How can I send product details to Stripe as metadata?

When a customer places an order via the Stripe extension, you may want to send additional details to Stripe as metadata:

To do this, you can leverage one (or both) of the following filters:

• wc_stripe_intent_metadata if you’re using the new checkout experience
• wc_stripe_payment_metadata if you’re using the legacy experience

Here’s an example snippet:

add_filter( 'wc_stripe_intent_metadata', 'add_my_custom_stripe_metadata', 10, 2 );
add_filter( 'wc_stripe_payment_metadata', 'add_my_custom_stripe_metadata', 10, 2 );

function add_my_custom_stripe_metadata( $metadata, $order ) {

	// Add name, quantity, and price for each line item.
	$count = 1;
	foreach ( $order->get_items() as $item_id => $line_item ) {
		$product = $line_item->get_product();
		$product_name = $product->get_title();
		$item_quantity = $line_item->get_quantity();
		$item_total = $line_item->get_total();
		$metadata[ 'Line Item ' . $count ] = 'Product name: ' . $product_name . ' | Quantity: ' . $item_quantity . ' | Item total: ' . number_format( $item_total, 2 );
		$count += 1;
	}

	// Add whatever custom key/value pair you want. :)
	$metadata['my_custom_key'] = 'An example custom value.';

	return $metadata;
}

Here’s how the metadata from that snippets appears in the Stripe dashboard:
