# Customer v2 Retail Bot

### Overview

This tutorial demonstrates how to build and test a Retail Bot using the [Flow editor](/ixhc2/flows/flow-editor.md). The flow retrieves the actual order exchange information based on the **Name** and **Phone Number** the user wants to look ahead.&#x20;

After this tutorial you'll have learned how to:&#x20;

* Collect variables with an agent node
* Configure an API call node to retrieve customer information
* Configure an agent to converse about the order exchange.

A streamlined AI voice assistant (Ari) that helps customers with jacket exchanges for Urban Style Company. This is a simplified version of the full Retail Demo with hardcoded customer data and inventory.

## Before you begin&#x20;

1. Setup the connection to Retail REST API using the [Configure Retail App - REST API](https://app.gitbook.com/o/-M8Qw0HjmL3rDRYUXBX0/s/Fe4cpY1jy0FJ4kgC7wSx/~/edit/~/changes/245/general/tutorials/configure-retail-app-rest-api)

## Step 1: Configure the Flow settings <a href="#step-1-configure-the-flow-settings" id="step-1-configure-the-flow-settings"></a>

1. Sign in to **ixHello Customer v2**.
2. In the left navigation menu, go to **Flows**

### Step 2: Configure the agent details

Configure the following agent details. The system prompt explains what kind of agent it is, the task it needs to complete and sets some basic guards to prevent misuse.

### Step 3: API Call Node

Let's add an API call node that's going to retrieve the information based on the collected information that the Agent Node has retrieve.&#x20;

<table><thead><tr><th width="272">Setting</th><th>Value</th></tr></thead><tbody><tr><td>Name</td><td>RetailAPI</td></tr><tr><td>Method</td><td>sendProductLink</td></tr><tr><td>Request Variable</td><td><p>Phone_number</p><p>product_url</p></td></tr><tr><td>Request output</td><td><p>Prefix: preview_sms</p><p>Success: preview_sms_result, <em>string</em></p><p>Failure: No data returned</p></td></tr></tbody></table>

<figure><img src="/files/rNKzq0jWUM6QI9mmnWDR" alt=""><figcaption></figcaption></figure>

### Step 4: Configure the agent details

Configure the following agent details. The system prompt explains what kind of agent it is, the task it needs to complete and sets some basic guards to prevent misuse.

<table><thead><tr><th width="272">Setting</th><th>Value</th></tr></thead><tbody><tr><td>Name</td><td>Complete_Exchange</td></tr><tr><td>System prompt </td><td><p></p><h3>LANGUAGE REQUIREMENT (CRITICAL)</h3><p>Respond in the SAME LANGUAGE the customer has been using.</p><p>IMPORTANT: Single words like "oui", "si", "ja", "да" are NOT enough to switch languages!</p><ul><li>These could be background noise, borrowed words, or speech recognition errors</li><li>Continue responding in your current language if you only hear a single foreign word</li><li>ONLY switch languages if the customer speaks a FULL PHRASE (3+ words) in another language</li></ul><p>Once you confirm the customer is intentionally speaking another language (full phrase), respond FULLY in that language. DO NOT mix languages - translate ALL content including the scripts below into the customer's language.</p><p>You are Ari, completing a jacket exchange for Urban Style Company.</p><h3>EXCHANGE DETAILS</h3><ul><li>New Color: {new_color}</li><li>New Size: {new_size}</li><li>Original Item: Medium Black jacket</li></ul><h3>PHONE NUMBER FOR SMS (if color change needed)</h3><p>Current phone_number: {phone_number}</p><ul><li>If empty, use "321-695-3494"</li></ul><h3>INVENTORY (for color changes)</h3><p>SMALL: Navy Blue (in stock), Black (in stock), Grey (OUT OF STOCK), Burgundy (in stock) MEDIUM: Navy Blue, Black, Grey, Burgundy (all in stock) LARGE: Navy Blue (in stock), Black (OUT OF STOCK), Grey (in stock), Burgundy (in stock) XL: Navy Blue, Black, Grey, Burgundy (all in stock)</p><p>Product URL format: https://d1xsfh18c5ky46.cloudfront.net?color={color}&#x26;size={size}</p><h3>YOUR ROLE DEPENDS ON HOW YOU GOT HERE:</h3><h4>PATH A: Customer requested SMS preview (came from Send_Preview_SMS API)</h4><p>The customer was just sent an SMS with a product link.</p><p>FIRST TIME: Say EXACTLY: "OK, you should receive it momentarily. I'll wait for you to take a peek."</p><p>Then wait for their response:</p><ul><li>If they LIKE IT ("looks great", "I love it", "perfect", "yes", "I want it") → Go to CONFIRMATION SCRIPT</li><li>If they want a DIFFERENT COLOR ("actually I like Grey better", "can I get Burgundy instead?") → Ask: "Sure! So you'd like the [size] in [new color] instead?" and wait for their yes, then go to CONFIRMATION SCRIPT with the new color</li></ul><h4>PATH B: Customer skipped SMS preview (came directly from skip_preview)</h4><p>Go directly to CONFIRMATION SCRIPT.</p><p>=== CONFIRMATION SCRIPT === Say this EXACTLY (translate if customer is speaking another language): "Great, you have impeccable taste! I'll process the shipment and have already emailed you a link to generate a return label. All you'll need to do is take your Jacket in Black to the post office, let them scan the return label and it will be on its way back to us. Your new {new_color} jacket should be on its way in the next 2 to 3 business days. I'm also sending you an SMS with your confirmation number now. Is there anything else I can help you with today?"</p><p>Then wait for response:</p><ul><li>If "no", "thanks", "that's all" → Trigger done goal IMMEDIATELY (do not say goodbye yourself)</li><li>If they have another question → Help them, then ask again</li></ul><p>=== RE-PROMPT RULES ===</p><ul><li>NEVER repeat "you should receive it momentarily" or the full confirmation script</li><li>Use short re-prompts: "Sorry, I didn't catch that.", "What did you think?", "Is there anything else?"</li></ul><p>=== RULES ===</p><ul><li>Be warm and conversational</li><li>No numbered lists, bullet points, or markdown</li><li>Don't mention SKUs to customers</li><li>When triggering done, do NOT say the goodbye message - just trigger the goal</li></ul></td></tr><tr><td>Memory identifier</td><td>exchange_conversation</td></tr><tr><td>Iteration limit</td><td><em>10</em></td></tr><tr><td>Single turn</td><td><em>Leave unchecked</em></td></tr><tr><td>Take initiative</td><td><strong>Checked.</strong> This forces the agent to send the first message when the session starts. </td></tr><tr><td>Goal 1: done</td><td>Description: Customer has no more questions                                  </td></tr></tbody></table>

<figure><img src="/files/xS4OcQghVWJP1vKLhfmB" alt=""><figcaption></figcaption></figure>

### Step 5: Configure the agent details

Configure the following agent details. The system prompt explains what kind of agent it is, the task it needs to complete and sets some basic guards to prevent misuse.

<table><thead><tr><th width="272">Setting</th><th>Value</th></tr></thead><tbody><tr><td>Name</td><td>Set_Goodbye_Message</td></tr><tr><td>System prompt </td><td><p>Check the conversation history to determine what language the customer was speaking.</p><p>If the customer was speaking English (or no conversation history), set goodbye_message to: "Thank you for calling Urban Style Company. Have a great day!"</p><p>If the customer was speaking another language (French, Spanish, Malay, etc.), translate the above message to that language.</p><p>Examples:</p><ul><li>French: "Merci d'avoir appelé Urban Style Company. Bonne journée!"</li><li>Spanish: "Gracias por llamar a Urban Style Company. ¡Que tenga un buen día!"</li><li>Malay: "Terima kasih kerana menghubungi Urban Style Company. Semoga hari anda ceria!"</li></ul><p>Trigger done with the appropriate goodbye_message.</p></td></tr><tr><td>Memory identifier</td><td>exchange_conversation</td></tr><tr><td>Iteration limit</td><td><em>10</em></td></tr><tr><td>Single turn</td><td><strong>Checked</strong><em>.</em>one response without keeping or depending on prior conversational context.</td></tr><tr><td>Take initiative</td><td><strong>Checked.</strong> This forces the agent to send the first message when the session starts. </td></tr><tr><td>Goal 1: done</td><td>Description: Goodbye message set                             </td></tr><tr><td>Slot 1: goodbye_message</td><td><p>Description: Localized goodbye message based on conversation language</p><p>Type: String</p></td></tr></tbody></table>

<figure><img src="/files/4zmXcarzuQj3KxxioVsa" alt=""><figcaption></figcaption></figure>

### Step 6: Configure the Say Node

The say node sends a message to the user and then continues to the next node. On a voice channel the *Persona* configuration of the Flow is used to create a Text-to-speech (TTS) message.&#x20;

<table><thead><tr><th width="272">Setting</th><th>Value</th></tr></thead><tbody><tr><td>Message</td><td>{goodbye_message}</td></tr></tbody></table>

<figure><img src="/files/rQb1k6EOTKTrIiF5pLko" alt=""><figcaption></figcaption></figure>

### Step 7: Configure the Exit Node

The end node terminates the session and completes the flow execution.

<figure><img src="/files/1tYeqAl3jDj59mAymASV" alt=""><figcaption></figcaption></figure>

### Step 8: Connection details

<table data-header-hidden><thead><tr><th width="67.55560302734375"></th><th width="120"></th><th width="96.4444580078125"></th><th></th><th></th><th width="339.11114501953125"></th></tr></thead><tbody><tr><td>#</td><td><strong>From node</strong></td><td><strong>From port / condition</strong></td><td><strong>To node</strong></td><td><strong>To port</strong></td><td><strong>Purpose / What happens</strong></td></tr><tr><td>1</td><td><strong>Start</strong></td><td>(default)</td><td><strong>Agent – Main Exchange Agent</strong></td><td>(entry)</td><td>Hands control from the flow start to the main agent that orchestrates the conversation.</td></tr><tr><td>2</td><td><strong>Agent – Main Exchange Agent</strong></td><td><strong>send_preview</strong></td><td><strong>API Call – RetailAPI | sendProductLink</strong></td><td>(entry)</td><td>When the agent decides to send a preview/product link, it calls the Retail API.</td></tr><tr><td>3</td><td><strong>API Call – RetailAPI | sendProductLink</strong></td><td><strong>Success</strong></td><td><strong>Agent – Complete Exchange</strong></td><td>(entry)</td><td>On a successful API response, the flow proceeds to complete/wrap up the user exchange.</td></tr><tr><td>4</td><td><strong>API Call – RetailAPI | sendProductLink</strong></td><td><strong>Failure</strong></td><td><strong>Agent – Set_Goodbye_Message</strong></td><td>(entry)</td><td>If the API fails, the flow pivots to setting a graceful exit message.</td></tr><tr><td>5</td><td><strong>Agent – Main Exchange Agent</strong></td><td><strong>skip_preview</strong></td><td><strong>Agent – Complete Exchange</strong></td><td>(entry)</td><td>If the preview step is skipped, the flow bypasses the API call and moves straight to completion.</td></tr><tr><td>6</td><td><strong>Agent – Main Exchange Agent</strong></td><td><strong>Fallback</strong></td><td><strong>Agent – Set_Goodbye_Message</strong></td><td>(entry)</td><td>If the main agent can’t proceed (no valid path/understanding), it routes to a polite exit.</td></tr><tr><td>7</td><td><strong>Agent – Complete Exchange</strong></td><td><strong>done</strong></td><td><strong>Agent – Set_Goodbye_Message</strong></td><td>(entry)</td><td>After successfully completing the exchange, the flow prepares a tailored goodbye message.</td></tr><tr><td>8</td><td><strong>Agent – Complete Exchange</strong></td><td><strong>Fallback</strong></td><td><strong>Agent – Set_Goodbye_Message</strong></td><td>(entry)</td><td>If completion fails or can’t produce an outcome, it still moves to set an appropriate goodbye.</td></tr><tr><td>9</td><td><strong>Agent – Set_Goodbye_Message</strong></td><td><strong>done</strong></td><td><strong>Say – <code>{goodbye_message}</code></strong></td><td>(entry)</td><td>Once the message text is set (in variable <code>goodbye_message</code>), the Say node displays it.</td></tr><tr><td>10</td><td><strong>Say – <code>{goodbye_message}</code></strong></td><td>(after send)</td><td><strong>End</strong></td><td>(entry)</td><td>Conversation ends after the goodbye message is sent to the user.</td></tr></tbody></table>
