REST API
Integrate messaging into your applications with our secure, well-documented REST API. Send and receive WhatsApp, SMS, and RCS messages from any system with simple HTTP requests.
How It Works
Businesses use the Bluemessaggio REST API to connect their applications, CRMs, and backend systems to a single messaging platform.
Authenticate with your API key, then send requests to our HTTPS endpoints. Use standard HTTP methods (GET, POST) to send messages, check status, and manage contacts. Receive inbound messages and delivery events via webhooks for real-time two-way communication.
Send messages
POST to the send endpoint with recipient, channel (SMS, WhatsApp, RCS), and content. Get immediate message ID and status.
Receive events
Configure webhook URLs to receive delivery reports, read receipts, and inbound messages. Respond via the same API.
