How to integrate Wishlist Member Easy Digital Downloads Plus with the payment gateway?

Wishlist Member Easy Digital Downloads Plus is used to sell membership products using Wishlist Member, so you can sell membership levels and / or pay-per-posts as Easy Digital Downloads products. Easy Digital Downloads is the one responsible for the payment gateway integration and not Wishlist Member Easy Digital Downloads Plus nor Wishlist Member. All the aspects of payments and subscriptions are managed by the Easy Digital Downloads plugin and its extensions. Wishlist Member Easy Digital Downloads Plus does not interfere with any of these aspects and it is working behind the scenes only after a successful payment has been made. For more information on how to integrate WooCommerce with any of the payment gateways please check Easy Digital Downloads documentation.
