Sell and automate

What you can do here

Choose manual issuance, WooCommerce or a verified backend to deliver licenses after confirmed purchases.

Start with manual issuance if you only want to send keys. Use the native WooCommerce connector for its combined import; advanced provider recipes require a trusted verification backend. KDPika platform billing is separate from your customer's purchase.
