Analyze eBay Data in Infragistics Reveal

Reveal is a data visualization solution provided by Infragistics and can be paired with the CData Connect Server and eBay Connector to build dynamic dashboards from live eBay data. The CData Connect Server creates a virtual database for eBay and can be used to generate an OData API (natively consumable in Reveal) for eBay. In this article, we walk through connecting to eBay in Connect Server and connecting to Connect Server from Infragistics Reveal to create a simple dashboard.

Add a Connect Server User

Create a User to connect to eBay from Reveal through Connect Server.

1. Click Users -> Add
2. Configure a User
3. Click Save Changes and make note of the Authtoken for the new user

Connect to eBay from Connect Server

CData Connect Server uses a straightforward, point-and-click interface to connect to data sources and generate APIs.

1. Open Connect Server and click Connections
2. Select "eBay" from Available Data Sources
3. Enter the necessary authentication properties to connect to eBay.

   If you will be accessing your own account, you can generate an OAuthAccessToken from your developer account dashboard. You can also allow other users to securely access their own accounts.

   Both of these methods require you to create an application key set to obtain values for the following connection properties: AppId, CertId, DevId, and SiteId.

   The user consent flow additionally requires the RuName and CallbackURL.

   See the "Getting Started" chapter in the help documentation for a guide to using OAuth.

4. Click Save Changes
5. Click Privileges -> Add and add the new user (or an existing user) with the appropriate permissions (SELECT is all that is required for Reveal).

Add eBay OData Endpoints in Connect Server

After connecting to eBay, create OData Endpoint for the desired table(s).

1. Click OData -> Tables -> Add Tables
2. Select the eBay database
3. Select the table(s) you wish to work with and click Next
4. (Optional) Edit the resource to select specific fields and more
5. Save the settings

(Optional) Configure Cross-Origin Resource Sharing (CORS)

When accessing and connecting to multiple different domains from an application such as Ajax, there is a possibility of violating the limitations of cross-site scripting. In that case, configure the CORS settings in OData -> Settings.

• Enable cross-origin resource sharing (CORS): ON
• Allow all domains without '*': ON
• Access-Control-Allow-Methods: GET, PUT, POST, OPTIONS
• Access-Control-Allow-Headers: Authorization

Save the changes to the settings.

Create a Dashboard in Reveal

With Connect Server configured, we can visualize eBay data in Reveal.

1. Log into Reveal and click Dashboards -> New
2. Click Data Source -> OData Feed
3. Specify the Connect Server API endpoint URL (found in API -> Discovery -> Base URL), for example: CONNECT_SERVER_URL/api.rsc
4. Select Generic Credentials and specify the Connect Server username and authentication token
5. Select the entity you wish to visualize
6. Select fields and choose a chart type
