The checkout link generates a shareable URL that directs your customer to a payment page where they can make a one-time on-chain or lightning payment. To ensure that you can receive both on-chain and lightning payments, remember to keep the “BTC On-chain” payment method enabled in payment methods in Speed web application. You can request a checkout link in your preferred base currency in order to be paid in target cryptocurrency supported by the Speed platform API.
