Accept crypto payments in Next.js

Add non-custodial crypto checkout to your Next.js app: create an invoice, send the buyer to the hosted checkout, and fulfill on a signed webhook. Funds settle straight to your own wallet, $0 platform fees.

Install

npm install @shieldz/sdk

Create an invoice and redirect to checkout

// app/api/checkout/route.ts
import Shieldz from "@shieldz/sdk";
const shieldz = new Shieldz(process.env.SHIELDZ_API_KEY!);
export async function POST() {
  const invoice = await shieldz.invoices.create({ amount_usd_cents: 5000, memo: "Order" });
  return Response.redirect(invoice.pay_url, 303);
}

Verify the webhook

// app/api/webhooks/shieldz/route.ts
import { constructEvent } from "@shieldz/sdk";
export async function POST(req: Request) {
  const raw = await req.text();
  try {
    const event = await constructEvent(raw, req.headers.get("x-shieldz-signature") ?? "", process.env.SHIELDZ_WEBHOOK_SECRET!);
    if (event.type === "invoice.paid") { /* fulfill the order */ }
    return new Response("ok");
  } catch { return new Response("bad signature", { status: 400 }); }
}
