The payment link is a shareable URL that directs your customer to a payment page where they can make an on-chain or a 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. A payment link can be shared and used multiple times to accept payments from your customers. You can generate a payment link in your preferred base currency in order to be paid in target cryptocurrency supported by the Speed platform API.
