Create a session
Your server sends the amount and order. You get a link on your own domain to send the buyer to.

The checkout your gateway never built.
FlowFront runs on top of your API. Buyers pick a coin, a network and their wallet, and pay in one tap — on your domain, in your brand. Invoices, funds and compliance stay with you.

How it works
No adapters. One protocol your backend speaks in an afternoon.
Answer one request
When the buyer picks a coin, we call your deposit_url, signed. You create the invoice your way and return the address.
deposit.requested
{ "asset": "USDT/TRC20",
"amount": "49.90" }
→ { "address": "TQn9Y2…",
"amount": "53.89",
"reference": "inv_123" }Tell us the status
Post an event when the payment moves, or let us ask your status_url. The checkout updates by itself.

What's inside
Everything a checkout needs, nothing that touches money.
Your domain
pay.yourbrand.com with a CNAME and a TXT record. Session links use it as soon as it is verified.
Your brand, fully
Logos for light and dark, favicon, colours, corners, separate heading and text fonts — including your own font files. Text on your accent stays readable.
Live design preview
Change a colour in the console and watch the real checkout change next to it, screen by screen.
Wallet deep links
Ready transfers for 11 wallet apps, guidance for 3 exchanges, and a QR code any wallet can scan.
A console for your team
Payments with filters, test payments from a form, API keys, signing secret, domains and checkout defaults.
No custody, no licence
Addresses and amounts come from your API, unchanged. Funds go to your accounts. We never see a private key.

FAQ
Short answers.
Do you hold or route any funds?
No. Your API returns the address and amount; buyers pay to them directly. FlowFront only renders the page and passes statuses along.
Which providers does it work with?
Any that can return a deposit address for an invoice over an API. You map your currency codes to ours once — USDTT becomes USDT/TRC20, for example.
What if our invoices need the currency up front?
That is the usual case: the buyer picks first, then we call your deposit_url and you create the invoice in that currency.
How do statuses reach the page?
You post events as they happen. As a fallback we ask your status_url, only while the buyer has the page open.
Can merchants keep their own domain?
Yes. Each brand gets a FlowFront address on day one and can add its own, verified by DNS.
