# Google Chat

![Google Chat](https://raw.githubusercontent.com/ClawLink-HQ/clawlink/main/public/images/brand-logos/google-chat.svg?v=2)

Access Google Chat via the Google Chat API with OAuth authentication. Manage spaces, members, messages, attachments, and threaded conversations.

This skill uses [ClawLink](https://claw-link.dev/?utm_source=clawhub&utm_medium=referral&utm_content=google-chat-messaging) for hosted connection flows and credentials so you do not need to configure Google Chat API access yourself.

### Setup in 3 Steps

| Step 1: Install | Step 2: Pair Account | Step 3: Connect Google Chat |

```

## Install

Install the verified ClawLink plugin from ClawHub. After the user confirms, complete the full setup so ClawLink tools are visible in the next OpenClaw chat.

```bash
openclaw plugins install clawhub:clawlink-plugin
openclaw config set tools.alsoAllow '["clawlink-plugin"]' --strict-json
openclaw gateway restart
```

Then tell the user: "OpenClaw has been restarted. Send `/new` as a standalone message to start a fresh chat, then ask for Google Chat again."

## Quick Start

```bash
# List spaces the user is member of
clawlink_call_tool --tool "google_chat_list_spaces" --params '{}'

# List members in a space
clawlink_call_tool --tool "google_chat_list_members" --params '{"parent": "spaces/space-id"}'

# Send a message to a space
clawlink_call_tool --tool "google_chat_create_message" --params '{"parent": "spaces/space-id", "text": "Hello from OpenClaw!"}'
```

## Authentication

All Google Chat tool calls are authenticated automatically by ClawLink using the user's connected Google account.

**No API key is required in chat.** ClawLink stores the OAuth token securely and injects it into every Google Chat API request on the user's behalf.

### Getting Connected

1. Install the ClawLink plugin (see Install above).
2. Pair the plugin with `clawlink_begin_pairing` if it is not configured yet.
3. Open https://claw-link.dev/dashboard?add=google-chat and connect Google Chat.
4. Call `clawlink_list_integrations` to verify the connection is active.

## Connection Management

### List Connections

```bash
clawlink_list_integrations
```

**Response:** Returns all connected integrations. Look for `google-chat` in the list.

### Verify Connection

```bash
clawlink_list_tools --integration google-chat
```

**Response:** Returns the live tool catalog for Google Chat.

### Reconnect

If Google Chat tools are missing or the connection shows an error:

1. Direct the user to https://claw-link.dev/dashboard?add=google-chat
2. After they confirm, call `clawlink_list_integrations` to verify
3. Then call `clawlink_list_tools --integration google-chat`

## Security & Permissions

- Access is scoped to Google Chat spaces and messages accessible to the connected Google account.
- **All write operations require explicit user confirmation.** Before executing any message send, space create, or member change, confirm the intended effect with the user.
- Destructive actions (deleting spaces, removing members) are marked as high-impact and must be confirmed.
- Message size is limited to 32,000 bytes. Card-based messages require bot authentication.

  }'
```

## Discovery Workflow

1. Call `clawlink_list_integrations` to confirm Google Chat is connected.
2. Call `clawlink_list_tools --integration google-chat` to see the live catalog.
3. Treat the returned list as the source of truth. Do not guess or assume what tools exist.
4. If the user describes a capability but the exact tool is unclear, call `clawlink_search_tools` with a short query and integration `google-chat`.
5. If no Google Chat tools appear, direct the user to https://claw-link.dev/dashboard?add=google-chat.

## Execution Workflow

```
┌─────────────────────────────────────────────────────────────┐
│  READ OPERATIONS (Safe)                                     │
│  list → get → search → describe → call                      │
│                                                             │
│  Example: List spaces → Get space → Show members            │
└─────────────────────────────────────────────────────────────┘
                              │
                              ▼
┌─────────────────────────────────────────────────────────────┐
│  WRITE OPERATIONS (Require Confirmation)                    │
│  list → get → describe → preview → confirm → call           │
│                                                             │
│  Example: Preview message → User confirms → Execute send    │
└─────────────────────────────────────────────────────────────┘
```

1. For unfamiliar tools, ambiguous requests, or any write action, call `clawlink_describe_tool` first.
2. Use the returned guidance, schema, `whenToUse`, `askBefore`, `safeDefaults`, `examples`, and `followups` to shape the call.
3. Prefer read, list, search, and get operations before writes when that reduces ambiguity.
4. For writes or anything marked as requiring confirmation, call `clawlink_preview_tool` first.
5. Execute with `clawlink_call_tool`. Pass confirmation only after the preview matches the user's intent.
6. If the tool call fails, report the real error. Do not invent results or restate the failure as a missing capability unless the live catalog supports that conclusion.

## Notes

- Space names use format `spaces/space-id` in API calls.
- Message threading uses `thread_key` to reply to existing threads.
- Custom emojis are only available for Google Workspace accounts and require admin enablement.
- With user authentication, only plain text messages are supported. Card-based messages require bot authentication.
- Message size limit is 32,000 bytes.

## Error Handling

| Status / Error | Meaning |
|----------------|---------|
| Tool not found | The tool name does not exist in the current catalog. Verify with `clawlink_list_tools --integration google-chat`. |
| Missing connection | Google Chat is not connected. Direct the user to https://claw-link.dev/dashboard?add=google-chat. |
| `404 Not Found` | Space, message, or member does not exist. Verify the IDs. |
| `403 Forbidden` | Insufficient permissions or the space requires bot authentication. |
| Write rejected | User did not confirm a write action. Always confirm before executing writes. |

### Troubleshooting: Tools Not Visible

1. Check that the ClawLink plugin is installed:
   ```bash
   openclaw plugins list
   ```
2. If the plugin is installed but tools are missing, tell the user to send `/new` as a standalone message to reload the catalog.
3. If a fresh chat does not help, run:
   ```bash
   openclaw config set tools.alsoAllow '["clawlink-plugin"]' --strict-json
   openclaw gateway restart
   ```
4. After restart, tell the user to send `/new` again and retry.

### Troubleshooting: Invalid Tool Call

1. Ensure the integration slug is exactly `google-chat`.
2. Use `clawlink_describe_tool` to verify parameter names and types before calling.
3. For write operations, always call `clawlink_preview_tool` first.
