OpenClaw Signal Integration Guide

February 21, 20263 min readReviewed February 21, 2026

OpenClaw integrates with Signal using signal-cli, not an embedded libsignal implementation[1]. That design keeps the transport path explicit and easier to debug when onboarding multiple accounts.

What You Need

Signal account linked and usable from signal-cli[2].
OpenClaw configured with the Signal channel block[1].
Pairing policy enabled for unknown DMs[3].

Baseline Configuration

{
  "channels": {
    "signal": {
      "dmPolicy": "pairing",
      "groupPolicy": "allowlist"
    }
  }
}

First-Pass Validation

openclaw channels status --probe
openclaw pairing list signal
openclaw logs --follow

Use this exact sequence after config changes. If probe is healthy but replies do not send, pairing state is usually the first root cause[3][4].

Approve Pending Users

openclaw pairing approve signal <CODE>
openclaw pairing reject signal <CODE>

Approvals add senders to allowlist storage so future messages can route without manual steps[3].

Multi-Account Pattern

If you run multiple Signal identities, keep account-level separation in channel config and use deterministic routing to avoid cross-thread confusion[1][5].

Troubleshooting Path

Confirm signal-cli can send/receive independently[2].
Run OpenClaw probe and inspect channel capability output[4].
Check pairing queue and DM policy mismatch[3].
Inspect logs for re-auth loops or account credential issues[6].
