C# Google Drive API Connector

In this article you will learn, how to integrate Google Drive data to C# without coding in few clicks (Live / Bi-directional connection to Google Drive). Read / write Google Drive data inside your app; perform many Google Drive operations without coding, just using easy to use high performance API Connector for Google Drive

Using Google Drive API Connector you will be able to connect, read and write data from within C#. Let's take a look at the steps below to see how exactly to accomplish that.

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

To get data from GoogleDrive using C# we first need to create a DSN - Data Source - which will access data from GoogleDrive, which later will be able to get using C#. Perform these steps:
  1. Install ZappySys ODBC PowerPack.

  2. Open ODBC Data Sources (x64):
    Open ODBC Data Source

  3. Create a User Data Source (User DSN) based on ZappySys API Driver:

    Create new API Connection for Google Drive

    You should create System DSN if client application is launched under Windows System Account, e.g. as a Windows Service.
    Launch ODBC Data Sources 32-bit version in case your client application is a 32-bit (x86) application (required only for System DSN).
  4. When a window appears, firstly give your data source a name if you haven't done that already, then select "Google Drive" from the list of Popular Connectors. If "Google Drive" is not present in the list, then click "Search Online" and download it. Then set the path to the one where you downloaded it. Finally, hit Continue >> button to continue configuring DSN:

    GoogleDriveDSN
    Google Drive
    ODBC DSN Template Selection

  5. Another window appears and it's time to configure the Connection Manager. Firstly, select Authentication Type, e.g. Token Authentication. Then select API Base URL (in most cases default one is the right one). More info is available in Authentication section.

    Steps to get Google Drive Credentials

    To make this work you will have to create an OAuth application. To register an App, perform the following steps (Detailed steps found in the help link at the end):

    1. Go to Google API Console
    2. From the Project Dropdown (usually found at the top bar) click Select Project
    3. On Project Propup click CREATE PROJECT
    4. Once project is created you can click Select Project to switch the context (You can click on Notification link or Choose from Top Dropdown)
    5. Click ENABLE APIS AND SERVICES
    6. Now we need to enable Google Drive API.
    7. Search Google Drive API. Select and click ENABLE
    8. Go to back to main screen of Google API Console
    9. Click OAuth Concent Screen Tab. Enter necessary details and Save.
    10. Click Credentials Tab
    11. Click CREATE CREDENTIALS (some where in topbar) and select OAuth Client ID option.
    12. When prompted Select Application Type as Desktop App and click Create to receive your ClientID and Secret. You can use this information now to configure Connection with UseCustomApp=true.

    API Reference (External Site)

    And finally, fill in all the required parameters and set optional parameters if needed.:

    GoogleDriveDSN
    Google Drive
    User Account [OAuth]
    https://www.googleapis.com/
    Required Parameters
    UseCustomApp Fill in the parameter...
    Optional Parameters
    ClientId Fill in the parameter...
    ClientSecret Fill in the parameter...
    Scope Fill in the parameter...
    RetryMode Fill in the parameter...
    RetryStatusCodeList Fill in the parameter...
    ODBC DSN Oauth Connection Configuration

  6. Once you configured a data source, you can preview data. Hit Preview tab, and use similar settings to preview data:
    ODBC ZappySys Data Source Preview

  7. Click OK to finish creating the data source

Read data in C# from the DSN

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

    "GoogleDriveDSN"
    Make ZappySys Driver call in c#

  2. Hit F5 to run the code and read the data:
    ZappySys Driver Output in c#

  3. Here is program's code in text format:

    
        using System;
        using System.Data.Odbc;
    
        namespace ConsoleApp
        {
        class Program
        {
        static void Main()
        {
        var dsn = "GoogleDriveDSN";
    
        using (var conn = new OdbcConnection(String.Format("DSN={0}", dsn)))
        {
        conn.Open();
        var cmd = new OdbcCommand("SELECT * FROM Products", conn);
        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();
        }
        }
        }
    
    

  4. If you want to avoid to be dependent on a DSN name 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 . Then in your C# code use Connection String when initializing OdbcConnection object, for example:

    
    using (var conn = new OdbcConnection("DRIVER={ZappySys API Driver};ServiceUrl=https://services.odata.org/V3/Northwind/Northwind.svc;Provider=OData;AuthName=Http;"))
    {
       // ...
    }
        
    

Create Custom Store 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 Store 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 Store Procedure

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

  3. Select the created Store Procedure and write the your desired store procedure and Save it and it will create the custom store 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 Store Procedure

  4. That's it now go to Preview Tab and Execute your Store 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'

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 dont 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.

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
