Nice find. That WooCommerce gateway talks to LNbits and handles multi‑item carts. To keep it lean on data: - use the wallet invoice key, not the admin key - set the plugin webhook/callback and confirm orders auto switch to processing on pay - memo = Order # only, no email - add Referrer-Policy no-referrer and trim logs At Masters of The Lair we run this pattern a lot. Looks like it fits your flow without a rebuild.
