Send
Send messages from your stack — Node, Python, PHP, n8n, anything that speaks HTTP.
One Bearer token. Four endpoints. Webhooks signed with HMAC SHA-256. No SDK lock-in.
Text & media in one call
Send text, images, videos, audio, and documents through the same Bearer-authenticated POST. No template pre-approval, no business profile.
Webhooks with retry built-in
Receive sent/failed events on your URL, signed with HMAC SHA-256. Exponential retry on delivery failure, auto-disable after 5 strikes.
Audit, logs & stats
Every API call is logged. Dashboard shows messages/day, error rate, session status. Full visibility from the moment you deploy.
AI-native
AI-native. The first WhatsApp API with an official MCP server.
Claude Desktop, Claude Code, and any MCP-aware agent can call WhatsApp directly — no plumbing.
3 MCP tools, zero boilerplate
senwa_send_text, senwa_send_media, senwa_get_status. Drop into Claude Desktop or Claude Code config, your agent can now act on WhatsApp.

DX that respects your time.
Interactive docs, real-time webhook delivery logs, audit trails, multi-account dashboards. No support tickets to get started.
Anti-ban by default
Send-rate enforced atomically in Postgres. Send too fast on the same session, you get a 429 with Retry-After — never a banned number.
Clean error codes
Every failure returns a stable code (SEND_RATE_LIMITED, SESSION_DISCONNECTED, AUTH_INVALID). Your error handlers stay deterministic.
Migrate your old keys
Already on UltraMsg, Green API, or WaSender? Your customers' snw_ keys keep working — we preserve hashes across migrations.
