+# Paarrot API Quick Start
+
+A local HTTP API server for controlling Paarrot from external devices like Stream Deck, scripts, and automation tools.
+
+## 🚀 Getting Started
+
+The API server starts automatically when you run Paarrot. It listens on `http://127.0.0.1:33384`.
+
+### Test the API
+
+**Option 1: Using Postman**
+
+Import the Postman collection for easy testing:
+1. Open Postman
+2. Click **Import** → **File**
+3. Select `paarrot-api.postman_collection.json`
+4. All endpoints will be ready to use!
+
+The collection is automatically updated on git push.
+
+**Option 2: Using the test script**
+```bash
+node test-api.js
+```
+
+**Option 3: Using curl**
+```bash
+./test-api.sh
+```
+
+**Option 4: Manual curl commands**
+```bash
+# Health check
+curl http://127.0.0.1:33384/health
+
+# Toggle mute
+curl -X POST http://127.0.0.1:33384/mute/toggle
+
+# Send message
+curl -X POST http://127.0.0.1:33384/message/current \
+  -H "Content-Type: application/json" \
+  -d '{"message": "Hello from API!"}'
+```
+
+## 📝 Quick Reference
+
+### Common Endpoints
+
+| Endpoint | Method | Description |
+|----------|--------|-------------|
+| `/health` | GET | Check if API is running |
+| `/status` | GET | Get app status (mute, deafen, etc.) |
+| `/mute/toggle` | POST | Toggle microphone mute |
+| `/deafen/toggle` | POST | Toggle deafen |
+| `/channels` | GET | Get list of rooms |
+| `/channel` | POST | Switch to a room |
+| `/message/current` | POST | Send message to current room |
+
+## 🎮 Stream Deck Integration
+
+1. Install the "API Ninja" or "HTTP Request" plugin
+2. Create buttons with these settings:
+
+**Mute Toggle Button:**
+- URL: `http://127.0.0.1:33384/mute/toggle`
+- Method: POST
+
+**Quick Message Button:**
+- URL: `http://127.0.0.1:33384/message/current`
+- Method: POST
+- Body: `{"message": "BRB!"}`
+
+## 🔧 Integration with Paarrot
+
+To enable full functionality, you need to implement the action handlers in the Cinny frontend:
+
+1. Import the API handler in your app initialization:
+```typescript
+import { initPaarrotAPI } from './app/paarrot-api';
+
+// After Matrix client is initialized
+initPaarrotAPI(matrixClient);
+```
+
+2. Implement the TODO items in `cinny/src/app/paarrot-api.ts`:
+   - Mute/unmute logic (WebRTC audio)
+   - Deafen logic (WebRTC audio output)
+   - Navigation to rooms (router integration)
+   - Get current room from URL/state
+
+## 📖 Full Documentation
+
+See [API.md](API.md) for complete API documentation including:
+- All available endpoints
+- Request/response formats
+- Error handling
+- Code examples in multiple languages
+- Detailed integration guide
+
+## 🛠️ Configuration
+
+Edit `electron/api-server.js` to customize:
+- Port number (default: 33384)
+- Timeout duration (default: 10s)
+- CORS settings
+
+## 🐛 Troubleshooting
+
+**API not responding:**
+1. Check if Paarrot is running
+2. Look for "Paarrot API server listening" in console logs
+3. Verify port 33384 is not in use: `lsof -i :33384`
+
+**Actions not working:**
+1. Check browser console for errors
+2. Ensure `initPaarrotAPI()` is called in your app
+3. Implement the TODO items in `paarrot-api.ts`
+
+**Port in use:**
+Edit `electron/api-server.js` and change the port number in the constructor.
+

+- `test-api.js` - Node.js test script
+- `test-api.sh` - Bash test script
+- `API.md` - Full documentation
+
+## 🔐 Security
+
+- API only listens on localhost (127.0.0.1)
+- Not accessible from network
+- No authentication required (local only)
+- CORS enabled for all origins (safe since localhost only)
+
+## 💡 Examples
+
+**Python Script:**
+```python
+import requests
+
+def toggle_mute():
+    r = requests.post('http://127.0.0.1:33384/mute/toggle')
+    print(r.json())
+
+toggle_mute()
+```
+
+**JavaScript:**
+```javascript
+async function sendQuickMessage(msg) {
+  const res = await fetch('http://127.0.0.1:33384/message/current', {
+    method: 'POST',
+    headers: { 'Content-Type': 'application/json' },
+    body: JSON.stringify({ message: msg })
+  });
+  return res.json();
+}
+```
+
+## 🎯 Next Steps
+
+1. Run Paarrot: `npm run dev`
+2. Test the API: `node test-api.js`
+3. Integrate the handler: Import and call `initPaarrotAPI()`
+4. Implement the TODO items in `paarrot-api.ts`
+5. Create Stream Deck buttons or automation scripts!

+
+## Client-Side Implementation
+
+To enable the API functionality in the Paarrot app, you need to implement the action handlers in your Matrix client code. The API server sends actions via IPC to the renderer process, which should handle them and respond.
+
+### Example Handler (TypeScript/React)
+
+Add this to your app initialization:
+
+```typescript
+// Listen for API actions from the Electron API server
+if (window.electron?.api?.onAction) {
+  window.electron.api.onAction(async (action:  {
+    action: string;
+    params: any;
+    responseChannel: string;
+  }) => {
+    try {
+      let result;
+      
+      switch (action.action) {
+        case 'toggle-mute':
+          // Toggle microphone mute
+          result = await toggleMicrophone();
+          break;
+          
+        case 'set-mute':
+          // Set microphone mute state
+          result = await setMicrophone(action.params.muted);
+          break;
+          
+        case 'toggle-deafen':
+          // Toggle deafen (mute speakers)
+          result = await toggleDeafen();
+          break;
+          
+        case 'set-deafen':
+          // Set deafen state
+          result = await setDeafen(action.params.deafened);
+          break;
+          
+        case 'change-channel':
+          // Navigate to a different room
+          result = await changeRoom(action.params.roomId);
+          break;
+          
+        case 'get-channels':
+          // Get list of rooms
+          result = await getRoomList();
+          break;
+          
+        case 'send-message':
+          // Send message to specific room
+          result = await sendMessage(action.params.roomId, action.params.message);
+          break;
+          
+        case 'send-message-current':
+          // Send message to current room
+          result = await sendMessageToCurrent(action.params.message);
+          break;
+          
+        case 'get-current-room':
+          // Get current room info
+          result = await getCurrentRoomInfo();
+          break;
+          
+        case 'get-status':
+          // Get current app status
+          result = await getAppStatus();
+          break;
+          
+        default:
+          throw new Error(`Unknown action: ${action.action}`);
+      }
+      
+      // Send success response back
+      window.electron.api.sendResponse(action.responseChannel, {
+        success: true,
+        data: result
+      });
+    } catch (error) {
+      // Send error response back
+      window.electron.api.sendResponse(action.responseChannel, {
+        success: false,
+        error: error.message
+      });
+    }
+  });
+}
+```
+
+---
+
+## Configuration
+
+The API server can be configured by modifying `electron/api-server.js`:
+
+- **Default Port**: 33384 (can be changed in the constructor)
+- **Bind Address**: 127.0.0.1 (localhost only for security)
+- **Timeout**: 10 seconds for actions
+
+---
+
+## Security Notes
+
+1. The API server only listens on localhost (127.0.0.1) and is not accessible from the network
+2. No authentication is implemented - anyone with local access can control the app
+3. Consider adding API key authentication if needed for your use case
+4. CORS is enabled for all origins since it's localhost only
+
+---
+
+## Troubleshooting
+
+**API server not starting**:
+- Check if port 33384 is already in use
+- Check console logs for errors
+- Verify Express is installed: `npm install express cors body-parser`
+
+**Actions not working**:
+- Ensure the client-side handler is implemented
+- Check browser console for errors
+- Verify the action names match between API server and client
+
+**Timeout errors**:
+- Actions must respond within 10 seconds
+- Check if the Matrix client is initialized
+- Verify the action handler is registered
+
+---
+
+## Future Enhancements
+
+Potential features to add:
+- WebSocket support for real-time events
+- Authentication with API keys
+- Voice channel controls (join/leave)
+- User status updates
+- Notification controls
+- Screen sharing controls

+
+## Plugin API
+
+Plugins have access to:
+- **Matrix Client**: Full matrix-js-sdk client instance
+- **React**: For building UI components
+- **Commands**: Register custom slash commands
+- **UI Buttons**: Inject buttons into 11 locations across the app (nav lists, toolbars, headers, sidebar)
+- **UI Renderers**: Custom message and content renderers
+- **Settings**: Add custom settings sections per plugin
+- **Themes**: Register custom themes that appear in the theme selector
+- **Matrix Events**: Hook into raw Matrix events
+- **Timers**: Background intervals and timeouts, auto-cleaned on unload
+- **Notifications**: System notifications
+
+See the [Plugin API Reference](docs/PLUGIN_API.md) and [Button Registration API](docs/PLUGIN_BUTTON_API.md) for complete documentation.
+
+## Example Plugins
+
+Check out the `example-plugin/` directory for a simple example, or the `plugins/example-showcase-plugin/` for a full demonstration of all 11 UI button locations.
+
+## Troubleshooting
+
+### Plugin Won't Load
+
+1. Check the browser console for errors (F12 → Console)
+2. Look for `[PluginLoader]` messages
+3. Verify `index.js` exists in the plugin directory
+4. Ensure `plugin-metadata.json` is valid JSON
+
+### Plugin Crashes
+
+1. Disable the plugin in Settings → Plugins
+2. Check console for error stack traces
+3. Report the issue to the plugin author
+4. Try reinstalling the plugin
+
+### Performance Issues
+
+If Paarrot becomes slow:
+1. Disable plugins one by one to identify the culprit
+2. Check for memory leaks in the console
+3. Contact the plugin author with details

+# Plugin Button Registration API
+
+An easy way to register plugin buttons in various UI locations with positioning and grouping support.
+
+## Example Plugins
+
+- **[example-button-plugin/](example-button-plugin/)** - Simple examples showing basic usage patterns
+- **[example-showcase-plugin/](example-showcase-plugin/)** - Complete demonstration of ALL 11 locations ⭐
+
+## UI Locations
+
+Buttons render in two visual styles depending on location — **nav list rows** (icon + label, full width) or **icon buttons** (compact, toolbar/header style).
+
+### Nav List Rows
+
+These render as full-width list entries matching the style of built-in items like "Create Room" and "Message Search":
+
+| Location | Where it appears |
+|---|---|
+| `channel-list` | Space channel list, below Lobby and Message Search |
+| `home-section` | Home panel, inside the Rooms category above the room list |
+| `direct-messages` | Direct Messages panel, below "Create Chat" and above the CHATS dropdown |
+
+### Icon Buttons
+
+These render as compact icon buttons inline with other toolbar/header controls:
+
+| Location | Where it appears |
+|---|---|
+| `text-composer-toolbar` | Message composer toolbar (alongside emoji, sticker buttons) |
+| `composer-actions` | Left side of the composer, beside the `+` attach button |
+| `room-header` | Top room header bar, before the ⋮ menu button |
+| `room-menu` | Room ⋮ dropdown menu |
+| `message-actions` | Message hover action bar |
+| `user-menu` | Right-click popup on the user avatar |
+| `search-notification-section` | Notifications page header (right side) |
+| `sidebar-actions` | Left sidebar — appears in **two** places: above the Explore Servers icon, and above the Search icon in the sticky bottom section |
+
+> 💡 **Tip:** Install the [example-showcase-plugin](example-showcase-plugin/) to see exactly where each location appears in the UI!
+
+## Basic Usage
+
+### Simple Button
+
+```javascript
+module.exports = {
+  name: 'my-plugin',
+  version: '1.0.0',
+  
+  onLoad: (context) => {
+    context.ui.registerButton({
+      id: 'my-button',
+      location: 'text-composer-toolbar',
+      label: 'My Action',
+      icon: '🎨',
+      onClick: () => {
+        context.log('Button clicked!');
+      }
+    });
+  },
+  
+  onUnload: () => {
+    // Buttons are automatically cleaned up on plugin unload
+  }
+};
+```
+
+## Positioning
+
+### Before/After Positioning
+
+Place your button before or after existing buttons:
+
+```javascript
+context.ui.registerButton({
+  id: 'my-button',
+  location: 'text-composer-toolbar',
+  label: 'My Action',
+  icon: '✨',
+  position: {
+    before: 'emoji-picker-button', // Place before emoji picker
+    // OR
+    after: 'sticker-button' // Place after sticker button
+  }
+});
+```
+
+### Grouping Buttons
+
+Group related buttons together:
+
+```javascript
+context.ui.registerButton({
+  id: 'action-1',
+  location: 'text-composer-toolbar',
+  label: 'Action 1',
+  icon: '1️⃣',
+  position: {
+    group: 'my-plugin-tools',
+    order: 1 // Lower numbers appear first
+  }
+});
+
+context.ui.registerButton({
+  id: 'action-2',
+  location: 'text-composer-toolbar',
+  label: 'Action 2',
+  icon: '2️⃣',
+  position: {
+    group: 'my-plugin-tools',
+    order: 2
+  }
+});
+```
+
+### Combined Positioning and Grouping
+
+Place a group before/after other elements:
+
+```javascript
+context.ui.registerButton({
+  id: 'tool-1',
+  location: 'text-composer-toolbar',
+  label: 'Tool 1',
+  icon: '🔧',
+  position: {
+    group: 'my-tools',
+    after: 'emoji-picker-button',
+    order: 1
+  }
+});
+
+context.ui.registerButton({
+  id: 'tool-2',
+  location: 'text-composer-toolbar',
+  label: 'Tool 2',
+  icon: '🔨',
+  position: {
+    group: 'my-tools',
+    order: 2
+  }
+});
+```
+
+## Complete Example
+
+```javascript
+module.exports = {
+  name: 'custom-tools',
+  version: '1.0.0',
+  
+  onLoad: (context) => {
+    // Nav list row — appears below "Create Chat" in the DMs panel
+    context.ui.registerButton({
+      id: 'dm-favorites',
+      location: 'direct-messages',
+      label: 'Favourites',
+      icon: '⭐',
+      onClick: () => context.log('Favourites clicked!')
+    });
+
+    // Nav list row — appears in the space channel list
+    context.ui.registerButton({
+      id: 'quick-access',
+      location: 'channel-list',
+      label: 'Quick Access',
+      icon: '⚡',
+      onClick: () => context.log('Quick access clicked!')
+    });
+
+    // Icon button — appears in the message composer toolbar
+    context.ui.registerButton({
+      id: 'format-bold',
+      location: 'text-composer-toolbar',
+      label: 'Bold',
+      icon: '𝐁',
+      position: {
+        group: 'custom-formatting',
+        order: 1
+      },
+      onClick: () => context.log('Bold clicked!')
+    });
+
+    // Icon button — appears in the room header
+    context.ui.registerButton({
+      id: 'special-search',
+      location: 'room-header',
+      label: 'Special Search',
+      icon: '🔍',
+      position: { after: 'search-button' },
+      onClick: () => context.log('Special search clicked!')
+    });
+
+    // Sidebar icon — appears above Explore and above Search
+    context.ui.registerButton({
+      id: 'plugin-panel',
+      location: 'sidebar-actions',
+      label: 'Plugin Panel',
+      icon: '🧩',
+      onClick: () => context.log('Plugin panel clicked!')
+    });
+  },
+  
+  onUnload: () => {
+    // All registered buttons are automatically cleaned up
+  }
+};
+```
+
