# Using External APIs in waatee FlowBuilder with Dynamic List Display

Integrating external APIs into your chatbot flow allows your waatee bots to fetch real-time data and interact seamlessly with third-party systems like eCommerce platforms, CRMs, and more. This guide walks you through building a flow that fetches dynamic product data using an HTTP API and displays it inside WhatsApp through a list picker.

## **🔍 Introduction**

waatee's FlowBuilder allows you to:

- Retrieve data from external APIs.
- Display real-time product lists or dynamic options.
- Let users interact through WhatsApp with structured list replies.
- Automatically respond using selected data fields from JSON.

In this documentation, we’ll build a flow using an HTTP API GET call that shows a dynamic list of products and handles selection with response confirmation.

## **🛠 Step-by-Step Instructions**

### **1. Create the Bot Flow with a Trigger Word**

- From **Bot Reply**, click **Create**.
- Assign a **title** (e.g., HTTP API) and a **trigger word** like httptest.

### **2. Add HTTP API Call Element**

- Drag the **HTTP API** element next in the flow.
- Choose a pre-configured **GET** request (e.g., Test Http : GET).
- This fetches a list of products in JSON format.

### **3. Add Interactive Element**

- From the top bar, choose the **Interactive**
- Enter a message like:
  **Text**: This is a HTTP API Test
   **Button Label**: Choose One...

### **4. Configure List Picker**

- From the next step, choose **List Messages** and configure:

  - **Quick Reply Name**: Choose Product
  - **Section Name**: Pick One

### **5. Configure Row Element**

- Keep only **one row** and delete the other two (as per your need).
- Set Row Generation Method to **Dynamic**.
- Use the following configuration:

| **Field** | **Value** |
| --- | --- |
| Custom Field for Dynamic Rows | #Product_Name# |
| Key/Index for Row Title | product_list |
| Row Description Format | #Product_Name->price# - #Product_Name->orderID# |
| Save Selection to Custom Field | Product_Name |
| Key/Index for Saved Value | purchase_link |

### **6. Add Text Message for Selection Feedback**

- Add a **Text** element to reply after a selection.
- Use a message like:
  You can buy our product from #selected_product#

### **7. Save and Test the Bot**

- Click the **Save**
- Go to your connected WhatsApp.
- Type the **trigger word** httptest.

You will receive an interactive list with products fetched dynamically via API. Upon selection, the bot responds with your predefined message using the selected value.

## **💡 Use Case Examples**

- **Show WooCommerce Product Lists** directly inside WhatsApp.
- **Display custom dynamic options** like event tickets, services, or categories from any API.
- **Verify orders** and display related tracking info or invoice links from your backend.

## **✅ Conclusion**

This flow demonstrates how easily you can bring **dynamic external content into WhatsApp** using waatee. With just a few steps, your chatbot can:

- Fetch JSON from any API.
- Parse and display it as a WhatsApp list.
- Capture and use selected values for personalized responses.
