## Introduction
WhatsApp is the world's most widely used messaging app, with over 2 billion active users. By connecting your enterprise WhatsApp Business account to On-Chat, your team can manage customer conversations, run automated flows, send notifications, and handle support requests — all from a single, unified inbox. This guide walks you through connecting an existing enterprise WhatsApp account to On-Chat.

## Prerequisites
Before you begin, make sure you have:
- An approved **WhatsApp Business API** account (through Meta Business Manager)
- A verified **Facebook Business Manager** account
- A dedicated phone number approved for WhatsApp Business
- Admin access to your On-Chat workspace

## Step 1: Access your On-Chat channel settings
Log in to your On-Chat workspace. Navigate to **Settings → Channels** and click **Add Channel**. From the channel list, select **WhatsApp** under the Social Network Channels section.

## Step 2: Enter your WhatsApp Business credentials
On-Chat will prompt you for your WhatsApp Business API credentials. You will need your **Phone Number ID**, **WhatsApp Business Account ID**, and your **System User Access Token** from Meta Business Manager. Enter these values in the corresponding fields.

## Step 3: Configure the webhook
On-Chat will display a **Webhook URL** and a **Verify Token**. Copy these values and add them to your WhatsApp Business App configuration in the [Meta Developer Portal](https://developers.facebook.com). Navigate to your app → WhatsApp → Configuration → Webhook and paste the values.

## Step 4: Subscribe to webhook events
In the Meta Developer Portal, subscribe to the following webhook events under your WhatsApp integration: **messages**, **messaging_postbacks**, and **message_deliveries**. This ensures On-Chat receives all inbound messages and status updates.

## Step 5: Verify the connection in On-Chat
Return to On-Chat and click **Verify Connection**. If your credentials and webhook are configured correctly, the channel status will change to **Connected**.

## Step 6: Assign the channel to an inbox
Once connected, assign your WhatsApp channel to one or more On-Chat inboxes. Go to **Settings → Inboxes**, select the WhatsApp channel, and configure agent assignments, auto-reply messages, and business hours.

## Step 7: Send a test message
Using a personal WhatsApp account, send a message to your WhatsApp Business number. The message should appear in your On-Chat inbox within seconds. Reply from On-Chat to confirm two-way messaging is working.

## Best Practices
- Always get **opt-in consent** from contacts before messaging them on WhatsApp
- Use **message templates** for outbound notifications (required by WhatsApp policy for messages sent outside the 24-hour window)
- Set up **auto-replies** for off-hours in On-Chat's inbox settings
- Monitor your **message quality rating** in Meta Business Manager to maintain good delivery rates
