In the general settings, you may stumble upon the payment integrations available with Leat. It is important to note that these integrations are exclusively for selling gift cards via the widget and contacts portal. They have nothing to do with any other integrations (POS or E-commerce for example).
They also have nothing to do with paying for your dashboard subscription as a business.
You should only set them up if you intend to sell gift cards specifically via the widget or contacts portal!
