I never managed to make yours work. Lightning payment was never sent. It's also missing a few festure I need. I want the plugin to share revenu based on different products sales. Not ref link.. i have no idea how yours is supposed to function without adding an Lightning API like from blink. Maybe it was already directly in the plugin code? Either way I couldn't make mine work either.

For the price yours is not auite what I need either. I think. Yours change the btc amount based on a usd price. Me I want the usd displayed price to change while the rral price in btc stays the same.
