Analyze Foursquare 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 Foursquare data. The CData API Server generates an OData API for Foursquare, which is natively consumable in Reveal. In this article, we walk through connecting to Foursquare in API Server and connecting to the API Server from Infragistics Reveal to create a simple dashboard.

Connect to Foursquare 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
2. Select "Foursquare"
3. Enter the necessary authentication properties to connect to Foursquare.

   Using API Key Authentication

   Foursquare Places API uses Service Key (Bearer token) authentication. To obtain a Service Key:

   1. Go to the Foursquare Developer Console at https://foursquare.com/developers/
   2. Create a new project or select an existing one
   3. Navigate to the API Keys section
   4. Generate a new Service Key for the Places API

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

   • AuthScheme: Set this to APIKey.
   • ServiceKey: Set this to your Foursquare Service Key obtained from the Developer Console.
   • XPlacesApiVersion: (Optional) Set this to the API version date. Defaults to 2025-06-17.

   Example APIKey connection string

   Profile=C:\profiles\Foursquare.apip;AuthScheme=APIKey;ProfileSettings='APIKey=your_personal_access_token';
   

   

Add Foursquare Resource Definitions in API Server

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

1. Click Settings -> Resources -> Add Resource
2. Select the Foursquare connection
3. Select the table you wish to retrieve and click Next
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 Foursquare from Reveal through API Server.

1. Click Settings -> Users
2. Click Add
3. Configure a User with access to the Foursquare Connection and Resource(s)

(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.

Create a Dashboard in Reveal

With the API Server configured, we can visualize Foursquare data in Reveal.

1. Log into Reveal and click Dashboards -> New
2. Click Data Source -> OData Feed
3. Specify the API Server API endpoint URL, for example: https://serverurl/api.rsc
4. Select Generic Credentials and specify the API Server username and authentication token
5. Select the entity you wish to visualize
6. Select fields and choose a chart type
