Consume Epicor Kinetic OData Feeds in PowerBuilder
This article demonstrates how to consume Epicor Kinetic data as OData feeds from PowerBuilder using the API Server.
The CData API Server produces secure feeds of Epicor Kinetic 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 Epicor Kinetic 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 Epicor Kinetic
After you deploy the API Server, provide authentication values and other connection properties needed to connect to Epicor Kinetic by clicking Settings -> Connections and adding a new connection in the API Server administration console.
To successfully connect to your ERP instance, you must specify the following connection properties:
- Url:the URL of the server hosting your ERP instance. For example, https://myserver.EpicorSaaS.com
- ERPInstance: the name of your ERP instance.
- User: the username of your account.
- Password: the password of your account.
- Service: the service you want to retrieve data from. For example, BaqSvc.
In addition, you may also set the optional connection properties:
- ApiKey: An optional key that may be required for connection to some services depending on your account configuration.
- ApiVersion: Defaults to v1. May be set to v2 to use the newer Epicor API.
- Company: Required if you set the ApiVersion to v2.
You can then choose the Epicor Kinetic 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 Epicor Kinetic
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 Epicor Kinetic 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 Epicor Kinetic 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_customers.SetTransObject(SQLCA);
dw_customers.Retrieve();
