Send key=wc_order by POST instead by GET

Hello,

I’m using woocommerce with Redsys TPV and I’ve got an error with url Notificatión HTTP because it is using parameters in the url and Redsys system doesn’t accept them; You can send parameters only by POST.

When I do a transaction, it comes back to https://sierraysol.com/checkout/order-received/5302/?key=wc_order_54d088b9528e5 (per example that test order) and Redsys doesn’t accept parameters with GET, Redsys only accepts them by POST.

Could you help me to change this and send the Notificaciton HTTP request with POST parameters instead?

Thank you so much in advance
