# Dropbox

Access the Dropbox API with managed OAuth authentication. Manage files and folders, search content, retrieve metadata, and work with file revisions.

## Quick Start

```bash
# List files in root folder
python <<'EOF'
import urllib.request, os, json
data = json.dumps({"path": ""}).encode()
req = urllib.request.Request('https://gateway.maton.ai/dropbox/2/files/list_folder', data=data, method='POST')
req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}')
req.add_header('Content-Type', 'application/json')
print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2))
EOF
```

## Base URL

```
https://gateway.maton.ai/dropbox/2/{endpoint}
```

The gateway proxies requests to `api.dropboxapi.com` (for most endpoints) or `content.dropboxapi.com` (for upload/download endpoints) and automatically injects your OAuth token. The routing is handled automatically based on the endpoint path.

**Important:** Dropbox API v2 uses POST for all endpoints with JSON request bodies.

**Content Endpoints:** Upload and download endpoints use a different request format where file content is sent as the raw request body and parameters are passed in the `Dropbox-API-Arg` header as JSON. The gateway handles routing to the correct Dropbox host automatically.

## Authentication

All requests require the Maton API key in the Authorization header:

```
Authorization: Bearer $MATON_API_KEY
```

**Environment Variable:** Set your API key as `MATON_API_KEY`:

```bash
export MATON_API_KEY="YOUR_API_KEY"
```

### Getting Your API Key

1. Sign in or create an account at [maton.ai](https://maton.ai)
2. Go to [maton.ai/settings](https://maton.ai/settings)
3. Copy your API key

## Connection Management

Manage your Dropbox OAuth connections at `https://ctrl.maton.ai`.

### List Connections

```bash
python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://ctrl.maton.ai/connections?app=dropbox&status=ACTIVE')
req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}')
print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2))
EOF
```

### Create Connection

```bash
python <<'EOF'
import urllib.request, os, json
data = json.dumps({'app': 'dropbox'}).encode()
req = urllib.request.Request('https://ctrl.maton.ai/connections', data=data, method='POST')
req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}')
req.add_header('Content-Type', 'application/json')
print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2))
EOF
```

### Get Connection

```bash
python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://ctrl.maton.ai/connections/{connection_id}')
req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}')
print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2))
EOF
```

**Response:**
```json
{
  "connection": {
    "connection_id": "{connection_id}",
    "status": "ACTIVE",
    "creation_time": "2026-02-09T23:34:49.818074Z",
    "last_updated_time": "2026-02-09T23:37:09.697559Z",
    "url": "https://connect.maton.ai/?session_token=...",
    "app": "dropbox",
    "metadata": {}
  }
}
```

Open the returned `url` in a browser to complete OAuth authorization.

### Delete Connection

```bash
python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://ctrl.maton.ai/connections/{connection_id}', method='DELETE')
req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}')
print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2))
EOF
```

### Specifying Connection

If you have multiple Dropbox connections, specify which one to use with the `Maton-Connection` header:

```bash
python <<'EOF'
import urllib.request, os, json
data = json.dumps({"path": ""}).encode()
req = urllib.request.Request('https://gateway.maton.ai/dropbox/2/files/list_folder', data=data, method='POST')
req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}')
req.add_header('Content-Type', 'application/json')
req.add_header('Maton-Connection', '{connection_id}')
print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2))
EOF
```

If omitted, the gateway uses the default (oldest) active connection.

}
```

The link is valid for 4 hours.

### File Upload

**Note:** Upload endpoints use a different request format. File content is sent as the raw request body, and parameters are passed in the `Dropbox-API-Arg` header as JSON. The gateway automatically routes these to `content.dropboxapi.com`.

#### Upload File (up to 150 MB)

```bash
POST /dropbox/2/files/upload
Content-Type: application/octet-stream
Dropbox-API-Arg: {"path": "/test.txt", "mode": "add", "autorename": true, "mute": false}

<file contents>
```

**Parameters (in Dropbox-API-Arg header):**
- `path` (required) - Path in Dropbox where the file will be saved
- `mode` - Write mode: `add` (default), `overwrite`, or `update` with rev
- `autorename` - If true, rename file if there's a conflict (default: false)
- `mute` - If true, don't notify desktop app (default: false)
- `strict_conflict` - If true, be more strict about conflicts (default: false)

**Response:**
```json
{
  "name": "test.txt",
  "path_lower": "/test.txt",
  "path_display": "/test.txt",
  "id": "id:Awe3Av8A8YYAAAAAAAAABw",
  "client_modified": "2026-04-14T10:00:00Z",
  "server_modified": "2026-04-14T10:00:01Z",
  "rev": "016311c063b4f8700000002caa704e4",
  "size": 1024,
  "is_downloadable": true,
  "content_hash": "e3b0c44298fc1c149afbf4c8996fb92427ae41e4649b934ca495991b7852b855"
}
```

#### Upload Large Files (Upload Session)

For files larger than 150 MB, use upload sessions. Files can be up to 350 GB.

**Step 1: Start Session**

```bash
POST /dropbox/2/files/upload_session/start
Content-Type: application/octet-stream
Dropbox-API-Arg: {"close": false}

<first chunk of file content>
```

**Response:**
```json
{
  "session_id": "AAAAAAAAAAFxxxxxxxxxxxxxxx"
}
```

**Step 2: Append Data (repeat as needed)**

```bash
POST /dropbox/2/files/upload_session/append_v2
Content-Type: application/octet-stream
Dropbox-API-Arg: {"cursor": {"session_id": "AAAAAAAAAAFxxxxxxxxxxxxxxx", "offset": 10000000}, "close": false}

<next chunk of file content>
```

The `offset` must match the total bytes uploaded so far.

**Step 3: Finish Session**

```bash
POST /dropbox/2/files/upload_session/finish
Content-Type: application/octet-stream
Dropbox-API-Arg: {"cursor": {"session_id": "AAAAAAAAAAFxxxxxxxxxxxxxxx", "offset": 50000000}, "commit": {"path": "/large_file.zip", "mode": "add", "autorename": true}}

<final chunk of file content, can be empty>
```

**Response:** Same as regular upload endpoint.

#### Finish Multiple Upload Sessions (Batch)

Complete multiple upload sessions in one call:

```bash
POST /dropbox/2/files/upload_session/finish_batch
Content-Type: application/json

{
  "entries": [
    {

    {"from_path": "/old/file2.pdf", "to_path": "/new/file2.pdf"}
  ],
  "autorename": false
}
```

## Pagination

Dropbox uses cursor-based pagination. When `has_more` is true, use the `/continue` endpoint with the returned cursor.

```python
import os
import requests

headers = {
    'Authorization': f'Bearer {os.environ["MATON_API_KEY"]}',
    'Content-Type': 'application/json'
}

# Initial request
response = requests.post(
    'https://gateway.maton.ai/dropbox/2/files/list_folder',
    headers=headers,
    json={'path': '', 'limit': 100}
)
result = response.json()
all_entries = result['entries']

# Continue while has_more is True
while result.get('has_more'):
    response = requests.post(
        'https://gateway.maton.ai/dropbox/2/files/list_folder/continue',
        headers=headers,
        json={'cursor': result['cursor']}
    )
    result = response.json()
    all_entries.extend(result['entries'])

print(f"Total entries: {len(all_entries)}")
```

    offset = len(chunk)
    
    # Append remaining chunks
    while True:
        chunk = f.read(CHUNK_SIZE)
        if not chunk:
            break
        
        if offset + len(chunk) < file_size:
            # More chunks to come
            requests.post(

            break
```

## Notes

- All Dropbox API v2 endpoints use HTTP POST method
- Most endpoints use JSON request bodies (Content-Type: application/json)
- Upload/download endpoints use binary content (Content-Type: application/octet-stream) with parameters in `Dropbox-API-Arg` header
- The gateway automatically routes content endpoints to `content.dropboxapi.com`
- Use empty string `""` for the root folder path
- Paths are case-insensitive but case-preserving
- File IDs (e.g., `id:Awe3Av8A8YYAAAAAAAAABQ`) persist even when files are moved or renamed
- Tag text must match pattern `[\w]+` (alphanumeric and underscores only)
- Temporary download links expire after 4 hours
- Rate limits are generous and per-user
- Maximum file size for single upload: 150 MB (use upload sessions for larger files up to 350 GB)
- IMPORTANT: When piping curl output to `jq` or other commands, environment variables like `$MATON_API_KEY` may not expand correctly in some shell environments

## Error Handling

| Status | Meaning |
|--------|---------|
| 400 | Missing Dropbox connection or bad request |
| 401 | Invalid or missing Maton API key |
| 404 | Resource not found |
| 409 | Conflict (path doesn't exist, already exists, etc.) |
| 429 | Rate limited |
| 4xx/5xx | Passthrough error from Dropbox API |

Error responses include details:
```json
{
  "error_summary": "path/not_found/...",
  "error": {
    ".tag": "path",
    "path": {
      ".tag": "not_found"
    }
  }
}
```

### Troubleshooting: Invalid API Key

**When you receive an "Invalid API key" error, ALWAYS follow these steps before concluding there is an issue:**

1. Check that the `MATON_API_KEY` environment variable is set:

```bash
echo $MATON_API_KEY
```

2. Verify the API key is valid by listing connections:

```bash
python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://ctrl.maton.ai/connections')
req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}')
print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2))
EOF
```
