Visualize Typeform Data in TIBCO Spotfire through OData
Integrate Typeform data into dashboards in TIBCO Spotfire.
OData is a major protocol enabling real-time communication among cloud-based, mobile, and other online applications. The CData API Server, when paired with the ADO.NET Provider for Typeform, provides Typeform data (or data from 200+ other ADO.NET Providers) to OData consumers like TIBCO Spotfire. This article shows how to use the API Server and Spotfire's built-in support for OData to access Typeform data in real time.
Set Up the API Server
Follow the steps below to begin producing secure Typeform OData services:
Deploy
The API Server runs on your own server. On Windows, you can deploy using the stand-alone server or IIS. On a Java servlet container, drop in the API Server WAR file. See the help documentation for more information and how-tos.
The API Server is also easy to deploy on Microsoft Azure, Amazon EC2, and Heroku.
Connect to Typeform
After you deploy the API Server and the ADO.NET Provider for Typeform, provide authentication values and other connection properties needed to connect to Typeform by clicking Settings -> Connections and adding a new connection in the API Server administration console.
Start by setting the Profile connection property to the location of the TypeForm Profile on disk (e.g. C:\profiles\TypeForm.apip). Next, set the ProfileSettings connection property to the connection string for TypeForm (see below).
TypeForm API Profile Settings
Authentication to TypeForm uses the OAuth standard.
To authenticate to TypeForm, you must first register and configure an OAuth application with TypeForm here: https://admin.typeform.com/account#/section/tokens. Your app will be assigned a client ID and a client secret which can be set in the connection string. More information on setting up an OAuth application can be found at https://developer.typeform.com/get-started/.
Note that there are several different use scenarios which all require different redirect URIs:
- CData Desktop Applications: CData desktop applications (Sync, API Server, ArcESB) accept OAuth tokens at /src/oauthCallback.rst. The host and port is the same as the default port used by the application. For example, if you use http://localhost:8019/ to access CData Sync then the redirect URI will be http://localhost:8019/src/oauthCallback.rst.
- CData Cloud Applications: CData cloud applications are similar to their desktop counterparts. If you access Connect Cloud at https://1.2.3.4/ then you should use the redirect https://1.2.3.4/src/oauthCallback.rst.
- Desktop Application: When using a desktop application, the URI https://localhost:33333 is recommended.
- Web Application: When developing a web application using the driver, use your own URI here such as https://my-website.com/oauth.
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 your app settings.
- OAuthClientSecret: Set this to Client Secret that is specified in your app settings.
- CallbackURL: Set this to the Redirect URI you specified in your app settings.
When you configure the connection, you may also want to set the Max Rows connection property. This will limit the number of rows returned, which is especially helpful for improving performance when designing reports and visualizations.
You can then choose the Typeform entities you want to allow the API Server access to by clicking Settings -> Resources.
Authorize API Server Users
After determining the OData services you want to produce, authorize users by clicking Settings -> Users. The API Server uses authtoken-based authentication and supports the major authentication schemes. Access can also be restricted based on IP address; by default only connections to the local machine are allowed. You can authenticate as well as encrypt connections with SSL.
Create Data Visualizations on External Typeform Data
- Open Spotfire and click Add Data Tables -> OData.
- In the OData Connection dialog, enter the following information:
- Service URL: Enter the API Server's OData endpoint. For example:
http://localhost:8032/api.rsc - Authentication Method: Select Username and Password.
- Username: Enter the username of an API Server user. You can create API users on the Security tab of the administration console.
- Password: Enter the authtoken of an API Server user.
- Service URL: Enter the API Server's OData endpoint. For example:
- Select the tables and columns you want to add to the dashboard. This example uses Tags.
- If you want to work with the live data, click the Keep Data Table External option. This option enables your dashboards to reflect changes to the data in real time.
If you want to load the data into memory and process the data locally, click the Import Data Table option. This option is better for offline use or if a slow network connection is making your dashboard less interactive.
- After adding tables, the Recommended Visualizations wizard is displayed. When you select a table, Spotfire uses the column data types to detect number, time, and category columns. This example uses Title in the Numbers section and Id in the Categories section.
After adding several visualizations in the Recommended Visualizations wizard, you can make other modifications to the dashboard. For example, you can apply a filter: After clicking the Filter button, the available filters for each query are displayed in the Filters pane.
