Hi @miqser,
Glad you reached out. At the moment GiveWP doesn’t have an integration for Redsys, but it is a feature request we are tracking here: https://feedback.givewp.com/feature-requests/p/redsys-payment-gateway. You can use this post to add comments of your own, and follow our progress. I’ve also linked your ticket here so we can reach back out to update you once we have a resolution for this.
I’ll go ahead and mark this as resolved for now, but if you have any questions you can create a new ticket right here and we’ll be happy to give things a look. Have a great day!
