Developers · Hosted checkout
A ready-made checkout, live in an afternoon
Redirect customers to a hosted payment page that accepts cards, wallets, local rails and crypto — no PCI scope, no UI to build. It settles straight to your 1klas account.
What it does
Built to drop in
No PCI scope
The card data never touches your servers — we host the page and the compliance.
Every method, one page
Cards, wallets, local rails and crypto, arranged and localised for the payer.
Your branding
Logo, colours and domain — it reads as your checkout, not ours.
Webhooks for everything
A signed event for every payment, refund and payout to keep your system in sync.
How it works
Three steps to live
01
Create a session
One API call returns a hosted URL.
02
Redirect the customer
They pay on the page; you build no UI.
03
Get the webhook
A signed event confirms the payment — fulfil the order.
webhook.js
// Confirm the payment from the signed webhook
app.post("/webhooks/1klas", (req, res) => {
const e = klas.webhooks.verify(req) // checks the signature
if (e.type === "checkout.completed") {
fulfil(e.data.reference) // ship the order
}
res.sendStatus(200)
})
Better together
