Connect Your First Channel

Before you start

You'll need credentials from the messaging provider. DMHub supports:

• WhatsApp Business API via Twilio or Meta directly
• SMS via Twilio
• Email via Resend
• Web Widget — no credentials needed, generates a script tag

Step 1: Go to channel settings

Navigate to /settings/channels. You'll see all available channel types.

Step 2: Choose your channel

WhatsApp (fastest path)

1. Click WhatsApp → Connect via Twilio
2. Paste your Twilio Account SID and Auth Token — found at console.twilio.com
3. Paste your Twilio WhatsApp sender number (format: whatsapp:+1XXXXXXXXXX)
4. Click Save & Test
5. Send a WhatsApp message to that number — it should appear in your inbox within seconds

SMS

1. Click SMS → Connect via Twilio
2. Paste your Twilio Account SID, Auth Token, and SMS-enabled phone number
3. DMHub auto-configures the webhook on your Twilio number
4. Click Save & Test

Email

1. Click Email → Connect via Resend
2. Enter your Resend API key and the "from" address you want to use
3. Configure your DNS records (Resend provides the values)
4. Click Save & Test

Web Widget

1. Click Web Widget → Generate
2. Copy the <script> tag
3. Paste it before </body> on your website:

<script
  src="https://www.dmhub.ai/widget.js"
  data-inbox="your-inbox-id"
  async>
</script>

Step 3: Verify the connection

Send a test message through your connected channel. Check the /inbox — you should see the conversation appear within 5 seconds.

Troubleshooting

If the test message doesn't arrive, check:

• Webhook URL is set correctly on your provider's dashboard
• Credentials are valid (try a fresh copy-paste)
• See Why are my messages failing? for detailed diagnostics
