## Prerequisites
- An active DartMedia account with SMS API access
- DartMedia API credentials (username, password, or API key)
- On-Chat account with admin access
- A DartMedia sender ID or virtual number for two-way SMS
- Webhook/callback URL configuration access in DartMedia

## Step 1: Obtain DartMedia API Credentials
Log in to your DartMedia account and navigate to the API settings or developer section. Copy your **API Key** or **Username and Password** that On-Chat will use to send outbound SMS messages via DartMedia's gateway.

## Step 2: Configure Your Sender ID
In DartMedia, set up your sender ID or virtual number for two-way SMS messaging. This is the identifier your Indonesian customers will see when they receive your SMS messages and the number they can reply to.

## Step 3: Create an SMS Inbox in On-Chat
In On-Chat, go to **Settings** → **Inboxes** → **New Inbox** and select **SMS**. Choose **DartMedia** as the provider. Enter your API credentials and sender ID. Save to generate the On-Chat webhook URL for inbound messages.

## Step 4: Configure the Inbound SMS Webhook
In your DartMedia account, find the inbound message callback or delivery report settings. Set the inbound SMS URL to your On-Chat webhook endpoint. DartMedia will forward all incoming SMS messages to this URL, routing them into your On-Chat inbox.

## Step 5: Add Agents to Your DartMedia Inbox
In On-Chat, go to **Settings** → **Inboxes** → select your DartMedia inbox → **Collaborators**. Add agents who will manage Indonesian customer SMS conversations. Set up routing rules to distribute conversations among available agents.

## Step 6: Test the Integration
Send a test SMS to your DartMedia number from an Indonesian mobile number. Verify it appears in your On-Chat inbox. Reply from an agent and confirm the message is delivered back to the customer's mobile device.

## Best Practices
- Use Bahasa Indonesia in canned responses for local customer communications
- Monitor SMS delivery rates across Indonesian carriers (Telkomsel, Indosat, XL)
- Use On-Chat automation to send immediate auto-replies during peak hours
- Track SMS volume trends using On-Chat and DartMedia analytics dashboards
