Is it possible to access custom fields for orders, products, customers via WooCommerce REST API? If not natively, then what plugins or workarounds or hacks are out there that work? Thanks!
Answering my own question:
It is possible using the following: (using v3 legacy API)
To send custom fields back to the server: (For Orders)
{
"order_meta": {
"key": "value"
}
}
To retrieve custom fields from server use this filter with your end point:
http://www.example.com/wc-api/v3/orders?filter[meta]=true
This works for Products as well.
