WooCommerce hooks - Product update deliver variation objects instead of IDs - wordpress

Question

When receiving a product updated hook from WooCommerce, the payload contains a 'variations' array, which, however, only contains the IDs of the variations that belong to the updated product.
How can I send the actual variation objects along with the product updated payload, instead of only the IDs of the variation (this way, I wouldn't need to send another request to the variations resource of the REST API to fetch them).
Thanks!

Answer 1

You need to hook woocommerce_webhook_payload to build the payload. The details of the product variation are stored in variations_objs.
// Hook to the webhook build process and add your variations objects.
add_filter( 'woocommerce_webhook_payload', 'dolly_woocommerce_webhook_payload', 10, 4 );
function dolly_woocommerce_webhook_payload( $payload, $resource, $resource_id, $id ) {
// Remove the filter to eliminate the recursion calls.
remove_filter( 'woocommerce_webhook_payload', 'dolly_woocommerce_webhook_payload', 10 );
// Create a WC_Webhook class with the webhook id.
$wc_webhook = new WC_Webhook( $id );
// Bail early if the resource is not product.
if ( 'product' !== $resource ) {
return $payload;
}
// Bail early if the product type is not variable.
$product = new WC_Product( $resource_id );
if ( 'variable' === $product->get_type() ) {
return $payload;
}
// Build the payload of each product variation.
$variations = $payload['variations'];
foreach( $variations as $variation ) {
$variations_objs[] = $wc_webhook->build_payload( $variation );
}
// Add the varitions to the payload.
$payload['variations_objs'] = $variations_objs;
// Add the filter again and return the payload.
add_filter( 'woocommerce_webhook_payload', 'dolly_woocommerce_webhook_payload', 10, 4 );
return $payload;
}
Here is the data sent by the webhooks.
