Import Real-Time Coinbase Data in ColdFusion to Build Applications


Use CData JDBC drivers to import and use Coinbase data in ColdFusion.

Adobe ColdFusion is a web and mobile application development platform. It uses its own scripting language, ColdFusion Markup Language (CFML), to create data-driven websites as well as generate remote services, such as REST.

When ColdFusion is paired with the CData API Driver for JDBC, you can link your ColdFusion web and mobile applications to operational Coinbase data. This allows for your applications to be more robust and complete. This article details how to use the JDBC driver to create a table populated with Coinbase data from within a ColdFusion markup file.

With built-in optimized data processing, the CData JDBC Driver offers unmatched performance for interacting with live Coinbase data. When you issue complex SQL queries to Coinbase, the driver pushes supported SQL operations, like filters and aggregations, directly to Coinbase and utilizes the embedded SQL engine to process unsupported operations client-side (often SQL functions and JOIN operations). Its built-in dynamic metadata querying allows you to work with and analyze Coinbase data using native data types.

Configuring the Connection to Coinbase

You will need a JDBC connection string to establish a connection between Coldfusion and Coinbase.

Start by setting the Profile connection property to the location of the Coinbase Profile on disk (e.g. C:\profiles\Coinbase.apip). Next, set the ProfileSettings connection property to the connection string for Coinbase (see below).

Coinbase API Profile Settings

Coinbase uses OAuth-based authentication.

First you need to register an OAuth app with Coinbase. This is done from your account under 'Settings' > 'API Access' > 'New OAuth2 Application'.

After setting the following connection properties, you are ready to connect:

  • AuthScheme: Set this to OAuth.
  • InitiateOAuth: Set this to GETANDREFRESH. You can use InitiateOAuth to manage the process to obtain the OAuthAccessToken.
  • OAuthClientId: Set this to the ClientID that is specified in you app settings.
  • OAuthClientSecret: Set this to the ClientSecret that is specified in you app settings.
  • CallbackURL: Set this to the Redirect URI you specified in your app settings.

Built-in Connection String Designer

For assistance in constructing the JDBC URL, use the connection string designer built into the Coinbase JDBC Driver. Either double-click the JAR file or execute the jar file from the command-line.

java -jar cdata.jdbc.api.jar

Adding a Data Source and Creating a Table

After configuring the connection, follow the steps below to add the CData JDBC Driver to ColdFusion's lib directory, add a new data source, test the connection, create a ColdFusion markup file, and, finally, make a real-time connection with Coinbase data and display it in a table written in the ColdFusion Markup Language, or CFML:

  1. Copy the JDBC Driver for Coinbase and lic file from "C:\Program Files\CData[product_name]\lib" to "C:\ColdFusion2021\cfusion\wwwroot\WEB-INF\lib". cdata.jdbc.api.jar cdata.jdbc.api.lic

    Note: If you do not copy the .lic file with the jar, you will see a licensing error that indicates you do not have a valid license installed. This is true for both the trial and full versions.

  2. From the ColdFusion administrator interface, choose Data & Services.
  3. Here, we can "Add New Data Source". The data source name can be any name, provided it conforms to the ColdFusion variable naming conventions. For our JDBC driver, choose "other", then click the "Add" button.
  4. Next, populate the driver properties.
    • JDBC URL will need to be in the format: jdbc:api:|connectionString|.
    • A typical connection string looks like this:

      jdbc:api:Profile=C:\profiles\Coinbase.apip;Authscheme=OAuth;OAuthClientId=your_client_id;OAuthClientSecret=your_client_secret;CallbackUrl=your_callback_url;

    • The Driver Class is: cdata.jdbc.api.APIDriver
    • The Driver Name is arbitrary and simply used to recognize the data source in the ColdFusion administration console.
  5. Now, test the connection by clicking the check mark to the left of the CDataCoinbaseJDBC data source you just created. When the data source reports an "OK" status, it is ready for use.
  6. Next, create a new ColdFusion Markup file (.cfm) and place it in the wwwroot directory ("C:\ColdFusion2021\cfusion\wwwroot") for ColdFusion.

    The following code queries the data source: 

                
        <cfquery name="CoinbaseQuery" dataSource="CDataCoinbaseJDBC"> 
          SELECT * FROM Deposits 
        </cfquery>
    And a CFTable can be used to quickly output the table in HTML: 
                
          <cftable  
          query = "CoinbaseQuery" 
          border = "1" 
          colHeaders 
          colSpacing = "2" 
          headerLines = "2" 
          HTMLTable 
          maxRows = "500" 
          startRow = "1"> 

          <cfcol header="<b>Id</b>" align="Left" width=2 text="Id"/> 

          <cfcol header="<b>Amount</b>" align="Left" width=15 text="Amount"/> 

          ...

        </cftable>
    Full code, including the HTML portion is available below: 
                
        <html> 
        <head><title>CData Software | Coinbase Deposits Table Demo </title></head> 
        <body> 
        <cfoutput>#ucase("Coinbase Deposits Table Demo")#</cfoutput> 
        <cfquery name="CoinbaseQuery" dataSource="CDataCoinbaseJDBC"> 

          SELECT * FROM Deposits 

        </cfquery> 
        <cftable  
          query = "CoinbaseQuery" 
          border = "1" 
          colHeaders 
          colSpacing = "2" 
          headerLines = "2" 
          HTMLTable 
          maxRows = "500" 
          startRow = "1"> 
          <cfcol header="<b>Id</b>" align="Left" width=2 text="Id"/> 

          <cfcol header="<b>Amount</b>" align="Left" width=15 text="Amount"/> 

          ...

        </cftable> 
        </body> 

        </html>
  7. Finally, run the code locally in a browser at the default port of 8500. It produces a table populated with Coinbase data!

As a note, the CData JDBC Drivers also support parameterized queries using the cfqueryparam element. For example: SELECT * FROM Account WHERE name =
