Edit and Search Sage 50 UK External Objects

The CData API Server, when paired with the (or any of 200+ other ADO.NET Providers), enables you to access Sage 50 UK 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 Sage 50 UK external objects alongside standard Salesforce objects.

Set Up the API Server

Follow the steps below to begin producing secure Sage 50 UK 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. You can find guides to deploying the API Server on Azure, Amazon EC2, and Heroku in the CData KB.

Connect to Sage 50 UK

After you deploy the API Server and the , provide authentication values and other connection properties needed to connect to Sage 50 UK by clicking Settings -> Connection and adding a new connection in the API Server administration console.

Note: Only Sage 50 UK 2012 and above are supported.

The User and Password properties, under the Connection section, must be set to valid Sage 50 UK user credentials. These values will be the same used to log in to the Sage 50 UK software.

Additionally, the URL property, under the Connection section, will need to be set to the address of the company dataset desired. To obtain the address, do the following:

1. If you have not already done so, open the Sage 50 UK software.
2. Click Tools -> Internet Options.
3. Select the SData Settings tab.
4. Click the Details button next to Sage 50 Accounts. A window is displayed containing a list of company names along with the address to their corresponding datasets.
5. Set the URL property to the value in the address field next to the company desired.

You can then choose the Sage 50 UK 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.

Connect to Sage 50 UK 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 Sage 50 UK Objects

After you have created the external data source, follow the steps below to create Sage 50 UK external objects that reflect any changes in the data source. You will synchronize the definitions for the Sage 50 UK external objects with the definitions for Sage 50 UK tables.

1. Click the link for the external data source you created.
2. Click Validate and Sync.
3. Select the Sage 50 UK tables you want to work with as external objects.

Access Sage 50 UK Data as Salesforce Objects

After adding Sage 50 UK data as an external data source and syncing Sage 50 UK tables with Sage 50 UK 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 Sage 50 UK external objects alongside standard Salesforce objects:

• Create, read, update, and delete Sage 50 UK 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.
