OneDrive Connector for C# OneDrive Connector can be used to integrate OneDrive and your defined data source, e.g. Microsoft SQL, Oracle, Excel, Power BI, etc. Get, write, delete OneDrive data in a few clicks! In this article you will learn how to quickly and efficiently integrate OneDrive data in C#. We will use high-performance OneDrive Connector to easily connect to OneDrive and then access the data inside C#. Let's follow the steps below to see how we can accomplish that! Download Documentation OneDrive Connector for C# is based on ZappySys API Driver which is part of ODBC PowerPack. It is a collection of high-performance ODBC drivers that enable you to integrate data in SQL Server, SSIS, a programming language, or any other ODBC-compatible application. ODBC PowerPack supports various file formats, sources and destinations, including REST/SOAP API, SFTP/FTP, storage services, and plain files, to mention a few.

Create ODBC Data Source (DSN) based on ZappySys API Driver

Step-by-step instructions

To get data from OneDrive using C# we first need to create a DSN (Data Source) which will access data from OneDrive. We will later be able to read data using C#. Perform these steps:

1. Download and install ODBC PowerPack.

2. Open ODBC Data Sources (x64):

   

3. Create a User data source (User DSN) based on ZappySys API Driver

   ZappySys API Driver

   
   • Create and use User DSN if the client application is run under a User Account. This is an ideal option in design-time, when developing a solution, e.g. in Visual Studio 2019. Use it for both type of applications - 64-bit and 32-bit.
   • Create and use System DSN if the client application is launched under a System Account, e.g. as a Windows Service. Usually, this is an ideal option to use in a production environment. Use ODBC Data Source Administrator (32-bit), instead of 64-bit version, if Windows Service is a 32-bit application.

4. When the Configuration window appears give your data source a name if you haven't done that already, then select "OneDrive" from the list of Popular Connectors. If "OneDrive" 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:

   OnedriveDSN

   OneDrive

   

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.

    User Credentials [OAuth]

   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]

   Steps how to get and use OneDrive credentials
   

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

   WARNING: To automate your company's processes, 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:
      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.
      
   5. After registering the app, copy the Application (client) ID for later:
   6. Then copy OAuth authorization endpoint (v2) & OAuth token endpoint (v2) URLs to use later in the configuration:
   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.:
        • email
        • offline_access
        • openid
        • profile
        • User.Read
        • Files.Read.All
        • Files.ReadWrite.All
   8. Press Generate Token button to generate Access and Refresh Tokens.
   9. Optional step. Choose Default Site Id from the drop down menu.
   10. Click Test Connection to confirm the connection is working.
   11. Done! Now you are ready to use the API Connector!

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

    Application Credentials [OAuth]

   Application-only access is broader and more powerful than delegated access (User Credentials), so you should only use app-only access where needed. Use it when: 1. The application needs to run in an automated way, without user input (for example, a daily script that checks emails from certain contacts and sends automated responses). 2. The application needs to access resources belonging to multiple different users (for example, a backup or data loss prevention app might need to retrieve messages from many different chat channels, each with different participants). 3. You find yourself tempted to store credentials locally and allow the app to sign in 'as' the user or admin. [API reference]

   Steps how to get and use OneDrive credentials
   

   Follow these simple steps below to create Microsoft Entra ID application with application access permissions. Using following steps, you can grant very granular app permissions to access Full site(s), List(s), List Item(s) and File(s). Choose permission based on your need.

   Create OAuth app

   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:
      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
        • e.g. select 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).
        • Leave the URL field empty.
      
   5. After registering the app, copy the Application (client) ID for later:
   6. Then copy OAuth authorization endpoint (v2) & OAuth token endpoint (v2) URLs:
   7. Continue and create Client secret:
   8. Then copy the Client secret for later steps:
   9. Continue by adding permissions for the app by going to the API permissions section, and clicking on Add a permission:
   10. Select Microsoft Graph:
   11. Then choose Application permissions option:
   12. Continue by adding these Files (OneDrive) permissions (Just search for "Site" and then select desired permissions):
   13. Move on by addding these Sites (SharePoint) permissions (You can search for "Site" and then select desired permissions):
   14. Finish by clicking Add permissions button:
   15. Now it's time to Grant admin consent for your application:
   16. Confirm all the permissions are granted:
   17. Now go to SSIS package or ODBC data source and use the copied values in Application Credentials authentication configuration:
       • 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 Client Secret field paste the Client secret value you copied in the previous step.
       • Optional step. Choose Default Site Id from the drop down menu.
   18. Click Test Connection to confirm the connection is working.
   19. Done! Let's move on to the next step.

   Step-2 (Method#1 - New Approach): Grant permission to app using permission API (UI is not available yet)

   In year 2024 microsoft launched

   *.Selected

   permission scopes and new APIs to grant granular permissions to the resource for app access scenario. Unfortunatly, there is no User interface available yet to control this access so you have to call Admin API or use PowerShell script to control this. [Click here to learn more]. Follow these simple steps to configure permissions for app we created earlier (steps assume you are the owner of the resource and like to grant some permissions e.g. read, write, full, owner):

   1. Open PowerShell (Run as Admin user)
   2. Install Graph API module by running this command

      Import-Module Microsoft.Graph.Sites

   3. Now you can call following PowerShell code to set "read" and "write" permission for the app we created earlier (assuming app id is 89ea5c94-7736-4e25-95ad-3fa95f62b66e).

      
      #More info https://learn.microsoft.com/en-us/graph/permissions-selected-overview?tabs=powershell
      
      #Step-1: Install module if not found
      #Install-Module Microsoft.Graph.Sites
      
      #Step-2: set permission for app 89xxx6e and site zappysys.xx.efcdd21xxxxe2
      Import-Module Microsoft.Graph.Sites
      
      #Step-3: Login
      Connect-MgGraph
      
      #Step-4: Set Parameters for API Call (set Permissions, SiteId and AppId - Replace under #TODO)
      
      You can find SiteId by visiting this URL in browser (assuming you visted SharePoint site and already logged in) https://{your-company}.sharepoint.com/_api/site --OR-- for sub-site use https://{your-company}.sharepoint.com/sites/{your-site}/_api/site. Find  Id from the response (e.g. <Id m:type="Edm.Guid">)
      $siteId="yourcompany.sharepoint.com,efcddxxxxxxx104d8b5e3,8c9c6xxxxxxxx84e2"
      #--OR-- simple id
      #$siteId="efcddxxxxxxx104d8b5e3"
      
      
      $params = @{
      	roles = @(
              #possible options are read, write, fullcontrol, owner (write includes read too)
      		#TODO: Change here
      		"write"
      	)
      	grantedTo = @{
      		application = @{
                  #find this Client Id (Application Id) from the Azure Portal - Application page (https://portal.azure.com/#view/Microsoft_AAD_RegisteredApps/ApplicationsListBlade)
      			#TODO: Change here
      			id = "c3e9xxxxxx-xxxxx-xxxxx-xxxx-xxxxxb30c1"
      		}
      	}
      }

    Application Credentials with Certificate (Sign JWT with Private Key) [OAuth]

   Steps how to get and use OneDrive credentials
   To use Certificate-Based Authentication Setup please follow the steps listed in [Application Credentials] authentication and once done come back here to finish next stsps.

   This guide walks you through setting up a certificate-based authentication flow for Microsoft Graph or other Azure AD protected APIs using client credentials and a JWT.

   Step 1: Generate a Self-Signed Certificate

   You can use OpenSSL or any other way to generate Certificate file but make it simple below example uses PowerShell. Open PowerShell and execute code listed in below steps.

   
   # Run this in PowerShell
   #Change .AddYears(1) to desired number. By default it expires certificate in one year as per below code.
   
   $cert = New-SelfSignedCertificate `
     -Subject "CN=MyClientAppCert" `
     -KeySpec Signature `
     -KeyExportPolicy Exportable `
     -KeyLength 2048 `
     -CertStoreLocation "Cert:\CurrentUser\My" `
     -KeyAlgorithm RSA `
     -HashAlgorithm SHA256 `
     -NotAfter (Get-Date).AddYears(1) `
     -Provider "Microsoft Enhanced RSA and AES Cryptographic Provider"
   
   # Export private key (.pfx)  - Keep this with you to make API calls (SECRET KEY - DONOT SHARE)
   $pfxPath = "$env:USERPROFILE\Desktop\private_key.pfx"
   $pwd = ConvertTo-SecureString -String "yourStrongPassword123" -Force -AsPlainText
   Export-PfxCertificate -Cert $cert -FilePath $pfxPath -Password $pwd
   
   # Export public certificate (.cer) - UPLOAD this to Azure Portal
   $cerPath = "$env:USERPROFILE\Desktop\public_key.cer"
   Export-Certificate -Cert $cert -FilePath $cerPath
   

   Step 2: Register or Configure an App in Azure AD

   1. Go to https://portal.azure.com
   2. Navigate to Azure Active Directory > App registrations
   3. Click + New registration or open an existing app
   4. Copy the Application (client) ID and Directory (tenant) ID

   Step 3: Upload the Certificate

   1. In your App Registration, go to Certificates & secrets
   2. Under Certificates, click Upload certificate
   3. Select the .cer file (public certificate)
   4. Click Add

   Step 4: Grant API Permissions

   1. Go to the API permissions tab
   2. Click Add a permission
   3. Select Microsoft Graph (or another API)
   4. Choose Application permissions
   5. Add scopes such as:
      • Sites.Read.All
      • Sites.ReadWrite.All
      • Files.Read.All
      • Files.ReadWrite.All
      • email
      • offline_access
      • openid
      • profile
      • User.Read
   6. Click Grant admin consent (requires admin)

   Step 5: Use PFX file

   Once both files generated perform the following steps to use PFX file., , Use the Certificate file (*.pfx) Now its time to use pfx file generated in the previous step. PFX file contains private key and public key both.

   1. On ZappySys Connection UI Go to Certificate Tab
   2. Change Storage Mode to Local PFX File (or you can Import PFX file in Certificate Storage - User Store / Machine Store and use that way)
   3. Supply the pfx file path or select certificate from Local Certificate Store if you imported that way in earlier step
   4. Supply the certificate password (same password used in earlier PowerShell script)
   5. Test connection see everything is good

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

   OnedriveDSN

   OneDrive

   Application Credentials with Certificate (Sign JWT with Private Key) [OAuth]

   https://graph.microsoft.com/v1.0

   Required Parameters
   Token URL	Fill-in the parameter...
   Client ID	Fill-in the parameter...
   Certificate: *** Configure [Client Certificate] Tab ***	Fill-in the parameter...
   Default Site Id	Fill-in the parameter...
   Optional Parameters

   RetryMultiplyWaitTime	True
   Search Option For Non-Indexed Fields (Default=Blank - Search Only Indexed)
   Extra Headers (e.g. Header1:AAA||Header2:BBB)
   IsAppCred	1

   

6. 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:

   

   ZappySys API Driver - OneDrive

   OneDrive Connector can be used to integrate OneDrive and your defined data source, e.g. Microsoft SQL, Oracle, Excel, Power BI, etc. Get, write, delete OneDrive data in a few clicks!

   OnedriveDSN

   

7. 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 C# to retrieve data from OneDrive. Hit OK button to use this query in the next step.

   SELECT * FROM Files

   
   Some parameters configured in this window will be passed to the OneDrive 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.

8. 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 C#:

   

   ZappySys API Driver - OneDrive

   OneDrive Connector can be used to integrate OneDrive and your defined data source, e.g. Microsoft SQL, Oracle, Excel, Power BI, etc. Get, write, delete OneDrive data in a few clicks!

   OnedriveDSN

   SELECT * FROM Files

   
   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 OneDrive 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 OneDrive servers).

9. Click OK to finish creating the data source.

Read data in C#

Using ODBC DSN

1. Create a new Console project and use this code to read the data:
   

   "OnedriveDSN";

   

2. Press F5 to run the code and read the data:
   

3. Here is the code in text format:

   using System;
   using System.Data.Odbc;
   
   namespace ConsoleApp {
       class Program {
           static void Main() {
               var dsn = "OnedriveDSN";
               using (var conn = new OdbcConnection(String.Format("DSN={0}", dsn)))
               {
                   conn.Open();
                   var cmd = new OdbcCommand("SELECT * FROM Products", conn);
                   
                   //Increase the timeout duration from the default 30 seconds, which may be insufficient in certain scenarios
                   cmd.CommandTimeout=600; // 600-Seconds
                   
                   var rdr = cmd.ExecuteReader();
                   while (rdr.Read())
                   {
                       for (int i = 0; i < rdr.FieldCount; i++)
                       {
                               Console.Write("{0}\t", rdr[i]);
                       }
                       Console.WriteLine();
                   }
               }
               Console.ReadKey();
           }
       }
   }
   

Using a full ODBC connection string

If you want to avoid being dependent on a DSN and creating multiple DSNs for each platform (x86, x64), then you can use a fully qualified connection string. Simply go to your DSN and copy the Connection String:

1. Open ODBC data source configuration and click Copy settings:
   

   ZappySys API Driver - OneDrive

   OneDrive Connector can be used to integrate OneDrive and your defined data source, e.g. Microsoft SQL, Oracle, Excel, Power BI, etc. Get, write, delete OneDrive data in a few clicks!

   OnedriveDSN

   
2. The window opens, telling us the connection string was successfully copied to the clipboard:

3. Then in your C# code, pass the connection string as an argument when calling the OdbcConnection object's constructor, for example:

   var connectionString = @"DRIVER={ZappySys API Driver};ServiceUrl=https://graph.microsoft.com/v1.0;Provider=Custom;OAuthVersion=OAuth2;ScopeSeparator={space};GrantType=Default;Scope=[$Scope$];ScopeSeparator={space};";
   
   using (var conn = new OdbcConnection(connectionString))
   {
       // your code goes here
   }

Limitations of using a full connection string

Despite using a full ODBC connection string may be very convenient it comes with a limitation: it's length is limited to 1024 symbols (or sometimes more). It usually happens when API provider generates a very long Refresh Token when OAuth is at play. If you are using such a long ODBC connection string, you may get this error:

"Connection string exceeds maximum allowed length of 1024"

But there is a solution to this by storing the full connection string in a file. Follow the steps below to achieve this:

1. Open your ODBC data source.
2. Click Copy settings button to copy a full connection string (see the previous section on how to accomplish that).
3. Then create a new file, let's say, in C:\temp\odbc-connection-string.txt.
4. Continue by pasting the copied connection string into a newly created file and save it.
5. Finally, the last step! Just construct a shorter ODBC connection string using this format:

   DRIVER={ZappySys API Driver};SettingsFile=C:\temp\odbc-connection-string.txt

6. Our troubles are over! Now you should be able to use this connection string in C# with no problems.

Create Custom Stored Procedure in ZappySys Driver

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:
   

2. Enter the desired Procedure name and click on OK:
   

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>';
   

   
   

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';

   
   

5. Let's generate the SQL Server Query Code to make the API call using stored procedure. Go to Code Generator Tab, select language as SQL Server and click on Generate button the generate the code.
   As we already created the linked server for this Data Source, in that you just need to copy the Select Query and need to use the linked server name which we have apply on the place of [MY_API_SERVICE] placeholder.
   

   SELECT * FROM OPENQUERY([LS_TO_ONEDRIVE_IN_GATEWAY], 'EXEC usp_get_orders @fromdate=''1996-07-30''')

   
   

6. Now go to SQL served and execute that query and it will make the API call using stored procedure and provide you the response.
   

Create Custom Virtual Table in ZappySys Driver

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:
   

2. Enter the desired Table name and click on OK:
   

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'

   
   

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"

   
   

6. Let's generate the SQL Server Query Code to make the API call using stored procedure. Go to Code Generator Tab, select language as SQL Server and click on Generate button the generate the code.
   As we already created the linked server for this Data Source, in that you just need to copy the Select Query and need to use the linked server name which we have apply on the place of [MY_API_SERVICE] placeholder.
   

   SELECT * FROM OPENQUERY([LS_TO_ONEDRIVE_IN_GATEWAY], 'EXEC [usp_get_orders] ''1996-01-01''')

   
   

7. Now go to SQL served and execute that query and it will make the API call using stored procedure and provide you the response.
