Approval Channel

The approval channel is configured in openclaw.json:

json5

{
  skills: {
    entries: {
      "approval-gate": {
        enabled: true,
        env: {
          APPROVAL_CHANNEL: "whatsapp",
          APPROVAL_TARGET: "+15551234567",
          APPROVAL_TIMEOUT_MINUTES: "30",
        },
      },
    },
  },
}

Approval Message Format

When an action requires approval, the gate posts:

code

🔒 Approval Required

Action: Send email

Subject: Meeting follow-up
Body preview: Hi John, following up on...

Reply "approve" to execute or "deny" to cancel.
Expires in 30 minutes.
