Edit and Search Excel Online External Objects in Salesforce Connect (API Server)

The CData API Server enables you to access Excel Online 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 Excel Online 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 Excel Online OData services:

Connect to Excel Online

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

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

   You can connect to a workbook by providing authentication to Excel Online and then setting the following properties:

   • Workbook: Set this to the name or Id of the workbook.

     If you want to view a list of information about the available workbooks, execute a query to the Workbooks view after you authenticate.

   • UseSandbox: Set this to true if you are connecting to a workbook in a sandbox account. Otherwise, leave this blank to connect to a production account.

   You use the OAuth authentication standard to authenticate to Excel Online. See the Getting Started section in the help documentation for a guide. Getting Started also guides you through executing SQL to worksheets and ranges.

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

Configure API Server Users

Next, create a user to access your Excel Online 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 Excel Online

Having created a user, you are ready to create API endpoints for the Excel Online 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 Excel Online 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 Excel Online 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 the Writable External Objects option.

5. Select JSON in the Format menu.

6. 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 Excel Online Objects

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

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

Access Excel Online Data as Salesforce Objects

After adding Excel Online data as an external data source and syncing Excel Online tables with Excel Online 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 Excel Online external objects alongside standard Salesforce objects:

  
• Create, read, update, and delete Excel Online objects from tabs on the Salesforce dashboard:

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.
