# ChatGPT Conversation History - Implementation Complete

**Date:** 2026-02-23  
**Status:** ✅ Ready for Testing

## What Was Built

### 1. Backend Service
**File:** `src/gateway/services/ChatGPTConversationsService.ts`
- Fetches conversations from `https://chatgpt.com/backend-api/conversations`
- Supports pagination, sorting, filtering
- Uses OAuth access token from environment

### 2. WebSocket Handler
**File:** `src/gateway/websocket/chatgpt.ts`
- Handles `chatgpt:list-conversations` message
- Handles `chatgpt:get-conversation` message (single conversation)
- Integrated into main WebSocket router

### 3. UI View Component
**Files:**
- `ui/components/ChatGPT/ChatGPTConvHistoryView.tsx`
- `ui/components/ChatGPT/ChatGPTConvHistoryView.css`

**Features:**
- Lists ChatGPT conversations with pagination
- Shows conversation title, model, timestamps
- Checks OAuth status before fetching
- Error handling and loading states

### 4. Integration
- Added `chatgpt-conv-history` tab type to `ui/types/tabs.ts`
- Registered view in `ContentArea.tsx`
- Added "View ChatGPT History" button in Settings → Data tab

## How to Test

### 1. Start the App
```bash
npm start
```

### 2. Connect OpenAI OAuth
- Go to Settings → API Keys
- Connect your ChatGPT account via OAuth
- This provides the access token needed for API calls

### 3. Open ChatGPT History
Two ways to access:

**Option A: Via Settings**
1. Open Settings (⚙️ icon in sidebar)
2. Go to "Data" tab
3. Click "View ChatGPT History" button

**Option B: Via Command Palette** (if added later)
1. Press Cmd+K
2. Search for "ChatGPT History"

### 4. Fetch Conversations
1. Click "Fetch Conversations" button
2. Wait for API response
3. View your ChatGPT conversation list!

## API Endpoint Details

**Confirmed Working Endpoint:**
```
GET https://chatgpt.com/backend-api/conversations
  ?offset=0
  &limit=28
  &order=-updated
  &is_archived=false
  &is_starred=false
```

**Required Headers:**
```
Authorization: Bearer <oauth_access_token>
Accept: */*
User-Agent: Mozilla/5.0 ...
```

**Response Structure:**
```json
{
  "items": [
    {
      "id": "conv-abc123...",
      "title": "Conversation title",
      "create_time": 1708698600,
      "update_time": 1708706700,
      "model_slug": "gpt-5.3-codex",
      "is_archived": false
    }
  ],
  "total": 142,
  "limit": 28,
  "offset": 0,
  "has_next": true
}
```

## What Works

✅ OAuth authentication check  
✅ Fetch conversations list  
✅ Pagination (Previous/Next)  
✅ Display conversation metadata  
✅ Error handling  
✅ Loading states  

## What's Next (Future Enhancements)

### Phase 2: Import Feature
- [ ] Fetch individual conversation details (messages)
- [ ] Convert ChatGPT format → Paprwork format
- [ ] Import selected conversations into local storage
- [ ] Preserve tool calls, thinking, attachments

### Phase 3: Export Feature
- [ ] Export Paprwork chats to ChatGPT format
- [ ] Bulk operations (select multiple)
- [ ] Search/filter conversations

### Phase 4: Sync Feature (Advanced)
- [ ] Two-way sync between ChatGPT and Paprwork
- [ ] Conflict resolution
- [ ] Auto-sync on interval

## Testing Checklist

- [ ] OAuth connected successfully
- [ ] "View ChatGPT History" button opens new tab
- [ ] Conversations list loads without errors
- [ ] Pagination works (Previous/Next)
- [ ] Conversation details display correctly
- [ ] Error states show helpful messages
- [ ] Loading spinner appears during fetch

## Known Limitations

1. **No message content** - List endpoint doesn't include messages, only metadata
2. **Single conversation fetch** - Not tested yet (needs confirmation)
3. **No import yet** - Can view but not import into Paprwork
4. **Rate limits** - Unknown, be cautious with frequent requests
5. **OAuth token expiry** - Need to handle refresh token flow

## Files Created/Modified

### Created (8 files)
1. `src/gateway/services/ChatGPTConversationsService.ts`
2. `src/gateway/websocket/chatgpt.ts`
3. `ui/components/ChatGPT/ChatGPTConvHistoryView.tsx`
4. `ui/components/ChatGPT/ChatGPTConvHistoryView.css`
5. `scripts/test-chatgpt-conversations.mjs`
6. `docs/CHATGPT_CONVERSATIONS_API.md`

### Modified (5 files)
1. `ui/types/tabs.ts` - Added `chatgpt-conv-history` tab type
2. `ui/components/Layout/ContentArea.tsx` - Registered view
3. `ui/components/Settings/SettingsView.tsx` - Added button + import
4. `src/gateway/websocket/index.ts` - Registered handler
5. `scripts/test-chatgpt-conversations.mjs` - Updated with confirmed endpoint

## Troubleshooting

### "OpenAI OAuth not connected"
→ Connect ChatGPT in Settings → API Keys first

### "Failed to fetch conversations: 401"
→ OAuth token expired or invalid, reconnect

### "Failed to fetch conversations: 429"
→ Rate limited, wait and try again

### "Network error"
→ Check internet connection, ChatGPT servers may be down
