Built for people who read the docs first
Predictable REST, a streaming WebSocket, HMAC-signed webhooks, idempotency keys, and an MCP server so your agents can drive WhatsApp directly. Read the docs, ship in an afternoon.
Inside developer api
REST API
Resource-oriented endpoints, cursor pagination, idempotency keys, and consistent error envelopes.
WebSocket stream
Subscribe to message, status, session, and presence events with automatic reconnect and replay from cursor.
Signed webhooks
HMAC-SHA256 signatures, timestamp tolerance, automatic retries with exponential backoff, and a delivery log.
Testing console
Fire sample payloads at your endpoint, inspect request and response, and replay any historical delivery.
MCP server
Your AI agents, such as ChatGPT, Claude, or custom bots, get full access to Beacon through MCP. They can send and receive messages, manage contacts, run campaigns, build automations, handle templates, and update settings. No custom integration needed.
