How to read Power BI data in ZappySys Data Gateway?

In this section we will learn how to configure and use Power BI Connector in the API Driver to extract data from the Power BI.

Create Data Source in ZappySys Data Gateway based on ZappySys API Driver

Download and install ZappySys ODBC PowerPack.
Search for gateway in start menu and Open ZappySys Data Gateway:
Go to Users Tab to add our first Gateway user. Click Add; we will give it a name tdsuser and enter password you like to give. Check Admin option and click OK to save. We will use these details later when we create linked server:
Now we are ready to add a data source. Click Add, give data source a name (Copy this name somewhere, we will need it later) and then select Native - ZappySys API Driver. Finally, click OK. And it will create the Data Set for it and open the ZS driver UI.

PowerBiDSN
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 [OAuth]

OAuth App must be created in Microsoft Azure AD. These settings typically found here https://docs.microsoft.com/en-us/graph/auth-register-app-v2. [API Help..]

Steps to get Power BI Credentials : User Credentials [OAuth]

Firstly, login into Azure Portal and there create an OAuth application:

Go to Azure Portal and login there.
Then go to Azure Active Directory.
On the left side click menu item App registrations
Then proceed with clicking New registration.
Enter a name for your application.
Select the account types to support with the Supported account types option.
In Redirect URI, select Web.
In the textbox enter https://zappysys.com/oauth as the Redirect URI or another valid redirect URL.
Use this same Redirect URI in the Redirect URI (must match App Redirect URL) grid row.
Copy Client ID and paste it into the API Connection Manager configuration grid in the Client ID row.
Click on the Endpoints link and copy the OAuth 2.0 authorization endpoint (v2) URL to the Authorization URL grid row. Usually it looks similar to this:
- https://login.microsoftonline.com/daed1250-xxxx-xxxx-xxxx-ef0a982d3d1e/oauth2/v2.0/authorize
Copy the OAuth 2.0 token endpoint (v2) URL to the Token URL grid row. Usually it looks similar to this:
- https://login.microsoftonline.com/daed1250-xxxx-xxxx-xxxx-ef0a982d3d1e/oauth2/v2.0/token
Close "Endpoints" popup and create a Client Secret in the Certificates & secrets tab.
Proceed by clicking New client secret and setting expiration period. Copy the client secret and paste it into configuration grid in Client Secret row.
Now lets setup permissions for the app. Click on API Permissions and on the page click Plus Sign Add Permission
Click on Microsoft Graph API and then choose Delegated Permissions
on Permission list page search or choose permissions as needed. We need to enable following Permissions from 2 Sections: Microsoft Graph API and Power BI Service.
Make sure you have checked below permissions (If you do not need Write feature then you can skip Write scopes)
```
offline_access
Dataset.ReadWrite.All
```
Click Generate Token to generate tokens.
That's it!

Fill in all required parameters and set optional parameters if needed:

Once the data source has been configured, you can preview data. Select the Preview tab and use settings similar to the following to preview data:
Click OK to finish creating the data source.

Reading data from client application

Firstly, to get data from ODBC data source based on ZappySys ODBC driver, in your client application, you would need to connect to ODBC source and then from the list select the data source.
Finally, to read the data just read tables/views in your app or enter a SQL statement to extract data, e.g.:
SELECT * FROM Datasets
