Getting Started
Introduction
CoinFat lets your business accept crypto payments against prices in your own settlement currency, with no crypto addresses or exchange rates to manage on your side.
How integration works
Integration is server-to-server plus a hosted checkout redirect. Your backend creates an invoice, we return a hosted checkout_url, you redirect your customer there to pay in the coin they choose, and we notify your backend via a webhook when the invoice is paid, or expires, or is canceled.
You never touch wallet addresses, exchange rates, or on-chain confirmations. The hosted checkout and our infrastructure handle all of it.
What you build
Three things live on your side: a server call to create an invoice, a redirect to the checkout URL we return, and a webhook handler that verifies our signature and fulfills the order. Everything else is ours.
