Search Typeform External Objects in Salesforce Connect (API Server)

The CData API Server enables you to access Typeform data from cloud-based applications like the Salesforce console and mobile applications like the Salesforce1 Mobile App. In this article, you will use the API Server and Salesforce Connect to access Typeform external objects alongside standard Salesforce objects.

Set Up the API Server

If you have not already done so, download the CData API Server. Once you have installed the API Server, follow the steps below to begin producing secure Typeform OData services:

Connect to Typeform

To work with Typeform data from Salesforce Connect, we start by creating and configuring a Typeform connection. Follow the steps below to configure the API Server to connect to Typeform data:

1. First, navigate to the Connections page.
2. Click Add Connection and then search for and select the Typeform connection.
3. Enter the necessary authentication properties to connect to Typeform.

   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.
   
4. After configuring the connection, click Save & Test to confirm a successful connection.

Configure API Server Users

Next, create a user to access your Typeform data through the API Server. You can add and configure users on the Users page. Follow the steps below to configure and create a user:

1. On the Users page, click Add User to open the Add User dialog.
2. Next, set the Role, Username, and Privileges properties and then click Add User.
3. An Authtoken is then generated for the user. You can find the Authtoken and other information for each user on the Users page:

Creating API Endpoints for Typeform

Having created a user, you are ready to create API endpoints for the Typeform tables:

1. First, navigate to the API page and then click Add Table .
2. Select the connection you wish to access and click Next.
3. With the connection selected, create endpoints by selecting each table and then clicking Confirm.

Gather the OData Url

Having configured a connection to Typeform data, created a user, and added resources to the API Server, you now have an easily accessible REST API based on the OData protocol for those resources. From the API page in API Server, you can view and copy the API Endpoints for the API:

Connect to Typeform Data as an External Data Source

Follow the steps below to connect to the feed produced by the API Server.

1. Log into Salesforce and click Setup -> Develop -> External Data Sources.
2. Click New External Data Source.
3. Enter values for the following properties:
   • External Data Source: Enter a label to be used in list views and reports.
   • Name: Enter a unique identifier.
   • Type: Select the option "Salesforce Connect: OData 4.0".

   • URL: Enter the URL to the OData endpoint of the API Server. The format of the OData URL is https://your-server:your-port/api.rsc.

     Note that plain-text is suitable for only testing; for production, use TLS.

4. Select JSON in the Format menu.

5. In the Authentication section, set the following properties:
   • Identity Type: If all members of your organization will use the same credentials to access the API Server, select "Named Principal". If the members of your organization will connect with their own credentials, select "Per User".
   • Authentication Protocol: Select Password Authentication to use basic authentication.
   • Certificate: Enter or browse to the certificate to be used to encrypt and authenticate communications from Salesforce to your server.
   • Username: Enter the username for a user known to the API Server.
   • Password: Enter the user's authtoken.

Synchronize Typeform Objects

After you have created the external data source, follow the steps below to create Typeform external objects that reflect any changes in the data source. You will synchronize the definitions for the Typeform external objects with the definitions for Typeform tables.

1. Click the link for the external data source you created.
2. Click Validate and Sync.
3. Select the Typeform tables you want to work with as external objects.

Access Typeform Data as Salesforce Objects

After adding Typeform data as an external data source and syncing Typeform tables with Typeform external objects, you can use the external objects just as you would standard Salesforce objects.

• Create a new tab with a filter list view:

  

• Display related lists of Typeform external objects alongside standard Salesforce objects:

  

Troubleshooting

You can use the following checklist to avoid typical connection problems:

• Ensure that your server has a publicly accessible IP address. Related to this check, but one layer up, at the operating system layer, you will also need to ensure that your firewall has an opening for the port the API Server is running on. At the application layer, ensure that you have added trusted IP addresses on the Settings -> Security tab of the administration console.
• Ensure that you are using a connection secured by an SSL certificate from a commercial, trusted CA. Salesforce does not currently accept self-signed certificates or internal CAs.

• Ensure that the server you are hosting the API Server on is using TLS 1.1 or above. If you are using the .NET API Server, you can accomplish this by using the .NET API Server's embedded server.

  If you are using IIS, TLS 1.1 and 1.2 are supported but not enabled by default. To enable these protocols, refer to the how-to on MSDN and the Microsoft technical reference.

  If you are using the Java edition, note that TLS 1.2 is enabled by default in Java 8 but not in Java 6 or 7. If you are using these earlier versions, you can refer to this this Oracle how-to.
