Analyze Gumroad Data in Infragistics Reveal

Reveal is a data visualization solution provided by Infragistics and can be paired with the CData API Server to build dynamic dashboards from live Gumroad data. The CData API Server generates an OData API for Gumroad, which is natively consumable in Reveal. In this article, we walk through connecting to Gumroad in API Server and connecting to the API Server from Infragistics Reveal to create a simple dashboard.

Connect to Gumroad from API Server

CData API Server uses a straightforward, point-and-click interface to connect to data sources and generate APIs.

1. Open API Server and click Settings -> Connection -> Add Connection 👁 Adding a connection
   
2. Select "Gumroad" 👁 Selecting a Connector (Salesforce is shown).
   
3. Enter the necessary authentication properties to connect to Gumroad.

   Using OAuth Authentication

   To authenticate to Gumroad and connect to your own data or to allow other users to connect to their data, you can use the OAuth 2.0 standard. This is the recommended authentication method.

   First you need to register an OAuth application with Gumroad. You can create an OAuth application by visiting your Gumroad account settings at https://app.gumroad.com/settings/advanced and navigating to the Applications section.

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

   • AuthScheme: Set this to OAuth.
   • InitiateOAuth: Set this to GETANDREFRESH. The CData API Profile for Gumroad will automatically walk through the OAuth process in order to obtain the access token.
   • OAuthClientID: Set this to the client_id that is specified in your app settings.
   • OAuthClientSecret: Set this to the client_secret that is specified in your app settings.
   • CallbackURL: Set this to the Redirect URI you specified in your app settings.

   Example connection string

   Profile=C:\profiles\Gumroad.apip;AuthScheme=OAuth;InitiateOAuth=GETANDREFRESH;OAuthClientId=your_client_id;OAuthClientSecret=your_client_secret;CallbackUrl=your_callback_url;

Add Gumroad Resource Definitions in API Server

After connecting to Gumroad, create Resources, which represent API endpoints for Gumroad data.

1. Click Settings -> Resources -> Add Resource 👁 Adding a new resource
   
2. Select the Gumroad connection 👁 Selecting a connection (Salesforce is shown)
   
3. Select the table you wish to retrieve and click Next 👁 Selecting a Table (Salesforce is shown)
   
4. (Optional) Edit the resource to select specific fields and more
5. Save the settings

Add an API Server User

Create a User to connect to Gumroad from Reveal through API Server.

1. Click Settings -> Users
2. Click Add
3. Configure a User with access to the Gumroad Connection and Resource(s) 👁 Creating a new user
   

(Optional) Configure Cross-Origin Resource Sharing (CORS)

When accessing and connecting to multiple different domains from an application such as Ajax, there is a possibility of violating the limitations of cross-site scripting. In that case, configure the CORS settings in Settings -> Server.

• Enable cross-origin resource sharing (CORS): ON
• Allow all domains without '*': ON
• Access-Control-Allow-Methods: GET, PUT, POST, OPTIONS
• Access-Control-Allow-Headers: Authorization

Save the changes to the settings.
