## Prerequisites
- An active Zenvia account with a WhatsApp number provisioned
- Your Zenvia **API token** or **API key** from the Zenvia dashboard
- The WhatsApp phone number registered in Zenvia
- Admin access to your On-Chat workspace

## Step 1: Retrieve your Zenvia API credentials
Log in to your Zenvia platform account and navigate to **Developer Tools** or **API Configuration**. Copy your **API key** and note the WhatsApp number associated with it.

## Step 2: Open On-Chat channel settings
In On-Chat go to **Settings → Channels → Add Channel** and select **Zenvia WhatsApp** from the Social Network Channels list.

## Step 3: Enter your Zenvia credentials
In On-Chat's setup form, paste your Zenvia API key and enter your WhatsApp phone number in international format (e.g. +5511999999999). Click **Save Channel**.

## Step 4: Configure the webhook in Zenvia
On-Chat will provide a **Webhook URL**. Log back into your Zenvia dashboard and navigate to your WhatsApp channel settings. Paste the On-Chat webhook URL as the inbound message endpoint. Zenvia will POST all incoming WhatsApp messages to this URL.

## Step 5: Assign the channel to an inbox
In On-Chat, go to **Settings → Inboxes** and assign your Zenvia WhatsApp channel to an inbox. Set up auto-welcome messages, working hours, and agent routing.

## Step 6: Test the integration
Send a WhatsApp message to your Zenvia number from a personal phone. It should appear in your On-Chat inbox. Reply to verify outbound messaging is working.

## Best Practices
- Configure Zenvia's sandbox environment first to test your integration before going live
- Use On-Chat's automation flows to handle FAQs and reduce manual agent workload
- Tag conversations with On-Chat labels (e.g. Sales, Support, Billing) for easy filtering and reporting
- Review Zenvia's message delivery reports alongside On-Chat's conversation analytics for full visibility
