Developers

Built for engineers.

A clean, predictable REST API. Idempotent by default, signed webhooks, typed SDKs, and a sandbox that mirrors production.

Read the docs

create_payment.ts

// Create a payment intent
const intent = await nitro.payments.create({
  amount: 12_400,           // minor units
  currency: "EUR",
  customer: "cus_8f2c",
  description: "Order #4421",
  metadata: { order_id: "4421" },
});

// One-line redirect to hosted checkout
return Response.redirect(intent.checkout_url);

Idempotent by default

Every mutating request accepts an idempotency key. Network retries never double-charge.

Signed webhooks

HMAC-signed events with replay protection. Includes a test endpoint and a CLI to forward locally.

Typed SDKs

First-class TypeScript, Python, Go, and Ruby. Generated from the same OpenAPI spec our team uses.
