WooCommerce REST API - Filter Orders By Date Modified

This worked for me. Tested with Woo 4.0.x / API v3

add_filter('woocommerce_rest_orders_prepare_object_query', function(array $args, \WP_REST_Request $request) {    $modified_after = $request->get_param('modified_after');    if (!$modified_after) {        return $args;    }    $args['date_query'][0]['column'] = 'post_modified';    $args['date_query'][0]['after']  = $modified_after;    return $args;}, 10, 2);

/wp-json/wc/v3/orders/?modified_after=2020-05-09T14:00:00

Hope it helps someone.

I've solved the problem with the following steps:

1. Create a folder.

2. Create a file with the same name and the following content:

   <?php/** * Plugin Name: ModifyOrder */function modify_orders_after_query($request) {    $request['date_query'][0]['column'] = 'post_modified';    return $request;}add_filter( "woocommerce_rest_orders_prepare_object_query", 'modify_orders_after_query' );

3. Drop it in the wp-content/plugins folder.

4. In the admin panel, you can see your folder name as a plugin,activate it and try!

This is working:

/wp-json/wc/v2/orders?after=2019-01-10T00:00:00Z&before=2019-01-10T23:59:59Z
