03

Create the order

Submit your clientOrderId, voucher, amount and customer delivery details.

create-order.ts 
import crypto from 'node:crypto';

const body = {
  clientOrderId: 'po_1001',
  voucherId: 171,

  email: 'buyer@example.com',
  phoneNumber: '+919876543210',
  ip: '203.0.113.4'
};

const payload = Buffer.from(JSON.stringify({
  timestamp: Date.now(),
  body
})).toString('base64');

const signature = crypto
  .createHmac('sha512', process.env.ZERO_FIAT_API_SECRET!)
  .update(payload)
  .digest('hex');

const order = await fetch(
  'https://api.0fiat.com/0fiat/api/v2/whitelabel/orders',

Partner economics

Turn checkout volume into a new revenue line.

Commercial terms are agreed during partner onboarding and can be tracked against the orders your integration originates.

Revenue share

Earn against eligible gift-card purchases generated by your product.

No integration licence fee

Scope the commercial model before launch without buying an API subscription.

Partner reporting

Reconcile orders, statuses and attributed activity from one integration.

Due diligence

Questions before production.

The answers that usually matter to product, engineering and compliance teams.

What does the B2B Gift Card API provide? +

It gives partner products a server-side path to browse available gift cards, request crypto quotes, create orders and follow delivery status without building the underlying catalog and payment orchestration.

Who is this designed for? +

Wallets, exchanges, fintech apps, dApps and AI products that want gift cards inside an existing user experience.

How quickly can we integrate? +

Timing depends on your interface, compliance needs and checkout model. The core integration follows familiar REST and HMAC-SHA512 patterns, and the 0fiat team can help scope the fastest path during onboarding.

How do we track an order? +

Use GET /v2/whitelabel/orderStatus?orderId={orderId} with the 0fiat order ID. If you want to reconcile against your own purchase reference, use GET /v2/whitelabel/clientOrderIdStatus?clientOrderId={clientOrderId}.

Which assets and networks are supported? +

The current catalog spans USDT and USDC across major networks including Ethereum, BNB Chain, TRON, Polygon, Solana and Base. Availability is pair-specific, so integrations should always read the live response before showing a payment option.

Do partners need to handle compliance? +

Requirements can vary by market, product and gift-card provider. 0fiat will clarify the applicable partner flow during onboarding; the API should not be presented as universally KYC-free.

Can the customer experience be white-labelled? +

Yes for API integrations: your product controls the interface while the API returns the catalog and transaction data required for the flow.

How do we get production access? +

Request partner access through 0fiat support. The team will confirm scope, credentials, current documentation and production requirements.
