Orchestration Enhancement: Lex NLP Bot Integration

iX Hello is a no-code AI assistant platform by Concentrix that enables businesses to create multimodal, customer-facing bots quickly.

It supports intent-based orchestration, meaning you can design bots that route conversations across multiple skills or workflows based on user intent.

Overview

It refers to intents that act as a controller, orchestrating multiple sub-intents or workflows. Instead of a single response, these intents trigger a sequence of actions (e.g., fetching data from CRM, confirming details, updating backend).

Useful for complex journeys like:

• Order management (check status → update → notify)

• Appointment booking (validate availability → confirm → send reminder)

• Multi-step troubleshooting flows.

How to create intent-based Orchestration in iX Hello

Prerequisites

Before commencing bot creation, ensure the following prerequisites are met:

• Access to iX Hello Studio Mode.

• Familiarity with basic iX Hello navigation.

• Basic knowledge of RESTful API principles and JSON format for handling the data returned by the API.

• Use the below NLP bot links to create a custom app without using the Orchestration step

  • To Create a Basic NLP bot, refer to this

  • To Create the connection, refer to this, to publish on lex refer to this

Note : Use the below steps to create Intent using Orchestartion

Let's create an Intent

Navigate to the ‘Intents’ tab and click on the ‘Create New Intent’ button.

Create Design

Once the Intent is created, click on the Action and choose Design.

Which Open the intent design canvas, where you can define the orchestration flow (e.g., steps, API calls, conditions).

You will land on Orchestration Intent Design Canvas. It’s where you visually build the workflow for an orchestration-type intent.

Here’s what each element means:

• Start Node:

  • Entry point of the orchestration flow. Every design begins here.

• Method Node:

  • Represents a function or API call.

  • Used to fetch data, update records, or perform backend operations.

• Agent Node:

This node is not available for the NLP applications

• Get Slot Node:

  • Captures specific user input (e.g., email, phone number).

  • Essential for gathering required parameters before calling APIs.

• Say Text Node:

  • Sends a response message to the user.

  • Can display dynamic data from previous steps.

• Exit Node:

  • Marks the End of the orchestration flow.

• Connector Type : Flowchart / Straight Lines / Curve

  • Defines how steps are visually connected in the canvas.

  • Flowchart is the default for clear branching logic.

Here you can see the detailed explanations with the screenshots on the above-mentioned elements:

Start Node:

The start node is the start point of a flow; the processing of each session starts here. There needs to be exactly one start node in each flow.

Method Node:

• Title: You can rename this to something meaningful (e.g., FetchContactDetails).

• Data source Dropdown: This is where you select or define the API or backend system you want to connect to. The “+” icon lets you add a new data source by navigating to the method screen of the custom app, and the refresh icon reloads available sources.

• Data Source Method Dropdown: After selecting a data source, this field specifies which method or endpoint to call (e.g., GET /contacts, POST /updateContact). Again, “+” adds a new method by navigating to the method screen of the custom app, and refresh updates the list.

• Buttons:

  • Close: Exit without saving changes.

  • Delete: Remove this Method node from the flow.

  

Get Slot Node:

• Represents a step in the orchestration flow where the bot collects a specific piece of information from the user (called a “slot”).

• Message/Prompt: This is the question or prompt the bot will ask the user to capture the required information.

• Slot: The variable name where the captured value will be stored.

Say Text Node:

• Represents a step in the orchestration flow where the bot sends a message back to the user.

• Message/Prompt: This is the text the bot will display to the user at this step. It can be static (e.g., “Your request is complete.”) or dynamic (e.g., “Your contact details are: {{contact Info}}” using variables from previous steps).

• Often placed after a Method node (API call) to show the retrieved data or after a Get Slot node to confirm input.

Exit Node:

• Represents the end point of the orchestration flow. When the bot reaches this node, the conversation or the current process is terminated.

• Message/Prompt: This is an optional closing message the bot will display before ending the flow. Example: “Thank you for using our service. Goodbye!”

• It can also provide a final message to confirm completion or politely end the interaction.

Create Intent Orchestration

Get Slot: Setup of the specific Slot for the Intent

Settings	Description
Title	Person
Message/Prompt	Please provide the name of the person whose contact number you want to find.
Slot (Drop-Down)	Person (When interacting with intents, you expect inputs from the users. Those inputs are mapped to slots. You need to capture those inputs for processing the intent.)

Click: Close

Method: Setup of the specific Method for the Intent

Settings	Description
Title	GetContactMethod
Data Source (Drop-Down)	Rest API DS
Data Source Method (Drop-Down)	GetContactMethod

Say Text: Setup of the specific Say Text for the instance Contact Found

To show how the connections work, we created a dummy session variable

Settings	Description
Title	Contact Found
Message/Prompt	The contact of the {{Person}} is found.

Say Text: Setup of the specific Say Text for the instance Contact Not Found

Settings	Description
Title	Contact Not Found
Message/Prompt	The contact of the {{Person}} is not available in our database.

Connection Detail: Contact Found

Settings	Description
Title	Contact Found
Message/Prompt	Contact Found
Type (Drop-Down)	Conditional
Priority	1
Conditions	Slot/Variable: {{Session.Phone}}, Operator: Not Equals, Value : Empty

Connection Detail: Contact Not Found

Settings	Description
Title	Contact Not Found
Message/Prompt	Contact Not Found
Type (Drop-Down)	Conditional
Priority	1
Conditions	Slot/Variable: {{Session.Phone}}, Operator: Equals, Value: Empty

Exit: The Exit node terminates the session and completes the flow execution

Settings	Description
Title	Exit
Message/Prompt	Thanks for contacting and have a nice day!
