Step 2: Add Chat Widget

html
<!-- Add to your website -->
<script>
  (function(d,t) {
    var BASE_URL="https://chat.example.com";
    var g=d.createElement(t),s=d.getElementsByTagName(t)[0];
    g.src=BASE_URL+"/packs/js/sdk.js";
    g.defer = true;
    g.async = true;
    s.parentNode.insertBefore(g,s);
    g.onload=function(){
      window.chatwootSDK.run({
        websiteToken: 'YOUR_WEBSITE_TOKEN',
        baseUrl: BASE_URL
      })
    }
  })(document,"script");
</script>

Step 3: API Integration

typescript
// lib/chatwoot.ts — Create contacts and conversations via API
const CHATWOOT_URL = 'https://chat.example.com'
const CHATWOOT_TOKEN = process.env.CHATWOOT_API_TOKEN!

// Create contact when user signs up
await fetch(`${CHATWOOT_URL}/api/v1/accounts/1/contacts`, {
  method: 'POST',
  headers: {
    'Content-Type': 'application/json',
    api_access_token: CHATWOOT_TOKEN,
  },
  body: JSON.stringify({
    name: 'John Doe',
    email: 'john@example.com',
    custom_attributes: { plan: 'pro', mrr: 49 },
  }),
})
