FastSpring Connector for C# Read / write FastSpring data related to Orders, Subscriptions, Quotes, Products, Accounts and more without coding. In this article you will learn how to quickly and efficiently integrate FastSpring data in C#. We will use high-performance FastSpring Connector to easily connect to FastSpring and then access the data inside C#. Let's follow the steps below to see how we can accomplish that! Download Documentation FastSpring 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 FastSpring using C# we first need to create a DSN (Data Source) which will access data from FastSpring. 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 "FastSpring" from the list of Popular Connectors. If "FastSpring" 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:

   FastspringDSN

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.

    API Credentials [Http]

   Steps how to get and use FastSpring credentials : API Credentials [Http]
   

   Here is how to obtain FastSpring API credentials:

   1. In the FastSpring portal, navigate to Developer Tools > APIs > API Credentials.
   2. Click Create, FastSpring will automatically generate your Username and Password. Copy them, we will need them in the next step:
      WARNING: Securely store the credentials for future reference.
   3. Now go to SSIS package or ODBC data source and use this token in API Credentials authentication configuration:
      • In the UserName field paste the Username value you copied in the previous step.
      • In the Password field paste the Password value you copied in the previous step.
   4. Click Test Connection to confirm the connection is working.
   5. Done! Now you are ready to use FastSpring Connector!

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

   FastspringDSN

   FastSpring

   API Credentials [Http]

   https://api.fastspring.com

   Required Parameters
   UserName	Fill-in the parameter...
   Password	Fill-in the parameter...
   Optional Parameters
   RetryMode	RetryWhenStatusCodeMatch
   RetryStatusCodeList	429
   RetryCountMax	5
   RetryMultiplyWaitTime	True
   Your Webstore URL	https://YOUR-STORE.onfastspring.com

   

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:

   Read / write FastSpring data related to Orders, Subscriptions, Quotes, Products, Accounts and more without coding.

   FastspringDSN

   

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 FastSpring. Hit OK button to use this query in the next step.

   SELECT * FROM Orders

   
   Some parameters configured in this window will be passed to the FastSpring 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 - FastSpring

   Read / write FastSpring data related to Orders, Subscriptions, Quotes, Products, Accounts and more without coding.

   FastspringDSN

   SELECT * FROM Orders

   
   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 FastSpring 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 FastSpring 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:
   

   "FastspringDSN";

   

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 = "FastspringDSN";
               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 - Configuration [Version: 2.0.1.10418]

   ZappySys API Driver - FastSpring

   Read / write FastSpring data related to Orders, Subscriptions, Quotes, Products, Accounts and more without coding.

   FastspringDSN

   
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://api.fastspring.com;CredentialType=Basic;";
   
   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.
