My application integrates with Stripe, and I have been using Stripe checkout pages to load a gift card in the sandbox environment.
When a gift card is loaded from a third party this way and a buyer_payment_instrument_id is provided, does Square take a processing fee to load the gift card?
So in this example, Stripe would take their processing fee, and then Square would also take a processing fee?
Also, if a gift card is saved as a payment on file and the customer is using the gift card to pay for their purchase, will the business be charged any processing fees on that transaction?
