The Logic Node provides a simpler experience to developers, primarily business users to use context variables and define complex transition conditions. Its two primary functions are:<\/p>\n

    \n
  1. Ability to manage variables and values of variables in the context object.<\/li>\n
  2. Ability to define nested transition conditions.<\/li>\n<\/ol>\n\r\n\t\t<\/div>\r\n\t<\/div>\r\n

    Add a Logic Node to the Dialog Task<\/span><\/h3>\n
      \n
    1. Open the dialog task in which you want to add the Logic node.<\/li>\n
    2. Click the <\/b>\"diydialogtaskplusicon\" icon next to the respective node.<\/li>\n
    3. Select Logic<\/b> > New logic node<\/strong>. You can also select an existing logic node from the available list.<\/li>\n
    4. The Logic window is displayed with the Component Properties<\/strong> tab selected by default.<\/li>\n<\/ol>\n\r\n\t\t<\/div>\r\n\t<\/div>\r\n

      Define Component Properties<\/span><\/h3>\n
        \n
      1. On the Component Properties<\/strong> tab, under the General Settings<\/strong> section, you can modify the Name<\/strong> and Display Name<\/strong>.<\/li>\n
      2. Use the Manage Context Variables<\/strong> section to set the context variables by entering a key-value pair.\u00a0Use the full path of the variable in the key<\/em> field i.e. context.BotUserSession.<variable_name>.<\/em><\/li>\n
      3. In the Variable Namespaces<\/strong> section (v8.0), associate the variable namespaces to execute this node and its transitions. This option is visible only when the variable namespace is enabled for the bot. You can go with the task level settings or customize it for this node. For more information, refer to Managing Namespace<\/a>.<\/li>\n<\/ol>\n\r\n\t\t<\/div>\r\n\t<\/div>\r\n

        Configure the Instance Properties<\/span><\/h3>\n

        Use the Instance Properties to define any user tags that you want to set.<\/p>\n

        Note:<\/b> The settings in the Instance Properties tab are specific to the current dialog task and do not reflect in other dialog tasks\u00a0that use this entity node.<\/div>\n
        <\/div>\n
          \n
        1. On the Logic window, click the Instance Properties<\/strong> tab.<\/li>\n
        2. Under the Custom<\/strong> Tags <\/strong>section, add tags to build custom profiles of your bot conversations. Click here for more<\/a><\/li>\n<\/ol>\n\r\n\t\t<\/div>\r\n\t<\/div>\r\n

          Configure the Connections Properties<\/span><\/h3>\n

          From the node\u2019s Connections<\/strong> tab, you can determine the node in the dialog task to execute next. You can write the conditional statements based on the values of any Entity or Context Objects in the dialog task, or you can use intents for transitions.
          \nTo setup Component Transitions, follow the below steps:<\/p>\n

            \n
          1. On the Logic window, click the Connections<\/strong> tab.<\/li>\n
          2. Under the Connection Rules<\/strong> section, you can select a node from the Default<\/strong> drop-down list.<\/li>\n
          3. To configure a conditional flow, click Add IF<\/b>.<\/li>\n
          4. Configure the conditional expression based on one of the following criteria:\n
