Setup a REST Smartsheet Connection Manager

The REST Connection Manager is an SSIS connection manager component that can be used to establish connections with Smartsheet REST service to help facilitate Smartsheet data integration.

See Smartsheet REST Source Component  for how to retrieve data from Smartsheet & Smartsheet REST Destination Component for how to write to Smartsheet.

To add a new connection, right-click the Connection Manager area in your Visual Studio project, and choose "New Connection..." from the context menu. You will be prompted the "Add SSIS Connection Manager" window. Select the "REST (KingswaySoft)" item to add a new REST Connection Manager.

New SSIS Connection

Add SSIS REST Connection Manager

The REST Connection Manager contains 2 pages of configuration.

  • General
  • Advanced

General page

The General page allows you to specify connection properties and login credentials for Smartsheet REST service:

SSIS REST Smartsheet Connection Manager

Service Name

The REST service that will be connected to. 

API Throttle Rate

The API Throttle Rate will limit the number of requests that can be sent per second. 

Smartsheet Authentication

The Scope parameter indicates which parts of the Smartsheet user's account you'd like your app to be able to access.

Authentication Mode

The Authentication Mode that will be used to connect to Smartsheet.  Either API Token or OAuth.

Smartsheet Token Authentication
API Token

If you have an API Token that you would like to use, enter it in the API token field.

Smartsheet OAuth Authentication
Generate Token (In App)...

The Generate Token File (In App)... button completes the entire OAuth authentication process inside of the toolkit. All you need to do is login to the service endpoint and authorize our app to generate your token.

Generate Token (In Browser)...

The Generate Token File (In Browser)... button completes the OAuth authentication using your default browser. After you click this button simply follow the steps in the dialog to generate your token.

Path To Token File

After completing the OAuth process a token file must be saved that contains an OAuth token and an OAuth refresh token.  These tokens are used to authenticate SmartSheet requests and to get new tokens if the current tokens expire.

Token File Password

The Token File Password that can be used by the Rest Connection Manager to access the contents of the token file.

Test Connection

After all the connection information has been provided, you may click the "Test Connection" button to test if the user credentials entered can connect to the selected REST service.

REST Connection Manager - Advanced

Proxy Mode

Proxy Mode option allows you to specify how you want to configure the proxy server setting. There are three options available.

  • No Proxy
  • Auto-detect (Using system configured proxy)
  • Manual
Proxy Server

Using Proxy Server option allows you to specify the name of the proxy server for the connection.


The Port option allows you to specify the port number of the proxy server for the connection.

Username (Proxy Server Authentication)

Username option (under Proxy Server Authentication) allows you to specify the proxy user account.

Password (Proxy Server Authentication)

Password option (under Proxy Server Authentication) allows you to specify the proxy user's password.

Note: The Proxy Password is not included in the connection manager's ConnectionString property by default. This is by design for security reasons. However, you can include it in your ConnectionString if you want to parameterize your connection manager. The format would be ProxyPassword=myProxyPassword; (make sure you have a semicolon as the last character). It can be anywhere in the ConnectionString.


The number of seconds requests should wait before timing out.

Retry on Intermittent Errors

The retry on intermittent errors option determines if requests will be retried when there is an error. If this option is checked requests will be retried up to 3 times.
