An API you don't have to fight
If you're the technical co-founder who ends up owning the messaging stack, this is for you. Predictable endpoints, real event streams, idempotency, and sandbox sessions so you can test without burning a production number.
What usually breaks
Most WhatsApp APIs are wrappers
Beacon exposes sessions, messages, contacts, templates, and events as first-class resources.
Webhooks you can't trust
HMAC signatures, timestamp tolerance, retries with backoff, and a replayable delivery log.
No way to test safely
Sandbox sessions and a webhook console that fires real payload shapes at your endpoint.
Agents need tools, not docs
MCP (Model Context Protocol) lets your AI agents call any Beacon operation as a tool, including messaging, contacts, campaigns, automations, templates, and settings. No glue code.
How it runs on Beacon
Get a key
Scoped API keys with per-key rate limits and environment separation.
Connect a session
QR login via API, session health events over the WebSocket.
Wire your webhook
Verify the signature, replay historical deliveries while you build.
Ship
Comprehensive API documentation with interactive examples and a webhook testing console.
