Pro Tip: Use the Portal Proxy

Instead of calling the dChat API directly, you can use the built-in portal proxy at /api/send-message. This keeps your Auth Bearer Token server-side and accepts JSON POST requests.

POST /api/send-message
Content-Type: application/json

{
  "sender_uuid": "your-uuid",
  "to": "919876543210",
  "type": "text",
  "body": "Hello from the portal proxy!"
}
