# Create Order

Creates an order. Merchants and partners can add Level 2 and 3 data to payments to reduce risk and payment processing costs. For more information about processing payments, see checkout or multiparty checkout. Note: For error handling and troubleshooting, see Orders v2 errors.

```php
function createOrder(array $options): ApiResponse
```

# Patch Order

Updates an order with a `CREATED` or `APPROVED` status. You cannot update an order with the `COMPLETED` status.<br/><br/>To make an update, you must provide a `reference_id`. If you omit this value with an order that contains only one purchase unit, PayPal sets the value to `default` which enables you to use the path: <code>\"/purchase_units/@reference_id=='default'/{attribute-or-object}\"</code>. Merchants and partners can add Level 2 and 3 data to payments to reduce risk and payment processing costs.
