Integrate Live Google Cloud Storage Data into Custom Business Apps Built in Power Apps

Power Apps is a service for building and using custom business apps that connect to your data and work across the web and mobile — without the time and expense of custom software development. When paired with CData Connect Server, you get instant access to Google Cloud Storage data from the apps you build using Power Apps. This article shows how to connect to Connect Server from Power Apps and build an app based on live Google Cloud Storage data.

CData Connect Server provides a pure SQL interface for Google Cloud Storage, allowing you to easily integrate with live Google Cloud Storage data in Power Apps — without replicating the data. CData Connect Server looks exactly like a SQL Server database to Power Apps and uses optimized data processing out of the box to push all supported SQL operations (filters, JOINs, etc) directly to Google Cloud Storage, leveraging server-side processing to quickly return Google Cloud Storage data.

Create a Virtual SQL Database for Google Cloud Storage Data

CData Connect Server uses a straightforward, point-and-click interface to connect to data sources and generate APIs.

1. Login to Connect Server and click Connections.
2. Select "Google Cloud Storage" from Available Data Sources.
3. Enter the necessary authentication properties to connect to Google Cloud Storage.

   Authenticate with a User Account

   You can connect without setting any connection properties for your user credentials. After setting InitiateOAuth to GETANDREFRESH, you are ready to connect.

   When you connect, the Google Cloud Storage OAuth endpoint opens in your default browser. Log in and grant permissions, then the OAuth process completes

   Authenticate with a Service Account

   Service accounts have silent authentication, without user authentication in the browser. You can also use a service account to delegate enterprise-wide access scopes.

   You need to create an OAuth application in this flow. See the Help documentation for more information. After setting the following connection properties, you are ready to connect:

   • InitiateOAuth: Set this to GETANDREFRESH.
   • OAuthJWTCertType: Set this to "PFXFILE".
   • OAuthJWTCert: Set this to the path to the .p12 file you generated.
   • OAuthJWTCertPassword: Set this to the password of the .p12 file.
   • OAuthJWTCertSubject: Set this to "*" to pick the first certificate in the certificate store.
   • OAuthJWTIssuer: In the service accounts section, click Manage Service Accounts and set this field to the email address displayed in the service account Id field.
   • OAuthJWTSubject: Set this to your enterprise Id if your subject type is set to "enterprise" or your app user Id if your subject type is set to "user".
   • ProjectId: Set this to the Id of the project you want to connect to.

   The OAuth flow for a service account then completes.

4. Click Save Changes
5. Click Privileges -> Add and add the new user (or an existing user) with the appropriate permissions.

Connecting to CData Connect Server

To use Connect Server to integrate Google Cloud Storage data into your Power Apps, you need a new SQL Server connection:

1. Log in to Power Apps
2. Click Data -> Connections -> New connection
3. Select SQL Server
4. In the connection wizard:
   
   
   • Choose to connect directly
   • Set SQL server name to the address of your Connect Server instance (CONNECT_SERVER_URL)
   • Set SQL database name to the name of the virtual Google Cloud Storage database you created earlier (like googlecloudstoragedb)
   • Set the Username and Password and click Create

Building a Data-Centric App for Google Cloud Storage Data

With the connection to Connect Server configured, you are ready to integrate live Google Cloud Storage data into the apps you build in Power Apps.

1. Log in to Power Apps
2. Click Create, hover over "Start from data" and click Make this app
3. Select the SQL Server connection you created
4. Search for or choose a table to work with
5. Click Connect
6. Customize the newly created app just like you would any other, including changing the layout and setting the fields exposed in BrowseScreen, DetailScreen, and EditScreen

At this point, you have an app with read access to live Google Cloud Storage data that you can save and publish for use within your organization.

SQL Access to Google Cloud Storage Data from Applications

Now you have a direct connection to live Google Cloud Storage data from Microsoft Power Apps. You can create more connections and apps to drive business — all without replicating Google Cloud Storage data.
