Connect to PayPal Data from PowerBuilder

This article demonstrates how to access PayPal data from PowerBuilder using the CData ADO.NET Provider for PayPal.

The CData ADO.NET providers are easy-to-use, standards-based controls that can be used from any platform or development technology that supports Microsoft .NET, including PowerBuilder. This article shows how to use the CData ADO.NET Provider for PayPal in PowerBuilder.

This article shows how to create a basic PowerBuilder application that uses the CData ADO.NET Provider for PayPal to retrieve data.

  1. In a new WPF Window Application solution, add all the Visual Controls needed for the connection properties. Below is a typical connection string:

    Schema=SOAP;Username=sandbox-facilitator_api1.test.com;Password=xyz123;Signature=zx2127;InitiateOAuth=GETANDREFRESH

    The provider surfaces tables from two PayPal APIs. The APIs use different authentication methods.

    • The REST API uses the OAuth standard. To authenticate to the REST API, you will need to set the OAuthClientId, OAuthClientSecret, and CallbackURL properties.
    • The Classic API requires Signature API credentials. To authenticate to the Classic API, you will need to obtain an API username, password, and signature.

    See the "Getting Started" chapter of the help documentation for a guide to obtaining the necessary API credentials.

    To select the API you want to work with, you can set the Schema property to REST or SOAP. By default the SOAP schema will be used.

    For testing purposes you can set UseSandbox to true and use sandbox credentials.

  2. Add the DataGrid control from the .NET controls.
  3. Configure the columns of the DataGrid control. Below are several columns from the Account table: <DataGrid AutoGenerateColumns="False" Margin="13,249,12,14" Name="datagrid1" TabIndex="70" ItemsSource="{Binding}"> <DataGrid.Columns> <DataGridTextColumn x:Name="idColumn" Binding="{Binding Path=Id}" Header="Id" Width="SizeToHeader" /> <DataGridTextColumn x:Name="nameColumn" Binding="{Binding Path=Date}" Header="Date" Width="SizeToHeader" /> ... </DataGrid.Columns> </DataGrid>
  4. Add a reference to the CData ADO.NET Provider for PayPal assembly.

Connect the DataGrid

Once the visual elements have been configured, you can use standard ADO.NET objects like Connection, Command, and DataAdapter to populate a DataTable with the results of an SQL query:

System.Data.CData.PayPal.PayPalConnection conn conn = create System.Data.CData.PayPal.PayPalConnection(connectionString) System.Data.CData.PayPal.PayPalCommand comm comm = create System.Data.CData.PayPal.PayPalCommand(command, conn) System.Data.DataTable table table = create System.Data.DataTable System.Data.CData.PayPal.PayPalDataAdapter dataAdapter dataAdapter = create System.Data.CData.PayPal.PayPalDataAdapter(comm) dataAdapter.Fill(table) datagrid1.ItemsSource=table.DefaultView

The code above can be used to bind data from the specified query to the DataGrid.
