Create data source in ZappySys Data Gateway

In this section we will create a data source for Power BI in the Data Gateway. Let's follow these steps to accomplish that:

Download and install ODBC PowerPack (if you haven't already).
Search for gateway in the Windows Start Menu and open ZappySys Data Gateway Configuration:
Go to the Users tab and follow these steps to add a Data Gateway user:
- Click the Add button
- In the Login field enter a username, e.g., john
- Then enter a Password
- Check the Is Administrator checkbox
- Click OK to save
Now we are ready to add a data source:
- Click the Add button
- Give the Data source a name (have it handy for later)
- Then select Native - ZappySys API Driver
- Finally, click OK
PowerBiDSN

ZappySys API Driver
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:

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.

User Credentials

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.

Navigate to the Azure Portal and log in using your credentials.
Access Microsoft Entra ID.
Register a new application by going to App registrations and clicking on New registration button:

INFO: Find more information on how to register an application in Graph API reference.
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.
After registering the app, copy the Application (client) ID for later:
Copy OAuth authorization endpoint (v2) & OAuth token endpoint (v2) URLs to use later in the configuration:
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
Press Generate Token button to generate Access and Refresh Tokens.
Click Test Connection to confirm the connection is working.
Optional step. Choose Default Workspace from the drop down menu.
Choose Default Dataset from the drop down menu.
Done! Now you are ready to use the API Connector!

API Connection Manager configuration

Just perform these simple steps to finish authentication configuration:

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

Once the data source connection has been configured, it's time to configure the SQL query. Select the Preview tab and then click Query Builder button to configure the SQL query:

Read and write Microsoft Power BI data effortlessly. Access, refresh, and manage datasets, reports, and dashboards — almost no coding required.

PowerBiDSN
Start by selecting the Table or Endpoint you are interested in and then configure the parameters. This will generate a query that we will use in Java to retrieve data from Power BI. Hit OK button to use this query in the next step.
```
SELECT * 
FROM Workspaces
WHERE Id='aaaaaaaa-bbbb-cccc-dddd-eeeeeeeeeeee'
```
Some parameters configured in this window will be passed to the Power BI API, e.g. filtering parameters. It means that filtering will be done on the server side (instead of the client side), enabling you to get only the meaningful data much faster.
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 Java:

PowerBiDSN
```
SELECT * 
FROM Workspaces
WHERE Id='aaaaaaaa-bbbb-cccc-dddd-eeeeeeeeeeee'
```
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).
Click OK to finish creating the data source.
Once done, go to the Network Settings tab and Add a firewall rule for inbound traffic:
- This will initially allow all inbound traffic.
- Click Edit IP filters to restrict access to specific IP addresses or ranges.
Crucial Step: After creating or modifying the data source, you must:
- Click the Save button to persist your changes.
- Hit Yes when prompted to restart the Data Gateway service.
This ensures all changes are properly applied:

Skipping this step may cause the new settings to fail, preventing you from connecting to the data source.

Read data in Java from the DSN

Java code to get the data:

"jdbc:sqlserver://localhost:5000;databasename=PowerBiDSN;user=john;password=test"
When you run the code it will make the API call and read the data:

Here is Java program's code in text format:

        // Declare the JDBC objects.
        Connection con = null;
        Statement stmt = null;
        ResultSet rs = null;

            try {

                Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
                con = DriverManager.getConnection(connectionUrl);

                // Create and execute an SQL statement that returns some data.
                String SQL = "SELECT Country , SUM(UnitPrice * Quantity) Total " 
                           + "FROM value " 
                           + "GROUP BY Country "
                           + "WITH (SRC='https://services.odata.org/V3/Northwind/Northwind.svc/Invoices?$format=json')";
                stmt = con.createStatement();
                rs = stmt.executeQuery(SQL);

                // Iterate through the data in the result set and display it.
                while (rs.next()) {
                    System.out.println(rs.getString(1) + " " + rs.getString(2));
                }
            }

        // Handle any errors that may have occurred.
        catch (Exception e) {
            e.printStackTrace();
        } 
        
        finally {
            if (rs != null) try { rs.close(); } catch (Exception e) {}
            if (stmt != null) try { stmt.close(); } catch (Exception e) {}
            if (con != null) try { con.close(); } catch (Exception e) {}
        }
    }
}
