Setup a REST Yammer Connection Manager

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

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

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 Settings

General page

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

SSIS REST Yammer Connection Manager

Service Name

The REST service that will be connected to.

Base URL

The URL of the Yammer’s REST API that the connection manager will connect to.

API Throttle Rate

The API Throttling Rate will limit the number of requests that can be sent per minute.

Client Id

The Client Id option allows you to specify the unique ID which identifies the application making the request. This can be created in Yammer Developer Center.

Client Secret

The Client Secret option allows you to specify the client secret belonging to your Yammer app, it is found in the details pane of the developer console.

Redirect Url

The Redirect Url option allows you to specify the Redirect Url to complete the authentication process.

Sign in using default web browser (Only available with OAuth Authorization Code authentication):

When this option is checked the Generate Token File button will open your default web browser in order to complete the OAuth authentication.

When this option is unchecked, the Generate Token File button will complete the entire OAuth authentication process inside of the toolkit.

Generate Token File
This button allows you to login to the service endpoint and authorize your app to generate a token.
Access Token

If you have an Access Token that you would like to use, enter it in the access token field. If you do not have a Yammer access token you can generate one by clicking the Generate Token button.

Show Token Button

If you need to see or copy the token in the 'Authentication Token' field click the 'Show Token' button to reveal the text of the token.

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.

Advanced Settings page

REST Connection Manager - Advanced

Proxy Mode

Proxy Mode option allows 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 a request 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.

Ignore Certificate Errors

This option can be used to ignore those SSL certificate errors when connecting to Yammer servers.

Warning: Enabling "Ignore Certificate Errors" option is generally NOT recommended, particularly for production instance. Unless there is a strong reason to believe the connection is secure - such as the network communication is only happening in an internal infrastructure, this option should be unchecked for best security.
