Integrate Alteryx and Power BI
Integrate Alteryx and Power BI

Learn how to make generic REST API request (bulk write) using the Power BI Connector for Alteryx. This connector enables you to read and write Microsoft Power BI data effortlessly. Access, refresh, and manage datasets, reports, and dashboards — almost no coding required. We'll walk you through the exact setup.

Let's dive in!

Create data source using Power BI ODBC Driver

  1. Download and install ODBC PowerPack (if you haven't already).

  2. Search for odbc and open the ODBC Data Sources (64-bit):

    Open ODBC Data Source
  3. Create a User data source (User DSN) based on the ZappySys API Driver driver:

    ZappySys API Driver
    Create new User DSN for ZappySys API Driver
    • Create and use a User DSN if the client application runs under a User Account. This is the ideal option at design time (e.g., when developing in Visual Studio). Use it for both types of applications (64-bit and 32-bit).
    • Create and use a System DSN if the client application runs under a System Account (e.g., as a Windows Service). This is usually the required option in a production environment. If your Windows Service is a 32-bit application, you must use the 32-bit ODBC Data Source Administrator to configure this
  4. When the Configuration window appears give your data source a name if you haven't done that already, then select "Power BI" from the list of Popular Connectors. If "Power BI" is not present in the list, then click "Search Online" and download it. Then set the path to the location where you downloaded it. Finally, click Continue >> to proceed with configuring the DSN:

    PowerBiDSN

    ODBC DSN Template Selection
  5. Now it's time to configure the Connection Manager. Select Authentication Type, e.g. Token Authentication. Then select API Base URL (in most cases, the default one is the right one). More info is available in the Authentication section.

    Power BI authentication

    Use delegated access (User Credentials) whenever you want to let a signed-in user work with their own resources or resources they can access. Whether it's an admin setting up policies for their entire organization or a user deleting an email in their inbox, all scenarios involving user actions should use delegated access. [API reference]

    Follow these simple steps below to create Microsoft Entra ID application with delegated access:

    WARNING: If you are planning to automate processes, we recommend that you use a Application Credentials authentication method. In case, you still need to use User Credentials, then make sure you use a system/generic account (e.g. automation@my-company.com). When you use a personal account which is tied to a specific employee profile and that employee leaves the company, the token may become invalid and any automated processes using that token will start to fail.
    1. Navigate to the Azure Portal and log in using your credentials.
    2. Access Microsoft Entra ID.
    3. Register a new application by going to App registrations and clicking on New registration button:

      Start new app registration in Microsoft Entra ID
      INFO: Find more information on how to register an application in Graph API reference.
    4. When configuration window opens, configure these fields:

      • Supported account type
        • Use Accounts in this organizational directory only, if you need access to data in your organization only.
      • Redirect URI:
        • Set the type to Public client/native (mobile & desktop).
        • Use https://zappysys.com/oauth as the URL.
      Register app in Microsoft Entra ID
    5. After registering the app, copy the Application (client) ID for later:

      Copy client ID of Microsoft Entra ID app
    6. Copy OAuth authorization endpoint (v2) & OAuth token endpoint (v2) URLs to use later in the configuration:

      Copy Auth and Token URLs in Microsoft Entra ID app
    7. Now go to SSIS package or ODBC data source and use the copied values in User Credentials authentication configuration:

      • In the Authorization URL field paste the OAuth authorization endpoint (v2) URL value you copied in the previous step.
      • In the Token URL field paste the OAuth token endpoint (v2) URL value you copied in the previous step.
      • In the Client ID field paste the Application (client) ID value you copied in the previous step.
      • In the Scope field use the default value or select individual scopes, e.g.:
        • offline_access
        • https://analysis.windows.net/powerbi/api/Workspace.Read.All
        • https://analysis.windows.net/powerbi/api/Dataset.Read.All
        • https://analysis.windows.net/powerbi/api/Dataset.ReadWrite.All
    8. Press Generate Token button to generate Access and Refresh Tokens.
    9. Click Test Connection to confirm the connection is working.
    10. Optional step. Choose Default Workspace from the drop down menu.
    11. Choose Default Dataset from the drop down menu.
    12. Done! Now you are ready to use the API Connector!
    API Connection Manager configuration

    Just perform these simple steps to finish authentication configuration:

    1. Set Authentication Type to User Credentials [OAuth]
    2. Optional step. Modify API Base URL if needed (in most cases default will work).
    3. Fill in all the required parameters and set optional parameters if needed.
    4. Press Generate Token button to generate the tokens.
    5. Finally, hit OK button:

    PowerBiDSN
    Open Query Builder in API ODBC Driver to read and write data to REST API
  8. Then simply select the Make Generic REST API Request (Bulk Write) endpoint (action).

  9. Continue by configuring the Required parameters. You can also set optional parameters too.

  10. Move on by hitting Preview Data button to preview the results.

  11. If you see the results you need, simply copy the generated query:

    SELECT * FROM __DynamicRequest__
    WITH
    (
        "Url" = '/something/123',
        "RequestMethod" = 'POST'
    )
    Query Builder
  12. Click OK to use built SQL query and close the Query Builder.

  13. Now hit Preview Data button to preview the data using the generated SQL query. If you are satisfied with the result, use this query in Alteryx:

    ZappySys API Driver - Power BI
    Read and write Microsoft Power BI data effortlessly. Access, refresh, and manage datasets, reports, and dashboards — almost no coding required.
    PowerBiDSN
    SELECT * FROM __DynamicRequest__
    WITH
    (
        "Url" = '/something/123',
        "RequestMethod" = 'POST'
    )
    API ODBC Driver-based data source data preview
    You can also access data quickly from the tables dropdown by selecting <Select table>.
    A WHERE clause, LIMIT keyword will be performed on the client side, meaning that the whole result set will be retrieved from the Power BI API first, and only then the filtering will be applied to the data. If possible, it is recommended to use parameters in Query Builder to filter the data on the server side (in Power BI servers).

Let's not stop here and explore SQL query examples, including how to use them in Stored Procedures and Views (virtual tables) in the next steps.

Power BI SQL query examples

Use these SQL queries in your Alteryx data source:

Make generic rest api request

SELECT * FROM __DynamicRequest__
WITH
(
    "Url" = '/something/123',
    "RequestMethod" = 'POST'
)

generic_request_bulk_write endpoint belongs to __DynamicRequest__ table(s), and can therefore be used via those table(s).

Create SQL view in ODBC data source

ZappySys API Drivers support flexible Query language so you can override Default Properties you configured on Data Source such as URL, Body. This way you don't have to create multiple Data Sources if you like to read data from multiple EndPoints. However not every application support supplying custom SQL to driver so you can only select Table from list returned from driver.

If you're dealing with Microsoft Access and need to import data from an SQL query, it's important to note that Access doesn't allow direct import of SQL queries. Instead, you can create custom objects (Virtual Tables) to handle the import process.

Many applications like MS Access, Informatica Designer wont give you option to specify custom SQL when you import Objects. In such case Virtual Table is very useful. You can create many Virtual Tables on the same Data Source (e.g. If you have 50 URLs with slight variations you can create virtual tables with just URL as Parameter setting.

  1. Go to Custom Objects Tab and Click on Add button and Select Add Table:
    ZappySys Driver - Add Table

  2. Enter the desired Table name and click on OK:
    ZappySys Driver - Add Table Name

  3. And it will open the New Query Window Click on Cancel to close that window and go to Custom Objects Tab.

  4. Select the created table, Select Text Type AS SQL and write the your desired SQL Query and Save it and it will create the custom table in the ZappySys Driver:
    Here is an example SQL query for ZappySys Driver. You can insert Placeholders also. Read more about placeholders here

    SELECT
      "ShipCountry",
      "OrderID",
      "CustomerID",
      "EmployeeID",
      "OrderDate",
      "RequiredDate",
      "ShippedDate",
      "ShipVia",
      "Freight",
      "ShipName",
      "ShipAddress",
      "ShipCity",
      "ShipRegion",
      "ShipPostalCode"
    FROM "Orders"
    Where "ShipCountry"='USA'

    ZappySys Driver - Create Custom Table
  5. That's it now go to Preview Tab and Execute your custom virtual table query. In this example it will extract the orders for the USA Shipping Country only:

    SELECT * FROM "vt__usa_orders_only"
    ZappySys Driver - Execute Custom Virtual Table Query

Make generic REST API request in Alteryx via SQL view

  1. Open Alteryx Designer.

  2. First, verify your DCM Settings to ensure you can access ODBC drivers. Go to Options > User Settings > Edit User Settings.

    If DCM Mode is set to DCM Only, change it to DCM Optional if you would like to access the legacy Generic ODBC Connection.

    Alteryx DCM User Settings for ODBC access
    After changing this setting, you may need to click Save and restart the connection window for the "Generic ODBC" icon to appear.
  3. Drag an Input Data tool onto your Alteryx canvas.

    Drag Input Data tool onto Alteryx canvas
  4. In the Configuration pane, click Set Up a Connection.

  5. Note for DCM Users: If your environment has DCM (Data Connection Manager) enabled, the classic "Generic ODBC" icon may be hidden. To find it, select Data sources on the left and type "ODBC" in the search bar.

  6. Once the ODBC window opens, click Connect Asset and select your PowerBiDSN DSN from the list.

    Connect Asset and select ODBC DSN in Alteryx
    Ensure you have configured a 64-bit System DSN in the Windows ODBC Data Source Administrator before this step.
  7. After selecting your DSN, configure your SQL Query in the Input Data tool configuration:

    Configure SQL Query in Alteryx Input Data tool
  8. To save your data, drag an Output Data tool and connect it to the Input Data tool.

  9. Configure the Output Data tool to write to a CSV file:

Creating SQL stored procedures

You can create procedures to encapsulate custom logic and then only pass handful parameters rather than long SQL to execute your API call.

Steps to create Custom Stored Procedure in ZappySys Driver. You can insert Placeholders anywhere inside Procedure Body. Read more about placeholders here

  1. Go to Custom Objects Tab and Click on Add button and Select Add Procedure:
    ZappySys Driver - Add Stored Procedure

  2. Enter the desired Procedure name and click on OK:
    ZappySys Driver - Add Stored Procedure Name

  3. Select the created Stored Procedure and write the your desired stored procedure and Save it and it will create the custom stored procedure in the ZappySys Driver. Here is an example stored procedure for ZappySys Driver. You can insert Placeholders anywhere inside Procedure Body. Read more about placeholders here

    CREATE PROCEDURE [usp_get_orders]
        @fromdate = '<<yyyy-MM-dd,FUN_TODAY>>'
     AS
        SELECT * FROM Orders where OrderDate >= '<@fromdate>';
    
    ZappySys Driver - Create Custom Stored Procedure
  4. That's it now go to Preview Tab and Execute your Stored Procedure using Exec Command. In this example it will extract the orders from the date 1996-01-01:

    Exec usp_get_orders '1996-01-01';
    ZappySys Driver - Execute Custom Stored Procedure
