Synology Chat (plugin)

Status: supported via plugin as a direct-message channel using Synology Chat webhooks.

The plugin accepts inbound messages from Synology Chat outgoing webhooks and sends replies

through a Synology Chat incoming webhook.

Plugin required

Synology Chat is plugin-based and not part of the default core channel install.

Install from a local checkout:

openclaw plugins install ./path/to/local/synology-chat-plugin

Quick setup

1. Install and enable the Synology Chat plugin.
• openclaw onboard now shows Synology Chat in the same channel setup list as openclaw channels add.
• Non-interactive setup: openclaw channels add --channel synology-chat --token <token> --url <incoming-webhook-url>
2. In Synology Chat integrations:
• Create an incoming webhook and copy its URL.
• Create an outgoing webhook with your secret token.
3. Point the outgoing webhook URL to your OpenClaw gateway:
• https://gateway-host/webhook/synology by default.
• Or your custom channels.synology-chat.webhookPath.
4. Finish setup in OpenClaw.
• Guided: openclaw onboard
• Direct: openclaw channels add --channel synology-chat --token <token> --url <incoming-webhook-url>
5. Restart gateway and send a DM to the Synology Chat bot.

Minimal config:

{
  channels: {
    "synology-chat": {
      enabled: true,
      token: "synology-outgoing-token",
      incomingUrl: "https://nas.example.com/webapi/entry.cgi?api=SYNO.Chat.External&method=incoming&version=2&token=...",
      webhookPath: "/webhook/synology",
      dmPolicy: "allowlist",
      allowedUserIds: ["123456"],
      rateLimitPerMinute: 30,
      allowInsecureSsl: false,
    },
  },
}

Environment variables

For the default account, you can use env vars:

• SYNOLOGY_CHAT_TOKEN
• SYNOLOGY_CHAT_INCOMING_URL
• SYNOLOGY_NAS_HOST
• SYNOLOGY_ALLOWED_USER_IDS (comma-separated)
• SYNOLOGY_RATE_LIMIT
• OPENCLAW_BOT_NAME

Config values override env vars.

DM policy and access control

• dmPolicy: "allowlist" is the recommended default.
• allowedUserIds accepts a list (or comma-separated string) of Synology user IDs.
• In allowlist mode, an empty allowedUserIds list is treated as misconfiguration and the webhook route will not start (use dmPolicy: "open" for allow-all).
• dmPolicy: "open" allows any sender.
• dmPolicy: "disabled" blocks DMs.
• Reply recipient binding stays on stable numeric user_id by default. channels.synology-chat.dangerouslyAllowNameMatching: true is break-glass compatibility mode that re-enables mutable username/nickname lookup for reply delivery.
• Pairing approvals work with:
• openclaw pairing list synology-chat
• openclaw pairing approve synology-chat <CODE>

Outbound delivery

Use numeric Synology Chat user IDs as targets.

Examples:

openclaw message send --channel synology-chat --target 123456 --text "Hello from OpenClaw"
openclaw message send --channel synology-chat --target synology-chat:123456 --text "Hello again"

Media sends are supported by URL-based file delivery.

Multi-account

Multiple Synology Chat accounts are supported under channels.synology-chat.accounts.

Each account can override token, incoming URL, webhook path, DM policy, and limits.

Direct-message sessions are isolated per account and user, so the same numeric user_id

on two different Synology accounts does not share transcript state.

Give each enabled account a distinct webhookPath. OpenClaw now rejects duplicate exact paths

and refuses to start named accounts that only inherit a shared webhook path in multi-account setups.

If you intentionally need legacy inheritance for a named account, set

dangerouslyAllowInheritedWebhookPath: true on that account or at channels.synology-chat,

but duplicate exact paths are still rejected fail-closed. Prefer explicit per-account paths.

{
  channels: {
    "synology-chat": {
      enabled: true,
      accounts: {
        default: {
          token: "token-a",
          incomingUrl: "https://nas-a.example.com/...token=...",
        },
        alerts: {
          token: "token-b",
          incomingUrl: "https://nas-b.example.com/...token=...",
          webhookPath: "/webhook/synology-alerts",
          dmPolicy: "allowlist",
          allowedUserIds: ["987654"],
        },
      },
    },
  },
}

Security notes

• Keep token secret.
• Keep allowInsecureSsl: false unless you explicitly trust a self-signed local NAS cert.
• Inbound webhook requests are token-verified and rate-limited per sender.
• Prefer dmPolicy: "allowlist" for production.
• Keep dangerouslyAllowNameMatching off unless you explicitly need legacy username-based reply delivery.
• Keep dangerouslyAllowInheritedWebhookPath off unless you explicitly accept shared-path routing risk in a multi-account setup.
