Consume Adobe Commerce OData Feeds in PowerBuilder
This article demonstrates how to consume Adobe Commerce data as OData feeds from PowerBuilder using the API Server.
The CData API Server, when paired with the ADO.NET Provider for Adobe Commerce (or any of 200+ other ADO.NET Providers), produces secure feeds of Adobe Commerce data that you can consume in PowerBuilder DataWindows. The API Server supports the major Web services, including OData, Atom, JSON, HTML, CSV, TSV, and RSS. It also supports the major authentication schemes and SSL.
This article shows how to create a DataWindow that uses the CData API Server to execute reads and writes.
Set Up the API Server
Follow the steps below to begin producing secure Adobe Commerce OData services:
Deploy
The API Server runs on your own server. On Windows, you can deploy using the stand-alone server or IIS. On a Java servlet container, drop in the API Server WAR file. See the help documentation for more information and how-tos.
The API Server is also easy to deploy on Microsoft Azure, Amazon EC2, and Heroku.
Connect to Adobe Commerce
After you deploy the API Server and the ADO.NET Provider for Adobe Commerce, provide authentication values and other connection properties needed to connect to Adobe Commerce by clicking Settings -> Connections and adding a new connection in the API Server administration console.
Adobe Commerce uses the OAuth 1 authentication standard. To connect to the Adobe Commerce REST API, obtain values for the OAuthClientId, OAuthClientSecret, and CallbackURL connection properties by registering an app with your Adobe Commerce system. See the "Getting Started" section in the help documentation for a guide to obtaining the OAuth values and connecting.
You will also need to provide the URL to your Adobe Commerce system. The URL depends on whether you are using the Adobe Commerce REST API as a customer or administrator.
Customer: To use Adobe Commerce as a customer, make sure you have created a customer account in the Adobe Commerce homepage. To do so, click Account -> Register. You can then set the URL connection property to the endpoint of your Adobe Commerce system.
Administrator: To access Adobe Commerce as an administrator, set CustomAdminPath instead. This value can be obtained in the Advanced settings in the Admin menu, which can be accessed by selecting System -> Configuration -> Advanced -> Admin -> Admin Base URL.
If the Use Custom Admin Path setting on this page is set to YES, the value is inside the Custom Admin Path text box; otherwise, set the CustomAdminPath connection property to the default value, which is "admin".
You can then choose the Adobe Commerce entities you want to allow the API Server access to by clicking Settings -> Resources.
Additionally, click Settings -> Server and change the following settings for compatibility with PowerBuilder:
- Default Format: Select XML (Atom) in the menu.
- Default Version: Select 2.0 in the menu.
Authorize API Server Users
After determining the OData services you want to produce, authorize users by clicking Settings -> Users. The API Server uses authtoken-based authentication and supports the major authentication schemes. Access can also be restricted based on IP address; by default, only connections to the local machine are allowed. You can authenticate as well as encrypt connections with SSL.
Create a Profile for Adobe Commerce
Follow the steps below to use the Database Painter tool to create a database profile for the OData API of the API Server. In the Database Painter, you can graphically manipulate data as well as execute SQL queries.
- Click Tools -> Database Painter.
- Right-click the OData node and click New Profile.
- In the Database Profile Setup dialog, enter the following:
- Profile Name: Enter a user-friendly name for the profile.
- URI: Enter the URL to the OData endpoint of the API Server. This URL will resemble the one below:
http://MyServer:8032/api.rsc - Supply User Id and Password: Click this option to use HTTP Basic authentication. Note that the API Server also supports Windows authentication.
- User Id: Enter the name of an user in the API Server.
- Password: Enter the authtoken of an user in the API Server.
- To view and modify a table, right-click a table and then click Edit Data -> Grid.
Using Adobe Commerce Data with PowerBuilder Controls
You can use standard PowerBuilder objects to connect to OData feeds and execute queries. The following example shows how to retrieve Adobe Commerce data into a DataWindow.
You can add the following code to the open method:
SQLCA.DBMS = "ODT"
SQLCA.DBParm = "ConnectString='URI=http://MyServer:8032/api.rsc;UID=MyAPIUser;PWD=MyAuthtoken'";
CONNECT USING SQLCA;
dw_products.SetTransObject(SQLCA);
dw_products.Retrieve();
