Analyze Todoist Data in Infragistics Reveal

Reveal is a data visualization solution provided by Infragistics and can be paired with the CData Connect Server and Todoist Connector to build dynamic dashboards from live Todoist data. The CData Connect Server creates a virtual database for Todoist and can be used to generate an OData API (natively consumable in Reveal) for Todoist. In this article, we walk through connecting to Todoist in Connect Server and connecting to Connect Server from Infragistics Reveal to create a simple dashboard.

Add a Connect Server User

Create a User to connect to Todoist from Reveal through Connect Server.

1. Click Users -> Add
2. Configure a User
3. Click Save Changes and make note of the Authtoken for the new user

Connect to Todoist from Connect Server

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

1. Open Connect Server and click Connections
2. Select "Todoist" from Available Data Sources
3. Enter the necessary authentication properties to connect to Todoist.

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

   Todoist API Profile Settings

   To authenticate to Todoist, and connect to your own data or to allow other users to connect to their data, you can use the OAuth standard.

   First, you will need to register an OAuth application with Todoist. To do so, go to App Management Console, create a new application and configure a valid OAuth redirect URL. Your Oauth application will be assigned a client id and a client secret.

   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 client_id that is specified in you app settings.
   • OAuthClientSecret: Set this to the client_secret that is specified in you app settings.
   • CallbackURL: Set this to the Redirect URI that is specified in your app settings
4. Click Save Changes
5. Click Privileges -> Add and add the new user (or an existing user) with the appropriate permissions (SELECT is all that is required for Reveal).

Add Todoist OData Endpoints in Connect Server

After connecting to Todoist, create OData Endpoint for the desired table(s).

1. Click OData -> Tables -> Add Tables
2. Select the Todoist database
3. Select the table(s) you wish to work with and click Next
4. (Optional) Edit the resource to select specific fields and more
5. Save the settings

(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 OData -> Settings.

• 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 Connect Server configured, we can visualize Todoist data in Reveal.

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