Create invoice

Charges a fixed fiat amount against an asset on a specific network. The crypto amount is locked at creation via a rate quote — it never floats afterwards.

The hosted checkout redirects the customer to the success URL after payment, or to the cancel URL when the invoice expires, fails or is cancelled. Leave both empty to keep the customer on the checkout page.

Paying to the network: customers see the payment address, QR code and a network warning on the hosted checkout. Wrong-network or wrong-asset transfers are recorded but never credited.
