How It Works

Businesses use the Telebuzz REST API to connect their applications, CRMs, and backend systems to a unified messaging platform.

Authenticate using your API key and send requests to our secure HTTPS endpoints. With standard HTTP methods like GET and POST, you can send messages, check delivery status, and manage contacts effortlessly. For real-time two-way communication, receive inbound messages and delivery updates through webhooks.

Send messages

Send messages by making a POST request to the messaging endpoint with the recipient number, preferred channel (SMS, WhatsApp, or RCS), and message content. Instantly receive a message ID and status confirmation.

Receive events

Set up webhook URLs to automatically receive delivery reports, read receipts, and inbound messages. Use the same API to respond and manage conversations in real time.
