UseSandbox is true.
    • AccountNumber: The shipper's account number. It is optional if UseSandbox is true.
    • PrintLabelLocation: This property is required to use the GenerateLabels or GenerateReturnLabels stored procedures. This should be set to the folder location where generated labels should be stored.

    The Cache Database

    Many of the useful task available from USPS require a lot of data. To ensure this data is easy to input and recall later, utilize a cache database to make requests. Set the cache connection properties in order to use the cache:

    • CacheLocation: The path to the cache location, for which a connection will be configured with the default cache provider. For example, C:\users\username\documents\uspscache

    As an alternative to CacheLocation, set the combination of CacheConnection and CacheProvider to configure a cache connection using a provider separate from the default.

Generate the Schema

After you enter connection properties in the Add Adapter wizard, the Schema wizard is displayed.

  1. On the next page, Schema Information, select the Send Port that you have configured to use the USPS Adapter.
  2. If you have configured the CData USPS Adapter in a solicit-response send port, disable the One-Way option.
  3. In the Command Type menu, select Stored Procedure.
  4. Select the stored procedure from the menu and enter the values for the input parameters.
  5. Confirm the settings in the summary displayed by the wizard and click Finish to generate the schema.xsd file.
