When building a bot, you can add one of the following actions to a node in the bot:

• Link to an Existing Node: Links a node to an existing node in the bot. This option simplifies the building of a bot by avoiding duplicate nodes in the bot. 

  Suppose that you want a customer to provide their email address when they choose to sign up for a service, request a demonstration, or submit a query. Instead of adding the Email Address node three times (that is, to the three options of the Multiple Choice node), you can add the Email Address node to any one option of the Multiple Choice node and link the remaining options to the same Email Address node. In the following bot, the Email Address node is added to the Sign up option of the Multiple Choice node. The Request a demo and Submit a query options of the Multiple Choice node are linked to the same Email Address node by using the Link to an Existing Node action.

  
  

• Redirect to an External URL: Links an option of the Multiple Choice node to a web page. When a customer selects the option, the specified web page appears.
