Consume Sugar CRM OData Feeds in PowerBuilder



This article demonstrates how to consume Sugar CRM data as OData feeds from PowerBuilder using the API Server.

The CData API Server, when paired with the ADO.NET Provider for Sugar CRM (or any of 200+ other ADO.NET Providers), produces secure feeds of Sugar CRM 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 Sugar CRM 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 Sugar CRM

After you deploy the API Server and the ADO.NET Provider for Sugar CRM, provide authentication values and other connection properties needed to connect to Sugar CRM by clicking Settings -> Connections and adding a new connection in the API Server administration console.

The User and Password properties, under the Authentication section, must be set to valid SugarCRM user credentials. This will use the default OAuth token created to allow client logins. OAuthClientId and OAuthClientSecret are required if you do not wish to use the default OAuth token.

You can generate a new OAuth consumer key and consumer secret in Admin -> OAuth Keys. Set the OAuthClientId to the OAuth consumer key. Set the OAuthClientSecret to the consumer secret.

Additionally, specify the URL to the SugarCRM account.

Note that retrieving SugarCRM metadata can be expensive. It is advised that you store the metadata locally as described in the "Caching Metadata" chapter of the help documentation.

You can then choose the Sugar CRM 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 Sugar CRM

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.

  1. Click Tools -> Database Painter.
  2. Right-click the OData node and click New Profile.
  3. 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.
  4. To view and modify a table, right-click a table and then click Edit Data -> Grid.

Using Sugar CRM 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 Sugar CRM 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_accounts.SetTransObject(SQLCA); dw_accounts.Retrieve();
