Introduction
# 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.
## API Reference
### Company Info
```bash GET /quickbooks/v3/company/:realmId/companyinfo/:realmId ```
### Customers
#### Query Customers
```bash GET /quickbooks/v3/company/:realmId/query?query=SELECT%20*%20FROM%20Customer%20MAXRESULTS%20100 ```
#### Get Customer
```bash GET /quickbooks/v3/company/:realmId/customer/{customerId} ```
#### Create Customer
```bash POST /quickbooks/v3/company/:realmId/customer Content-Type: application/json
{ "DisplayName": "John Doe", "PrimaryEmailAddr": {"Address": "[email protected]"}, "PrimaryPhone": {"FreeFormNumber": "555-1234"} } ```
#### Update Customer
Requires `Id` and `SyncToken` from previous GET:
```bash POST /quickbooks/v3/company/:realmId/customer Content-Type: application/json
{ "Id": "123", "SyncToken": "0", "DisplayName": "John Doe Updated" } ```
### Invoices
#### Query Invoices
```bash GET /quickbooks/v3/company/:realmId/query?query=SELECT%20*%20FROM%20Invoice%20MAXRESULTS%20100 ```
#### Create Invoice
```bash POST /quickbooks/v3/company/:realmId/invoice Content-Type: application/json
{ "CustomerRef": {"value": "123"}, "Line": [ { "Amount": 100.00, "DetailType": "SalesItemLineDetail", "SalesItemLineDetail": { "ItemRef": {"value": "1"}, "Qty": 1 } } ] } ```
#### Delete Invoice

{ "Id": "123", "SyncToken": "0" } ```
### Payments
#### Create Payment
```bash POST /quickbooks/v3/company/:realmId/payment Content-Type: application/json

### Reports
#### Profit and Loss
```bash GET /quickbooks/v3/company/:realmId/reports/ProfitAndLoss?start_date=2024-01-01&end_date=2024-12-31 ```
#### Balance Sheet
```bash GET /quickbooks/v3/company/:realmId/reports/BalanceSheet?date=2024-12-31 ```

{ "BatchItemRequest": [ {"bId": "1", "Query": "SELECT * FROM Customer MAXRESULTS 2"}, {"bId": "2", "Query": "SELECT * FROM Vendor MAXRESULTS 2"} ] } ```
## 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`
