# WhatsApp Chat API

## Overview

QuickReply.ai offers a native AI builder (chatbot builder) that covers most use cases efficiently. For typical needs, this built-in tool provides an easy-to-use and effective solution. The WhatsApp Chat API should be used primarily for scenarios requiring a custom proprietary chatbot with specific functionalities that cannot be achieved with the native builder. This can also be used if you wish to integrate a Generative AI based chatbot on to WhatsApp channel over QuickReply.ai

***

## How It Works

* **Disable AI Builder (chatbot builder)**
  1. Firstly, you will need to disable the AI builder.
  2. To disable AI builder, you can delete all nodes from these playbooks - <mark style="color:green;">**`Default`**</mark>, <mark style="color:green;">**`Fallback`**</mark> and <mark style="color:green;">**`Transfer`**</mark><mark style="color:green;">.</mark> In each of the playbooks, add a <mark style="color:red;">**`End`**</mark> node at the start.
  3. Alternatively you can write to <help@quickreply.ai> get the AI Builder disabled.
* **Receiving Messages:**
  * Incoming messages from users are received through a webhook configured to handle these events.
* **Sending Messages:**
  * To send a message to a WhatsApp user, make a POST request to the Send Message endpoint with the required message details.
* **Handling Message Status Updates:**
  * Track the status of sent messages (e.g., delivered, read) via a webhook that provides real-time updates.

## Important Notes

* If you want your system to generate responses to incoming messages, you can ignore message events for messages not sent by you via API.
* If you are using GenAI/LLM to generate responses, you might need message history that you have to maintain on your own.
