Import Backlog Data into Microsoft Power Query

The Connect Server enables you to use Web services to connect to and query Backlog data. This article details how to import an OData feed of Backlog data into Microsoft Power Query.

Connect to Backlog from Power Query

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

Add a Connect Server User

Create a User to connect to Backlog from Microsoft Power Query 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 Backlog 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 "Backlog" from Available Data Sources
3. Enter the necessary authentication properties to connect to Backlog.

   In order to authenticate using the API Key, specify the following:

   • AuthScheme: Set to APIToken.
   • API Key: Set to the API Key that allows you to make requests to the Backlog API. You can generate this key by opening the Settings page in Backlog and selecting the API section.
   • URL: Set to the your Backlog tenant URL.

   In order to authenticate using OAuth, set AuthScheme to "OAuth" and refer to the Help 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 Backlog OData Endpoints in Connect Server

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

1. Click OData -> Tables -> Add Tables
2. Select the Backlog 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 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.

Connect to Backlog Data from Power Query

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

1. Configure the Connect Server to use a version of the OData protocol that is recognized by Power Query. In the Connect Server administration console, click Settings -> Server and change the value of the Default Version property to 3.0.

2. From the ribbon in Excel, click Power Query -> From Other Data Sources -> From OData Feed, and enter the OData URL:

   https://your-server:8032/api.rsc

3. Next, define authentication credentials and set privacy levels. Select Basic authentication and enter the credentials for a user authorized to make requests. Specify the Username field and enter the user's authtoken in the Password field.

   To change the authentication scheme that Power Query will use, click Power Query -> Data Source Settings. Select the OData feed from the list and then click "Edit Permissions..." Select the privacy level from the menu.

4. You can now access Backlog data in Power Query. In the Navigator expand the node for the OData feed, right-click a table, and click Edit to open the Query Editor. This will display the table data.
