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

This article will explain how to use the Connect Server to provide TaxJar 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 TaxJar data in Power Pivot.

Connect to TaxJar from Power Pivot

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

Add a Connect Server User

Create a User to connect to TaxJar 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 TaxJar 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 "TaxJar" from Available Data Sources
3. Enter the necessary authentication properties to connect to TaxJar.

   To authenticate to the TaxJar API, you will need to first obtain the API Key from the TaxJar UI.

   NOTE: the API is available only for Professional and Premium TaxJar plans.

   If you already have a Professional or Premium plan you can find the API Key by logging in the TaxJar UI and navigating to Account -> TaxJar API. After obtaining the API Key, you can set it in the APIKey connection property.

   Additional Notes

   • By default, the CData connector will retrieve data of the last 3 months in cases where the entity support date range filtering. You can set StartDate to specify the minimum creation date of the data retrieved.
   • If the API Key has been created for a sandbox API account please set UseSandbox to true, but not all endpoints will work as expected. For more information, refer to the TaxJar developer documentation.
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 TaxJar OData Endpoints in Connect Server

After connecting to TaxJar, create OData Endpoints for the desired table(s).

1. Click OData -> Tables -> Add Tables
2. Select the TaxJar 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 TaxJar 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 TaxJar data in Power Pivot.
