## __experimental_woocommerce_blocks_checkout_order_processed


Fires before an order is processed by the Checkout Block/Store API.

```php
do_action( '__experimental_woocommerce_blocks_checkout_order_processed', \WC_Order $order )
```


**Note: This Hook is experimental and may change or be removed.**

### Description

<p>This hook informs extensions that $order has completed processing and is ready for payment.</p> <p>This is similar to existing core hook woocommerce_checkout_order_processed. We're using a new action:</p> <ul> <li>To keep the interface focused (only pass $order, not passing request data).</li> <li>This also explicitly indicates these orders are from checkout block/StoreAPI.</li> </ul>

### Parameters

| Argument | Type | Description |
| -------- | ---- | ----------- |
| $order | \WC_Order | Order object. |

### Example

```php
// The action callback function.
function my_function_callback( $order ) {
  // Do something with the $order object.
  $order->save();
}

add_action( '__experimental_woocommerce_blocks_checkout_order_processed', 'my_function_callback', 10 );
```
