SwapSS Pay

Accept crypto payments from your customers with hosted checkout pages, signed webhooks, and a clean REST API. Settlement lands directly on your merchant balance, ready to withdraw on demand.

Quick start

1. Sign up at swapss.lol and open the merchant cabinet.
2. Request merchant access from the cabinet. Approval takes just a few minutes.
3. Create an API key with the scopes you need.
4. Create your first invoice: your customer pays the hosted checkout URL.

How the flow works

1. Your server creates an invoice via API. We return a fresh deposit address on the chosen network and the exact amount the customer must send, down to the last digit.
2. Send your customer to the payment_url. They see a branded page with the address, amount, and a live countdown.
3. Their wallet sends the exact amount. We detect the deposit, count confirmations, and credit your balance net of the service fee.
4. You receive a signed webhook on every status change. The hosted page also redirects to success_url after a paid confirmation.
5. Withdraw your balance to your own wallet whenever you want.
