A multi-tenant WhatsApp API platform. Link one or more WhatsApp numbers, send and receive messages through a REST API, and get real-time delivery through webhooks — all from one simple dashboard.

- Isolated sessions — every linked WhatsApp number runs in its own container. One number's crash, rate limit, or ban risk never touches another.
- Simple REST API — send a message with one authenticated HTTP call. No browser automation, no fragile Puppeteer scripts to babysit.
- Real-time webhooks — get notified the moment a message arrives or a session's status changes, signed with your own secret so you can verify authenticity.
- A real dashboard — see your chat history, manage sessions, run bulk campaigns, and track usage against your plan, all in one place.
- n8n-native — the official
n8n-nodes-simplewacommunity node lets you build WhatsApp chatbots, AI agents, and automations visually, no code required.
Generate an API key from your dashboard Settings page, then send your first message:
curl -X POST https://simplewa.com/api/saas/gateway/sessions/{sessionId}/message \
-H "X-API-Key: swa_live_..." \
-H "Content-Type: application/json" \
-d '{"to": "15551234567", "body": "Hello from SimpleWA!"}'That's it — no QR-scanning script to maintain, no dedicated server to run. See docs/quickstart.md for the full walkthrough, including how to create and connect a session.
