Create ODBC data source

ZappySys provides specialized ODBC drivers to connect to various API formats. Depending on your API's response type, follow the relevant configuration section below:

• JSON Driver
  Best for REST APIs responding with JSON data.
• XML Driver
  Designed for SOAP services or APIs returning XML strings.
• CSV Driver
  Use this for APIs returning CSV data or for parsing flat files.

Using JSON Driver

1. Download and install ODBC PowerPack (if you haven't already).

2. Search for odbc and open the ODBC Data Sources (64-bit):

   

3. Create a User data source (User DSN) based on the ZappySys JSON Driver driver:

   ZappySys JSON Driver

   
   • Create and use a User DSN if the client application runs under a User Account. This is the ideal option at design time (e.g., when developing in Visual Studio). Use it for both types of applications (64-bit and 32-bit).
   • Create and use a System DSN if the client application runs under a System Account (e.g., as a Windows Service). This is usually the required option in a production environment. If your Windows Service is a 32-bit application, you must use the 32-bit ODBC Data Source Administrator to configure this

4. Select Url or File and paste the following Url for this example OR you can load existing connection string as per this article.
   

   NOTE: Here for demo, We are using odata API, but you need to refer your own API documentation and based on that you need to use your own API URL and need to configure connection based on API Authentication type

   https://services.odata.org/V3/Northwind/Northwind.svc/Customers?$format=json

5. Now enter JSONPath expression in Array Filter textbox to extract only specific part of JSON file as below ($.value[*] will get content of value attribute from JSON document. Value attribute is array of JSON documents so we have to use [*] to indicate we want all records of that array)
   

   NOTE: Here, We are using our desired filter, but you need to select your desired filter based on your requirement.

   
   Click on Test Connection button to view whether the Test Connection is SUCCESSFUL or Not.
   $.value[*]
   

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

7. Click OK to finish creating the data source

8. That's it; we are done. In a few clicks we configured the call to JSON API using ZappySys JSON Connector.

Using XML Driver

1. Download and install ODBC PowerPack (if you haven't already).

2. Search for odbc and open the ODBC Data Sources (64-bit):

   

3. Create a User data source (User DSN) based on the ZappySys XML Driver driver:

   ZappySys XML Driver

   
   • Create and use a User DSN if the client application runs under a User Account. This is the ideal option at design time (e.g., when developing in Visual Studio). Use it for both types of applications (64-bit and 32-bit).
   • Create and use a System DSN if the client application runs under a System Account (e.g., as a Windows Service). This is usually the required option in a production environment. If your Windows Service is a 32-bit application, you must use the 32-bit ODBC Data Source Administrator to configure this

4. Select Url or File and paste the following Url for this example OR you can load existing connection string as per this article.
   

   NOTE: Here for demo, We are using odata API, but you need to refer your own API documentation and based on that you need to use your own API URL and need to configure connection based on API Authentication type

   https://services.odata.org/V3/Northwind/Northwind.svc/Customers

5. Now enter Path expression in Array Filter textbox to extract only specific part of XML file as below ($.feed.entry[*] will get content of entry attribute from XML document. Entry attribute is array of XML documents so we have to use [*] to indicate we want all records of that array)
   

   NOTE: Here, We are using our desired filter, but you need to select your desired filter based on your requirement.

   
   Click on Test Connection button to view whether the Test Connection is SUCCESSFUL or Not.
   $.feed.entry[*]
   

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

7. Click OK to finish creating the data source.

8. That's it; we are done. In a few clicks we configured the call to XML API using ZappySys XML Connector.

Using CSV Driver

1. Download and install ODBC PowerPack (if you haven't already).

2. Search for odbc and open the ODBC Data Sources (64-bit):

   

3. Create a User data source (User DSN) based on the ZappySys CSV Driver driver:

   ZappySys CSV Driver

   
   • Create and use a User DSN if the client application runs under a User Account. This is the ideal option at design time (e.g., when developing in Visual Studio). Use it for both types of applications (64-bit and 32-bit).
   • Create and use a System DSN if the client application runs under a System Account (e.g., as a Windows Service). This is usually the required option in a production environment. If your Windows Service is a 32-bit application, you must use the 32-bit ODBC Data Source Administrator to configure this

4. Select Url or File.
   

   Read CSV API in Alteryx

   • Paste the following Url. In this example, We are using Zip format CSV File URL, but you need to refer your CSV File/URL.

     https://zappysys.com/downloads/files/test/cust-1.csv.zip
     Click on Test Connection button to view whether the Test Connection is SUCCESSFUL or Not.

   Read CSV File in Alteryx

   • You can use pass single file or multiple file path using wildcard pattern in path and you can use select single file by clicking [...] path button or multiple file using wildcard pattern in path.
     

     Note: If you want to operation with multiple files then use wild card pattern as below
     (when you use wild card pattern in source path then system will treat target path as folder regardless you end with slash)
     
     C:\SSIS\Test\reponse.csv (will read only single reponse.csv file)
     C:\SSIS\Test\j*.csv (all files starting with file name j)
     C:\SSIS\Test\*.csv (all files with .csv Extension and located under folder subfolder)
     

     Click on Test Connection button to view whether the Test Connection is SUCCESSFUL or Not.

5. Once you configured a data source, you can preview data. Hit Preview tab, and use similar settings to preview data:
   

6. Click OK to finish creating the data source

7. That's it; we are done. In a few clicks we configured the read the CSV data using ZappySys CSV Connector.

Read REST API data in Alteryx Designer (workstation)

Here we will be reading REST API data on your workstation using Alteryx Designer. Follow the steps below to connect via ODBC and run your workflow locally.

1. Open Alteryx Designer.

2. First, verify your DCM Settings to ensure you can access ODBC drivers. Go to Options > User Settings > Edit User Settings.

   If DCM Mode is set to DCM Only, change it to DCM Optional if you would like to access the legacy Generic ODBC Connection.

   
   After changing this setting, you may need to click Save and restart the connection window for the "Generic ODBC" icon to appear.

3. Drag an Input Data tool onto your Alteryx canvas.

   

4. In the Configuration pane, click Set Up a Connection.

   

5. Note for DCM Users: If your environment has DCM (Data Connection Manager) enabled, the classic "Generic ODBC" icon may be hidden. To find it, select Data sources on the left and type "ODBC" in the search bar.

6. Once the ODBC window opens, click Connect Asset and select your RestApiDSN DSN from the list.

   
   Ensure you have configured a 64-bit System DSN in the Windows ODBC Data Source Administrator before this step.

7. After selecting your DSN, configure your SQL Query in the Input Data tool configuration:

   

8. To save your data, drag an Output Data tool and connect it to the Input Data tool.

9. Configure the Output Data tool to write to a CSV file:

   

10. Press Run (Ctrl+R) to execute the workflow. Verify the results in the Results Window at the bottom.

    

Using DSN-less Connection String

If you prefer to use a DSN-less connection string instead of creating an ODBC data source in Alteryx, you can enter the connection string directly in the Input Data tool's connection setup:

Deploy workflow and run on server (e.g. Alteryx Server)

To run your Alteryx workflow on a server (e.g. Alteryx Server or a machine used for scheduled runs), install ZappySys ODBC PowerPack and configure the same DSN on that server so the workflow can connect to REST API data.

1. On the server where the workflow will run, download and install ODBC PowerPack (v2.2.1 or higher for Alteryx support).
2. Open ODBC Data Sources (64-bit) on the server and create a System DSN with the same name and settings as on your workstation (use the same driver and connection configuration). An easy way to copy your workstation DSN settings to the server is described in How to copy ODBC DSN or Data Gateway settings to another server (use Copy Settings on the workstation, then Load settings on the server).
3. Deploy or publish your workflow to the server (e.g. upload to Alteryx Server or copy the workflow to the server).
4. Run the workflow on the server; it will use the DSN you created in step 2 to connect to REST API.

Optional: Centralized data access via ZappySys Data Gateway

In some situations, you may need to provide REST API data access to multiple users or services. Configuring the data source on a Data Gateway creates a single, centralized connection point for this purpose.

This configuration provides two primary advantages:

• Centralized data access
  The data source is configured once on the gateway, eliminating the need to set it up individually on each user's machine or application. This significantly simplifies the management process.
• Centralized access control
  Since all connections route through the gateway, access can be governed or revoked from a single location for all users.

To achieve this, you must first create a data source in the Data Gateway (server-side) and then create an ODBC data source in Alteryx (client-side) to connect to it.

Let's not wait and get going!

Create REST API data source in the gateway

In this section we will create a data source for REST API in the Data Gateway. Let's follow these steps to accomplish that:

1. Search for gateway in the Windows Start Menu and open ZappySys Data Gateway Configuration:

   

2. Go to the Users tab and follow these steps to add a Data Gateway user:

   • Click the Add button
   • In the Login field enter a username, e.g., john
   • Then enter a Password
   • Check the Is Administrator checkbox
   • Click OK to save
   

3. Now we are ready to add a data source:

   • Click the Add button
   • Give the Data source a name (have it handy for later)
   • Then select Native - ZappySys JSON, XML or CSV Driver
   • Finally, click OK
   RestApiDSN

   ZappySys JSON, XML or CSV Driver

   

4. When the ZappySys JSON, XML or CSV Driver configuration window opens, go back to ODBC Data Source Administrator where you already have the REST API ODBC data source created and configured, and follow these steps on how to Import data source configuration into the Gateway:

   • Open ODBC data source configuration and click Copy settings:
     

     ZappySys JSON, XML or CSV Driver - Configuration [Version: 2.0.1.10418]

     ZappySys JSON, XML or CSV Driver - REST API

     Read and write REST API data effortlessly. Streamline, manage, and automate JSON, XML, and CSV from web URLs for analytics, reporting, and data pipelines — almost no coding required.

     RestApiDSN

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

   • Then go to Data Gateway configuration and in data source configuration window click Load settings:

     RestApiDSN

     

     ZappySys JSON, XML or CSV Driver - Configuration [Version: 2.0.1.10418]

     Read and write REST API data effortlessly. Streamline, manage, and automate JSON, XML, and CSV from web URLs for analytics, reporting, and data pipelines — almost no coding required.

     RestApiDSN

     
   • Once a window opens, just paste the settings by pressing CTRL+V or by clicking right mouse button and then Paste option.

5. Once done, go to the Network Settings tab and Add a firewall rule for inbound traffic:

   
   • This will initially allow all inbound traffic.
   • Click Edit IP filters to restrict access to specific IP addresses or ranges.

6. Crucial Step: After creating or modifying the data source, you must:

   • Click the Save button to persist your changes.
   • Hit Yes when prompted to restart the Data Gateway service.

   This ensures all changes are properly applied:

   
   Skipping this step may cause the new settings to fail, preventing you from connecting to the data source.

Create ODBC data source to connect to the gateway

In this part we will create an ODBC data source to connect to the ZappySys Data Gateway from Alteryx. To achieve that, let's perform these steps:

1. Search for odbc and open the ODBC Data Sources (64-bit):

   

2. Create a User data source (User DSN) based on the ODBC Driver 17 for SQL Server driver:

   ODBC Driver 17 for SQL Server

   
   If you don't see the ODBC Driver 17 for SQL Server driver in the list, choose a similar version.

3. Then set a Name for the data source (e.g. Gateway) and the address of the Data Gateway:

   ZappySysGatewayDSN

   localhost,5000

   
   Make sure you separate the hostname and port with a comma, e.g. localhost,5000.

4. Proceed with the authentication part:

   • Select SQL Server authentication
   • In the Login ID field enter the user name you created in the Data Gateway, e.g., john
   • Set Password to the one you configured in the Data Gateway
   

5. Then set the default database property to RestApiDSN (the one we used in the Data Gateway):

   RestApiDSN

   RestApiDSN

   
   Make sure to type the data source name manually or copy/paste it directly into the field. Using the dropdown might fail because the Trust server certificate option is not enabled yet (next step).

6. Continue by checking the Trust server certificate option:

   

7. Once you do that, test the connection:

   

8. If the connection is successful, everything is good:

   

9. Done!

We are ready to move to the final step. Let's do it!

Access data in Alteryx via the gateway

Finally, we are ready to read data from REST API in Alteryx via the Data Gateway. Follow these final steps:

1. Go back to Alteryx.

2. Drag an Input Data tool onto your Alteryx canvas.

   

3. In the Configuration pane, click Set Up a Connection.

   

4. Note for DCM Users: If your environment has DCM (Data Connection Manager) enabled, the classic "Generic ODBC" icon may be hidden. To find it, select Data sources on the left and type "ODBC" in the search bar.

5. Once the ODBC window opens, click Connect Asset and select your ZappySysGatewayDSN DSN from the list.

   
   Ensure you have configured a 64-bit System DSN in the Windows ODBC Data Source Administrator before this step.

6. Read the data the same way we discussed at the beginning of this article.

7. That's it!

Now you can connect to REST API data in Alteryx via the Data Gateway.

Configuring pagination in the REST API Driver

ZappySys REST API Driver equips users with powerful tools for seamless data extraction and management from REST APIs, leveraging advanced pagination methods for enhanced efficiency. These options are designed to handle various types of pagination structures commonly used in APIs. Below are the detailed descriptions of these options:

1. Page-based Pagination: This method works by retrieving data in fixed-size pages from the Rest API. It allows you to specify the page size and navigate through the results by requesting different page numbers, ensuring that you can access all the data in a structured manner.

2. Offset-based Pagination: With this approach, you can extract data by specifying the starting point or offset from which to begin retrieving data. It allows you to define the number of records to skip and fetch subsequent data accordingly, providing precise control over the data extraction process.

3. Cursor-based Pagination: This technique involves using a cursor or a marker that points to a specific position in the dataset. It enables you to retrieve data starting from the position indicated by the cursor and proceed to subsequent segments, ensuring that you capture all the relevant information without missing any records.

4. Token-based Pagination: In this method, a token serves as a unique identifier for a specific data segment. It allows you to access the next set of data by using the token provided in the response from the previous request. This ensures that you can systematically retrieve all the data segments without duplication or omission.

Utilizing these comprehensive pagination features in the ZappySys REST API Driver facilitates efficient data management and extraction from REST APIs, optimizing the integration and analysis of extensive datasets.
