Nextcloud Talk (plugin)

Status: supported via plugin (webhook bot). Direct messages, rooms, reactions, and markdown messages are supported.

Plugin required

Nextcloud Talk ships as a plugin and is not bundled with the core install.

Install via CLI (npm registry):

hanzo-bot plugins install @hanzo/bot-nextcloud-talk

Local checkout (when running from a git repo):

hanzo-bot plugins install ./extensions/nextcloud-talk

If you choose Nextcloud Talk during configure/onboarding and a git checkout is detected, HanzoBot will offer the local install path automatically.

Details: Plugins

Quick setup (beginner)

1. Install the Nextcloud Talk plugin.

2. On your Nextcloud server, create a bot:

   ./occ talk:bot:install "HanzoBot" "<shared-secret>" "<webhook-url>" --feature reaction
   

3. Enable the bot in the target room settings.

4. Configure HanzoBot:

   • Config: channels.nextcloud-talk.baseUrl + channels.nextcloud-talk.botSecret
   • Or env: NEXTCLOUD_TALK_BOT_SECRET (default account only)

5. Restart the gateway (or finish onboarding).

Minimal config:

{
  channels: {
    "nextcloud-talk": {
      enabled: true,
      baseUrl: "https://cloud.example.com",
      botSecret: "shared-secret",
      dmPolicy: "pairing",
    },
  },
}

Notes

• Bots cannot initiate DMs. The user must message the bot first.
• Webhook URL must be reachable by the Gateway; set webhookPublicUrl if behind a proxy.
• Media uploads are not supported by the bot API; media is sent as URLs.
• The webhook payload does not distinguish DMs vs rooms; set apiUser + apiPassword to enable room-type lookups (otherwise DMs are treated as rooms).

Access control (DMs)

• Default: channels.nextcloud-talk.dmPolicy = "pairing". Unknown senders get a pairing code.
• Approve via:
  • hanzo-bot pairing list nextcloud-talk
  • hanzo-bot pairing approve nextcloud-talk <CODE>
• Public DMs: channels.nextcloud-talk.dmPolicy="open" plus channels.nextcloud-talk.allowFrom=["*"].
• allowFrom matches Nextcloud user IDs only; display names are ignored.

Rooms (groups)

• Default: channels.nextcloud-talk.groupPolicy = "allowlist" (mention-gated).
• Allowlist rooms with channels.nextcloud-talk.rooms:

{
  channels: {
    "nextcloud-talk": {
      rooms: {
        "room-token": { requireMention: true },
      },
    },
  },
}

• To allow no rooms, keep the allowlist empty or set channels.nextcloud-talk.groupPolicy="disabled".
