  5. Service Node

Service Node

The Service Node is a component type in a dialog task that you can use to add an API service to make REST or SOAP requests to third-party web services. You can use this node when you have the parameters needed for the API request using an entity or other nodes to capture the user input.

Add the Node

Service Nodes can only be added as part of a Bot Action node. Therefore, before you can add a Service Node, you need to add a Bot Action node. Read more about Bot Action Nodes.

Note: Post v9.0 of the XO )Platform, the Service node is categorized under the Bot Action node. For details on the Bot Action node, click here.

Keeping this in mind, the setup of a Service node in a dialog task involves the following steps:

  1. Open the dialog task to add the Service node.
  2. Create and/or expand a Bot Action node.
  3. Add a Service node in the designated place. For steps related to adding nodes, refer here.
  4. The Service window is displayed with the Component Properties tab selected by default.
  5. To connect a Service node to a node outside of its containing Bot Action node, please read our article about the Bot Action Node.


Configure the Node

Component Properties

Note: All changes made to the Component Properties tab will affect all instances of the Service node, across Dialog Tasks. 

 

To configure the Component Properties tab, please follow the steps below:

  1. On the Component Properties tab, under the General Settings section, enter the Name and Display Name of your Service node. 
  2. Choose a Service Type from the drop-down list:
    1. Custom Service – Define an API request to a third-party web service. This is the default setting.
    2. HTML to Image – Define HTML to render as an image using JavaScript. For example, to compose HTML or the value of a key in a web service response that contains HTML markup as a string that you want to convert to an image.
    3. URL to Image – Define a web page URL to load to render an image.
    4. Custom Authentication Service – Define a URL to a third-party application that provides the authentication services necessary for the task flow. Learn more.
    5. Alert Subscription Service – Define contextually relevant alerts to be sent proactively to the user as a part of the dialog journey.
    6. Data Service – Define CRUD operations to query and manipulate the data for any given data table/table view.
  3. Based on the service type selected, select the Type/Sub Type from the respective drop-down lists or Auth URL.
  4. Under the Request Definition section, click Define Request.
  5. The Define Request for < ServiceXXXX > dialog is displayed, as shown in the following illustration.

    Note: In the case of a Custom Authentication Service, the Request Definition section does not apply and you can see a Response

    Depending on the Service Type selected, refer to one of the following sections in this topic:

    1. Defining a Custom Service
    2. Defining a URL to Convert to Image
    3. Defining HTML to Convert to Image
    4. Defining Alert Subscription Service
    5. Defining Data Service
  6. Under Advanced Controls, configure the Timeout for terminating the service call. You can configure this value between 1 Second and 20 Seconds. The default value is 5 Seconds. .
  7. In the Variable Namespaces section, associate the variable namespaces to execute this node and its transitions. This option is visible only when the Variable Namespace is enabled for the VA. You can go with the task level settings or customize it for this node. For more information, refer to Managing Namespace.

Instance Properties

Note: The settings in the Instance Properties tab are specific to the current dialog task and do not reflect in other dialog tasks that use this node.

 

Use the Instance Properties to define any user tags that you want to set.

  1. On the Service node properties panel, click the Instance Properties tab.
  2. Under the Custom Tags section, add tags to build custom profiles of your VA’s conversations. Click here for more.


Connections Properties

Since they are contained within Bot Action nodes, Service nodes cannot be connected on their own to any other nodes outside the Bot Action node to which they belong. Connections can only be made with nodes contained within the same Bot Action node. 

From the node’s Connection Properties tab, you can configure the following:

  • Service Node Connections: The node within the Bot Action to execute next, after the Service node runs. 
  • Bot Action Connections, where you can update the node to trigger after the Bot Action group is executed. Updates made here will apply to all nodes within the same Bot Action. 

For both connection types you can write conditional statements based on the values of any Entity or Context Objects in the dialog task, or you can use Intents for transitions. 

Note: The conditions configured here are applicable only for this instance and will not affect this node when being used in any other dialog.

 

To set up node connection conditions, please follow the steps outlined in Adding IF-Else Conditions to Node Connections. 


Service Types

You can define the Service Type as:

  • Custom Service – Define an API request to a third-party web service. This is the default setting.
  • HTML to Image – Define HTML to render as an image using JavaScript. For example, to compose HTML or the value of a key in a web service response that contains HTML markup as a string that you want to convert to an image.
  • URL to Image – Define a web page URL to load to render an image.
  • Custom Authentication Service – Define a URL to a third-party application that provides the authentication services necessary for the task flow.
  • Alert Subscription Service – Define contextually relevant alerts to be sent proactively to the user as a part of the dialog journey.
  • Data Table Service – Define CRUD operations to query and manipulate the data for any given data table/table view assigned to the Virtual Assistant.

Define a Custom Service

  1. When you select Custom Service in the Service Type, then in the Sub-Type field, select one of the options:
    1. REST – The API web service is using REST services.
    2. SOAP – The API web service is using SOAP services.
  2. In the Request Definition section, click Define Request to specify the settings for the web service type.
  3. The Define Request for < Service Node Name > dialog is displayed as shown in the following illustration.
  4. In the Request URL field, in the first field, select the HTTP method used for the request. You can select:
    1. POST – Used to send data to the server. For example, customer information, file upload, and so forth using HTML forms.
    2. PUT – Replaces the content of the target resource with the content sent.
    3. PATCH – Appends the content of an existing target resource with the content sent.
    4. DELETE – Deletes the content of an existing target resource.
    5. GET – Returns the content of an existing target resource
  5. In the second field of the Request URL, specify the URL for the dialog task response to process at Kore.ai. For example, http://koremessenger.com/postURL. Add query or path parameters as part of the URL, if required. To use entity node values as parameters, use the following syntax for accessing the Context object: https://myDomain.com/{{context.entities.topic}} for the context.entities.topic. You must use the double brackets {{ context.object }}. For more information, refer to Context Object.
    1. Optionally, click Show Advanced, and select
      1. Yes in the Access Using A Connector field if access for Kore.ai assistants is using the Kore.ai connector agent. For more information, refer to Using the Kore.ai Connector.

    2. In the Auth tab, select the type of authorization needed for this service node call, or define a new authorization type if needed. For more information, refer to Setting Up Authentication.
    3. In the Headers tab, specify the headers as key/value pairs if required to access the specified request URL.  Authentication headers are auto-generated based on the authorization type specified on the Auth tab. You need to define any other standard headers. For example, Content-type, Accept, or any custom headers. Headers defined here are only applicable to this service node.
    4. In the Body tab, select the body content type. You can select:
      1. application/x-www-form-urlencoded – Also known as Multipart/Form-data, which is an encoding type that allows files to be sent through an HTTP POST request method if you want to allow a user to upload a file from a form. You can add key/value pairs that are encoded by the XO Platform.
      2. application/json – Use JSON to transmit data between the Kore.ai servers and your VA’s web application. Any JSON is sent with the request without any processing.
      3. application/xml – For SOAP services, pass XML payload using POST methods. You can pass entity node values as part of the XML, using the following syntax for accessing the Context object: https://myDomain.com/{{context.entities.topic}} for the context.entities.topic. You must use the double brackets {{ context.object }}. For more information, refer to Context Object.
    5. In the Test Request tab, click Test to optionally send your API request URL using the specified Auth type, HTTP headers, and body parameters, if defined. The response is displayed in the text area. Click Save as Sample Response to save the test response as the sample response for this node.

*/
$(function() {
$("#print-button").on("click", function() {
  var table = $("#table1"),
      tableWidth = table.outerWidth(),
      pageWidth = 600,
      pageCount = Math.ceil(tableWidth / pageWidth),
      printWrap = $("<div></div>").insertAfter(table),
      i,
      printPage;
  for (i = 0; i < pageCount; i++) {
     printPage = $("<div></div>").css({
         "overflow": "hidden",
         "width": pageWidth,
         "page-break-before": i === 0 ? "auto" : "always"
       }).appendTo(printWrap);
  table.clone().removeAttr("id").appendTo(printPage).css({
     "position": "relative",
     "left": -i * pageWidth
    });
  }
table.hide();
$(this).prop("disabled", true);
});
});
</script>
</body>
</html>

 

The preceding HTML example, when table rows are added into the example, can render the following image to an end-user.


Define an Alert Subscription Service

You can now automatically subscribe your users to send contextually relevant alerts as part of the dialog journey. For example, a person booking a flight ticket for a specific date is auto-subscribed to get regular updates on the weather forecast for the destination city.

To set up an alert subscription service, follow the below steps:

  1. Open the Component Properties tab of the service node to which you want to associate the alert.
  2. Under the General Settings section, select Auto Subscription Service from the Service Type drop-down list.
  3. Click Define Request.
    Note: To create an alert subscription service, you must base it on an existing alert task. Users are auto-subscribed to the alert task on reaching the associated service node in the dialog.
  4. On the Smart/Automatic Alerts dialog box, select an alert task from the Choose Alert drop-down list. The list consists of only the published alert tasks related to your VA.
  5. Enter the necessary information as explained below.

Alert Subscription (Smart Alert) Configurations

In a typical alert setup, the alert parameters, filters, and other necessary details are entered by the users. Since this is an auto-subscription for alerts, you need to configure those details as a developer.

Alert Parameters

These vary according to the alert you select. Provide the default parameter values to use for the Alert Subscription service.

In this example, the parameters defined for the alert are Topic Name and News Region. Since the idea is to send weather forecasts to the user for the destination city, you can set the parameter values as Weather Forecast and context.entity.destinationcity respectively.

Filters

These vary according to the alert you select. Provide the filter criteria to use for the Alert Subscription service.

Alert Frequency

Provide the frequency to send alert notifications. You need to select a Scheme, Frequency, and Time Frame.

  1. From the Select Scheme drop-down list, select daily, weekday, or weekend, depending on when you want to send the alert.
  2. From the Select Frequency drop-down list, select Every if you want to send multiple alerts at regular intervals of time in a day or select at to send one alert at a specific time of the day.
  3. From the Select Time drop-down list, select an interval time value or a time of the day, depending on the frequency value chosen above.

For example, Daily At 6 a.m. means that an alert is sent to the user every day at 6 a.m.

Smart Alert Expiry

Configure when to expire sending alerts to the users from one of the following options:

  1. Duration: Stops sending notification after the entered number of days from the date of subscription.
  2. Number of Notifications: Stops sending alerts after an entered number of notifications are sent.

Alert Upgrades

Define the expected behavior of this alert if an upgraded version of the underlying alert task (the published alert that you have selected at the beginning) is published.

  1. Remove Existing Instances – All existing subscriptions of this smart alert are removed and users will no longer receive notifications. Users are auto-subscribed to the upgraded alert task only when they execute the dialog and reach the service node in the dialog journey.
  2. Allow Users To Manually Upgrade Subscription – Users will receive an upgrade notification on the selected channel which is a link that guides them through to upgrade their auto-subscription. If the upgrade is successful, the user will receive a success notification.

Define a Data Service

  1. When you select Data Service in the Service Type, the Type setting provides two options:
    1. Table – choose this option to perform CRUD operations on the data table.
    2. View – choose this option to fetch data from a table view.
      Note: Your VA should have permission to access the table/view. The owner of the table/view has to grant this permission, click here for how.
  2. In the Request Definition section, click Define Request to specify the operation you want to perform. Click here for details.
