Integrate Redsys on Give WP

Hi there, apologies for the delayed response.

This is the best way to better understand how to integrate custom gateways with Give:

1) Review our code in the core Give plugin found in “wp-content/plugins/give/includes/gateways/”

2) Read through this article our colleague Chris Flannagan wrote on the subject: https://whoischris.com/building-payment-gateway-give-wp-donation-plugin-wordpress/

Thanks!
