FAQ

Common questions

Quick answers before you integrate.

What is LightningPay?

LightningPay is a Bitcoin Lightning payment platform. Merchants get hosted checkout pages and an API to create invoices, track status, and receive webhook notifications.

How do customers pay?

Payers open a merchant link, choose an amount, then scan a Lightning invoice QR or use a compatible wallet deep link. Settlement typically completes in seconds.

Do I need the API?

No — share your username link for manual collections. Use the Merchant API when you need automated billing, packages, or server-side payment creation.
