Signal Messaging
Send, receive and react to Signal messages — and trigger workflows on inbound events.
Bring end-to-end encrypted Signal messaging into n8n. Send and receive messages, react with emoji, manage groups and members, and handle attachments — driven through a self-hosted signal-cli-rest-api service that links your Signal number as a device.
Built for secure notifications, approvals and human-in-the-loop steps where privacy matters. The trigger node polls for inbound activity — new messages, typing indicators, read receipts and sync events — so workflows can respond to conversations as they happen.
Signal trigger on an inbound message → run a human approval step → react with ✅ and reply when the work is done.
