Bind Live Sage 50 UK Data in Wijmo FlexGrid with CData API Server

With CData API Server, easily create OData endpoints for live Sage 50 UK data and seamlessly connect and bind them to Wijmo's FlexGrid for real-time, interactive data access without manual data movement.

Wijmo FlexGrid is a lightweight, high-performance JavaScript datagrid for creating responsive, interactive data applications.

With the CData API Server and the Sage 50 UK Connector (or any of the 350+ available connectors), you can quickly create APIs that expose live data from multiple sources, using industry standards like OData and Swagger for seamless integration with client-side and server-side controls in Wijmo's FlexGrid.

In this article, we'll use the Wijmo FlexGrid JavaScript components to build a simple HTML page that lets you select tables and columns from Sage 50 UK and display the data.

Let's get started!

Prerequisites

CData API Server: Download a free trial here.
Wijmo FlexGrid: No downloads are required for this example, but you can sign up for a free trial here.
An active Sage 50 UK account with access to your data.

Overview

Here's a quick overview of the steps we'll follow:

Install the CData API Server, configure a connection to Sage 50 UK, and expose OData endpoints.
Bind Wijmo Grid to the live OData feed for real-time data access and interaction.

Step 1: Install the CData API Server and Add a Connection to Sage 50 UK

1.1 Install the API Server

If you haven't already, download an installer for your machine from the CData API Server page. Follow the installation instructions to complete the setup.

Once installed, you can start the server in the following ways:

Windows: CData API Server runs as a service by default. Make sure the service is running, then open http://hostname:port (e.g., http://localhost:8080/) in your browser to access the API Server admin console.
Linux/Mac: You can run the server manually or as a service. To start it manually, navigate to the installation directory and run java -jar apiserver.jar.
Alternatively, run service.sh with root privileges to set up API Server as a Linux system service.

1.2 Enable CORS

When your Wijmo Grid application and the CData API Server are hosted on different domains, CORS (Cross-Origin Resource Sharing) must be enabled. To enable CORS in the API Server:

Go to Settings and click the icon to edit CORS settings.
Enable Cross-Origin Resource Sharing (CORS).
Enable Allow all domains without '*' to accept any origin.
In Access-Control-Allow-Origin, enter your Sage 50 UK origin domain, or use * to allow all domains (suitable for public APIs).
Enable Access-Control-Allow-Credentials to allow cookies and auth headers.
In Access-Control-Allow-Methods, enter GET, PUT, POST, OPTIONS.
In Access-Control-Allow-Headers, enter Authorization, Content-Type.
Set Access-Control-Max-Age (default: 3600 seconds).
Click Save.

Enabling CORS Settings in the CData API Server

1.3 Add a Sage 50 UK Connection in the API Server

Go to Settings and click Add Connection in the top-right.
Select Sage 50 UK. If it's not visible, toggle off Only Installed to view all connectors.
Click Install Connector to auto-install. For a manual setup, choose Manual Install and upload the obtained ZIP file.
Once installed, click Sage 50 UK to configure connection settings.

Note: Only Sage 50 UK 2012 and above are supported.

The User and Password properties, under the Connection section, must be set to valid Sage 50 UK user credentials. These values will be the same used to log in to the Sage 50 UK software.

Additionally, the URL property, under the Connection section, will need to be set to the address of the company dataset desired. To obtain the address, do the following:

If you have not already done so, open the Sage 50 UK software.
Click Tools -> Internet Options.
Select the SData Settings tab.
Click the Details button next to Sage 50 Accounts. A window is displayed containing a list of company names along with the address to their corresponding datasets.
Set the URL property to the value in the address field next to the company desired.

Click Save & Test to validate and complete the connection setup.

Adding a Connection in the CData API Server

1.4 Add and Configure Users

To allow secure access to the created OData endpoints, create and configure Users in the API Server.

Go to Users from the navigation pane, then click Add User.
Set a Username and Password.
Select a Role: Select Admin for full access and Query for limited access.
Define user Privileges (GET, POST, PUT, DELETE, etc.).
Click Add User to save.

Once a user is added, an Authtoken is automatically generated. This token can be used in API requests as a secure authentication method instead of a password.

You can also refresh the Authtoken, disable it, or set expiration rules (e.g., number of days until expiry) by enabling the Token Expiration option in the user settings.

1.5 Add Tables for the Endpoint

To make data from Sage 50 UK accessible in Wijmo Grid via OData, you need to expose your desired tables through the API Server. Here's how:

In the API Server, go to API and click Add Table.
Select the Sage 50 UK connection and click Next.
Choose the tables you want to expose and click Confirm.

Adding Tables for API Endpoint in CData API Server

1.6 Access the Endpoints in Wijmo FlexGrid

Now that your API is configured, Wijmo FlexGrid can connect to the OData endpoints to display live data. Below are the URL formats for OData endpoints that you can use:

Endpoint		URL
Entity List		http://`address`:`port`/api.rsc/
Table Metadata (e.g., albums)		http://`address`:`port`/api.rsc/albums/$metadata?@json
Table Data (e.g., albums)		http://`address`:`port`/api.rsc/albums

These OData endpoints are now ready to be directly consumed in Wijmo FlexGrid using the URL. Since Wijmo FlexGrid supports OData, you can easily bind live data from Sage 50 UK and create dynamic, interactive grids.

The CData API Server supports full OData filtering capabilities. For custom queries and filtered visualizations, you can append standard OData query parameters like $select, $filter, $orderby, $top, and $skip to your requests.

Step 2: Build the Simple Wijmo Grid

You've got the CData API Server up and running now with consumable OData endpoints from your Sage 50 UK data. Now let's build a simple Wijmo FlexGrid that lets you select tables and columns and view your data.

Get the CData API Endpoint URL by logging into your CData API Server. Go to API from the left navigation, then click View Endpoints at the top-right.
Copy the URL (e.g., http://localhost:8080/api.rsc).

Getting the API Endpoint URL from CData API Server

Create a new HTML file and give it a name (e.g., Wijmo-Grid.html).
Paste the following code into your HTML file.
Update the following placeholder values at the start of the script section:

yourUsername: Replace with your CData API Server username.
yourPassword: Replace with your CData API Server password.
Your_CData_API_Server_URL: Replace with the full API endpoint URL you copied earlier.
