# QuickBooks

Access the QuickBooks Online API with managed OAuth authentication. Manage customers, vendors, invoices, payments, and run financial reports.

## Quick Start

```bash
# Query customers
python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://gateway.maton.ai/quickbooks/v3/company/:realmId/query?query=SELECT%20*%20FROM%20Customer%20MAXRESULTS%20100')
req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}')
print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2))
EOF
```

## Base URL

```
https://gateway.maton.ai/quickbooks/{native-api-path}
```

Replace `{native-api-path}` with the actual QuickBooks API endpoint path. The gateway proxies requests to `quickbooks.api.intuit.com`. The `:realmId` placeholder is automatically replaced with your company's realm ID from connection config.

## 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 QuickBooks 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=quickbooks&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': 'quickbooks'}).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": "21fd90f9-5935-43cd-b6c8-bde9d915ca80",
    "status": "ACTIVE",
    "creation_time": "2025-12-08T07:20:53.488460Z",
    "last_updated_time": "2026-01-31T20:03:32.593153Z",
    "url": "https://connect.maton.ai/?session_token=...",
    "app": "quickbooks",
    "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 QuickBooks connections, specify which one to use with the `Maton-Connection` header:

```bash
python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://gateway.maton.ai/quickbooks/v3/company/:realmId/companyinfo/:realmId')
req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}')
req.add_header('Maton-Connection', '21fd90f9-5935-43cd-b6c8-bde9d915ca80')
print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2))
EOF
```

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

## Query Language

QuickBooks uses SQL-like queries:

```sql
SELECT * FROM Customer WHERE DisplayName LIKE 'John%' MAXRESULTS 100
```

Operators: `=`, `LIKE`, `<`, `>`, `<=`, `>=`, `IN`

## SyncToken

All updates require the current `SyncToken`:
1. GET the entity to get current `SyncToken`
2. Include `Id` and `SyncToken` in POST body
3. If SyncToken doesn't match, update fails

## Code Examples

### JavaScript

```javascript
const response = await fetch(
  'https://gateway.maton.ai/quickbooks/v3/company/:realmId/query?query=SELECT%20*%20FROM%20Customer',
  {
    headers: {
      'Authorization': `Bearer ${process.env.MATON_API_KEY}`
    }
  }
);
```

### Python

```python
import os
import requests

response = requests.get(
    'https://gateway.maton.ai/quickbooks/v3/company/:realmId/query',
    headers={'Authorization': f'Bearer {os.environ["MATON_API_KEY"]}'},
    params={'query': 'SELECT * FROM Customer MAXRESULTS 10'}
)
```

## Notes

- `:realmId` is automatically replaced by the router
- All queries must be URL-encoded
- Use `MAXRESULTS` to limit query results
- Dates are in `YYYY-MM-DD` format
- Soft delete entities by setting `Active: false`
- IMPORTANT: When using curl commands, use `curl -g` when URLs contain brackets (`fields[]`, `sort[]`, `records[]`) to disable glob parsing
- IMPORTANT: When piping curl output to `jq` or other commands, environment variables like `$MATON_API_KEY` may not expand correctly in some shell environments. You may get "Invalid API key" errors when piping.

## Error Handling

| Status | Meaning |
|--------|---------|
| 400 | Missing QuickBooks connection |
| 401 | Invalid or missing Maton API key |
| 429 | Rate limited (10 req/sec per account) |
| 4xx/5xx | Passthrough error from QuickBooks API |

### Troubleshooting: API Key Issues

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
```

### Troubleshooting: Invalid App Name

1. Ensure your URL path starts with `quickbooks`. For example:

- Correct: `https://gateway.maton.ai/quickbooks/v3/company/:realmId/query`
- Incorrect: `https://gateway.maton.ai/v3/company/:realmId/query`
