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

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

    ZappySys API Driver
    Create new System DSN for ZappySys API Driver
    You should create a System DSN (instead of a User DSN) if the client application is launched under a Windows System Account, e.g. as a Windows Service. If the client application is 32-bit (x86) running with a System DSN, use ODBC Data Sources (32-bit) instead of the 64-bit version.
  4. When the Configuration window appears give your data source a name if you haven't done that already, then select "Zoom" from the list of Popular Connectors. If "Zoom" 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:

    ZoomDSN
    Zoom
    ODBC DSN Template Selection

  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.

    OAuth App must be created under Admin Console > Channel > API > Settings. [API Help..]

    Steps to get Zoom Credentials : OAuth Authentication [OAuth]

    Perform the following steps to get the Zoom OAuth credentials (i.e. Client ID and Client Secret)

    1. Go to Zoom Marketplace Portal and sign in there.
    2. Once you successfully login then select "Build App" option from Develop dropdown from top left on the page.
    3. Click on Create button of OAuth panel section of page.
    4. Enter the name for your application and choose app type (Recommneded "Account-Level App") option for your API
    5. Then proceed with clicking Create button.
    6. In Redirect URL for OAuth enter this https://zappysys.com/oauth as Redirect URI and add it to allow lists.
    7. Copy Client ID and Client Secret here and paste it into Connection Manager Required Paramters section in respective place holders
    8. Add appropiate scopes from the Scopes menu option to the right side of page for your API as below :
      • meeting:read;
      • meeting:write;
      • user:read;
      • user:write;
      • user_info:read;
      • meeting:read:admin;
      • chat_channel:read;
      • chat_channel:write;

      • recording:read;
      • recording:write;
      • tsp:read
      • tsp:write;
      • user:read;
      • user:write;
      • user_info:read;
      • user_zak:read;
      • webinar:read;
      • webinar:write
    9. Click Generate Token button on Connection Manager UI to generate tokens.
    10. That's it!

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

    ZoomDSN

    ODBC DSN Oauth Connection Configuration

  6. 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:
    ODBC ZappySys Data Source Preview

  7. Click OK to finish creating the data source.

Read data in C# from the DSN

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

    "ZoomDSN";
    Make ZappySys Driver call in c#

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

  3. Here is the code in text format:

    
    using System;
    using System.Data.Odbc;
    
    namespace ConsoleApp {
        class Program {
            static void Main() {
                var dsn = "ZoomDSN";
                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();
            }
        }
    }
    

  4. 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 . 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://yourservices.provider.com/api/xxxx....;AuthName=Http;";
    
            using (var conn = new OdbcConnection(connectionString))
            {
            // ...
            }
        
    
    How to get ZappySys Driver Connection String?

    Please follow the instructions below to retrieve the connection string for the ZappySys driver.

    1. Click on the Windows Start menu.

    2. In the search bar, type ODBC and press Enter.

    3. From the search results, choose ODBC Data Sources or ODBC Data Sources (32-bit) or a similar option depending on your system architecture and ODBC driver configuration.

    4. Choose your data source from the list, then click on the Configure button.
    5. After opening the Data Source UI, you should copy the connection string to a Notepad or text file for reference.
    6. Click on Copy Connection String button.
      When you click 'Copy Connection String,' you may encounter the following option:
      Choose the third option All Settings to copy everything and click on OK button.
      zappysys-data-source-copy-connectionstring
      zappysys-data-source-copy-connectionstring

    That's it connection string has been successfully copied.

    How to Overcome the Long Connection String Issue

    This issue is typically caused when the connection string includes a long RefreshToken attribute (i.e. RefreshToken=xxxxxxxxxxxx...xxx, especially if it's more than 1,000 characters).

    A good solution is to supply the RefreshToken by a file. Simply copy and paste the RefreshToken into a text file and save it, and then pass that file path in the connection string instead of directly supplying the RefreshToken.

    Here is an example of a connection string that can cause the issue:

    
        var connectionString = "Driver={ZappySys API Driver};RefreshToken=xxxxxxxxxxxx...xxxxxxx;ServiceUrl=...;";
    
        using (var conn = new OdbcConnection(connectionString))
        {
        // ...
        }
    
    

    Here is an example of a connection string that has resolved the issue by moving the RefreshToken attribute to the file c:\my_refresh_token.txt:

    
        var connectionString = "Driver={ZappySys API Driver};RefreshTokenFile=c:\my_refresh_token.txt;ServiceUrl=...;";
    
        using (connectionString)
        {
        // ...
        }
    
    

Insider Insights

While using ExecuteNonQuery make sure to use output=0.

Sometime Executing `cmd.ExecuteNonQuery` in C# didn't trigger the API call immediately specifically for `INSERT`, `UPDATE`, or `DELETE` statement, as it only initiates the call when the iterator is requested. When using ExecuteNonQuery(), it's primarily intended for SQL statements that don't return data, such as UPDATE, INSERT, or DELETE. If you're not seeing any changes made by the UPDATE statement, there could be several reasons for this.

One potential reason, as you've mentioned, is related to deferred execution. In some cases, the changes made by the UPDATE statement might not be visible immediately, especially if you're not requesting any output from the query. In such cases, explicitly setting Output = 0 can force the iterator to be called, ensuring that the changes are applied.

Here's an example of how you might modify your code to include this:

using System;
using System.Data.Odbc;

namespace ConsoleApp {
    class Program {
        static void Main() {
            var dsn = "ZoomDSN";
            using (var conn = new OdbcConnection(String.Format("DSN={0}", dsn)))
            {
                conn.Open();
                
                //We're currently referring to the example with the Products table. Please substitute it with the table of your choice.
                var cmd =new OdbcCommand("UPDATE Products SET ProductName='Chai' Where ProductID=1 WITH(Output=0)", conn);
                
                //Increase the timeout duration from the default 30 seconds, which may be insufficient in certain scenarios
                cmd.CommandTimeout=600; // 600-Seconds
                
                // Execute the query
                int rowsAffected = cmd.ExecuteNonQuery();

                // Check the number of rows affected
                if (rowsAffected > 0)
                {
                    Console.WriteLine("Update successful.");
                }
                else
                {
                    Console.WriteLine("No rows were updated.");
                } 
            }
            Console.ReadKey();
        }
    }
}

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';

    ZappySys Driver - Execute Custom Store Procedure

  5. Let's generate the SQL Server Query Code to make the API call using store 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([MY_API_SERVICE], 'EXEC usp_get_orders @fromdate=''1996-07-30''')

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:
    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

  6. Let's generate the SQL Server Query Code to make the API call using store 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([MY_API_SERVICE], 'EXEC [usp_get_orders] ''1996-01-01''')

    ZappySys Driver - Generate SQL Server Query

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

 Generic Request
This is generic endpoint. Use this endpoint when some actions are not implemented by connector. Just enter partial URL (Required), Body, Method, Header etc. Most parameters are optional except URL.    [Read more...]
Parameter Description
Url API URL goes here. You can enter full URL or Partial URL relative to Base URL. If it is full URL then domain name must be part of ServiceURL or part of TrustedDomains
Body Request Body content goes here
IsMultiPart Check this option if you want to upload file(s) (i.e. POST RAW file data) or send data using Multi-Part encoding method (i.e. Content-Type: multipart/form-data). Multi-Part request allows you to mix key/value and upload files in same request. On the other hand raw upload allows only single file upload (without any key/value) ==== Raw Upload (Content-Type: application/octet-stream) ===== To upload single file in raw mode check this option and specify full file path starting with @ sign in the Body (e.g. @c:\data\myfile.zip ) ==== Form-Data / Multipart Upload (Content-Type: multipart/form-data) ===== To treat your Request data as multi part fields you must specify key/value pairs separated by new lines into RequestData field (i.e. Body). Each key value pair is entered on new-line and key/value are separated using equal sign (=). Preceding and trailing spaces are ignored also blank lines are ignored. If field value has some any special character(s) then use escape sequence (e.g. For NewLine: \r\n, For Tab: \t, For at (@): \@). When value of any field starts with at sign (@) its automatically treated as File you want to upload. By default file content type is determined based on extension however you can supply content type manually for any field using this way [ YourFileFieldName.Content-Type=some-content-type ]. By default File Upload Field always includes Content-Type in the request (non file fields do not have content-type by default unless you supply manually). For some reason if you dont want to use Content-Type header in your request then supply blank Content-Type to exclude this header altogather [e.g. SomeFieldName.Content-Type= ]. In below example we have supplied Content-Type for file2 and SomeField1, all other fields are using default content-type. See below Example of uploading multiple files along with additional fields. If some API requires you to pass Content-Type: multipart/form-data rather than multipart/form-data then manually set Request Header =&gt; Content-Type: multipart/mixed (it must starts with multipart/ else will be ignored). file1=@c:\data\Myfile1.txt file2=@c:\data\Myfile2.json file2.Content-Type=application/json SomeField1=aaaaaaa SomeField1.Content-Type=text/plain SomeField2=12345 SomeFieldWithNewLineAndTab=This is line1\r\nThis is line2\r\nThis is \ttab \ttab \ttab SomeFieldStartingWithAtSign=\@MyTwitterHandle
Filter Enter filter to extract array from response. Example: $.rows[*] --OR-- $.customers[*].orders[*]. Check your response document and find out hierarchy you like to extract
Headers Headers for Request. To enter multiple headers use double pipe or new line after each {header-name}:{value} pair
