Wijmo FlexGrid is a lightweight, high-performance JavaScript datagrid for creating responsive, interactive data applications.
With the CData API Server and the PingOne Connector (or any of the hundreds of 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 PingOne and display the data.
Let's get started!
Here's a quick overview of the steps we'll follow:
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:
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:
To connect to PingOne, configure these properties:
is the ID of the PingOne environment in which your Worker application resides. This parameter is used only when the environment is using the default PingOne domain (auth.pingone). It is configured after you have created the custom OAuth application you will use to authenticate to PingOne, as described in Creating a Custom OAuth Application in the Help documentation.
First, find the value for this property:
WorkerAppEnvironmentId='11e96fc7-aa4d-4a60-8196-9acf91424eca'
Now set to the value of the Environment ID field.
is the base URL of the PingOne authorization server for the environment where your application is located. This property is only used when you have set up a custom domain for the environment, as described in the PingOne platform API documentation. See Custom Domains.
PingOne supports both OAuth and OAuthClient authentication. In addition to performing the configuration steps described above, there are two more steps to complete to support OAuth or OAuthCliet authentication:
Set to OAuth.
Get and Refresh the OAuth Access Token
After setting the following, you are ready to connect:
When you connect, the driver opens PingOne's OAuth endpoint in your default browser. Log in and grant permissions to the application. The driver then completes the OAuth process:
The driver refreshes the access token automatically when it expires.
For other OAuth methods, including Web Applications, Headless Machines, or Client Credentials Grant, refer to the Help documentation.
To allow secure access to the created OData endpoints, create and configure Users in the API Server.
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.
👁 'Authtoken' Settings for the Added User in CData API ServerTo make data from PingOne accessible in Wijmo Grid via OData, you need to expose your desired tables through the API Server. Here's how:
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 PingOne 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.
You've got the CData API Server up and running now with consumable OData endpoints from your PingOne data. Now let's build a simple Wijmo FlexGrid that lets you select tables and columns and view your data.
