SixPay is a payment layer for merchants that want to accept supported on-chain assets without making wallet routing, quotes, payment intents, or order monitoring their storefront’s responsibility. The standard integration keeps payment facts authoritative on the merchant server:
  1. Create the merchant’s order.
  2. Create a SixPay checkout session from the merchant server.
  3. Open SixPay checkout in the browser with the short-lived session credentials.
  4. Complete the merchant order only after a verified SixPay webhook.

Start integration

Create a Merchant API Key and open the first session-backed checkout.

Choose an integration

For a normal merchant backend, checkout sessions are the default. Direct checkout is only a compatibility option for flows that have no merchant server and cannot safely use trusted item promotion pricing.
