WooCommerce REST API - Filter Orders By Date Modified

Question

I'm using the WooCommerce REST API (http://woocommerce.github.io/woocommerce-rest-api-docs/#introduction) and can download Customers, Orders, etc successfully.

I'm now trying to get a filtered list of Orders where the Date Modified for the Order is after a certain date, but haven't been able to get this to work so far. The response to get GET request for an Order includes:

"date_modified": "2016-12-21T00:33:38",

I've tried the following:

wp-json/wc/v1/orders?filter[modified]=2017-02-14

but that just returns all orders. I would like to change the = to be a >= so it gets all Orders after the specified date, but haven't been able to find an example of how to structure the request URL for this?

Answer 1

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.
