Use the Connect Server to Access eBay Data in Microsoft Power Pivot

This article will explain how to use the Connect Server to provide eBay data as OData services and then consume the data in Microsoft Excel's Power Pivot business intelligence tool. Follow the steps below to retrieve and edit eBay data in Power Pivot.

Connect to eBay from Power Pivot

To work with live eBay data in Power Pivot, we need to connect to eBay from Connect Server, provide user access to the new virtual database, and create OData endpoints for the eBay data.

Add a Connect Server User

Create a User to connect to eBay from Power Pivot 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 Endpoints 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 domains from an application, 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.

Import eBay Tables in Power Pivot

Follow the steps below to import tables that can be refreshed on demand:

1. In Excel, click Data -> Get Data -> From Other Sources -> From OData Feed
2. Fill out the OData feed URL (e.g. http://localhost:8080/odata.rsc)
3. On the next screen, select Basic and configure the username and password. Password should be your auth token.

4. Select the tables that you would like to import into Excel

5. After selecting your table(s) and clicking Load, you should see the data appear in an Excel spreadsheet

6. Now, click the Power Pivot tab on the ribbon, and then select Add to Data Model. This can now work with your eBay data in Power Pivot.
