Cartões-presente e eSIMs: use o endereço de e-mail do usuário final — por exemplo user@example.com.
Recargas móveis: use o número de telefone do destinatário no formato E.164, incluindo o + inicial e o código do país — por exemplo +14155551234.

A resposta inclui wallet_address and coin_amount. Compartilhe isso com seu usuário.

Rastrear pedido (API de stream)

GET/api/orders/{orderId}/subscribe

Implemente isso em duas partes obrigatórias: uma rota de proxy SSE do lado do servidor e um hook de stream do lado do cliente.

A rota da API recebe/api/orders/{orderId}/subscribe e encaminha para o upstream/v5/orders/{orderId}/subscribe.
O hook do cliente abreEventSource para a rota da API local, valida os payloads e reconecta com backoff quando necessário.

Código Essencial do Lado do Servidor

javascript

// app/api/orders/[orderId]/subscribe/route.ts
let upstream: Response;

try {
  upstream = await fetch(
    `https://api.cryptorefills.com/v5/orders/${params?.orderId}/subscribe`,
    {
      method: 'GET',
      headers: {
        ...(await genHeader.server(session)),
        'User-Agent': user_agent,
        Accept: 'text/event-stream',
        Connection: 'keep-alive',
      },
    },
  );
} catch (err) {
  return NextResponse.json(
    { error: 'Failed to connect to upstream stream' },
    { status: 502 },
  );
}

if (!upstream.ok || !upstream.body) {
  return NextResponse.json(
    { error: 'Upstream returned an error' },
    { status: upstream.status || 502 },
  );
}

// stream = ReadableStream that proxies upstream SSE events
return new Response(stream, {
  status: 200,
  headers: {
    'Content-Type': 'text/event-stream',
    'Cache-Control': 'no-cache, no-transform',
    Connection: 'keep-alive',
    'X-Accel-Buffering': 'no',
  },
});

Código Essencial do Lado do Cliente

javascript


const { data: lastEvent, error } = useSWRSubscription<TOrderSchema>(
  referenceOrderId ? `orders-info-stream-${referenceOrderId}` : null,
  ((key, { next }) => {
    let es: EventSource | null = null;
    let stopped = false;
    let shouldReconnect = true;
    let retryTimeout: number | null = null;
    let retryDelay = 1000;

    const cleanup = () => {

Rota neste repositório

app/api/orders/[orderId]/subscribe/route.ts

Lado do servidor (rota da API)

Usa cabeçalhos de servidor baseados em sessão viagenHeader.server(session), então chama o upstream${process.env.API_URL}/v5/orders/${params?.orderId}/subscribe. Em caso de falha de conexão, retorna502.

Lado do cliente (hook)

AbreEventSource para/api/orders/${referenceOrderId}/subscribe, valida cada payload comorderSchema.safeParse, manipulastop eventos e reconecta com backoff exponencial.

Rastrear pedido (polling)

GET/v5/orders/{orderId}

Abordagem de fallback: faça polling a cada 5-10 segundos até que o pagamento seja recebido. O código do cartão-presente aparece quando o status é 'Concluído'.

bash

curl -X GET 'https://api.cryptorefills.com/v5/orders/ord_abc123xyz' \
  -H 'Content-Type: application/json' \
  -H 'X-Cr-Application: YOUR_PARTNER_ID' \
  -H 'X-Cr-Version: YOUR_APP_VERSION' \
  -H 'X-Forwarded-For: END_USER_IP' \
  -H 'User-Agent: END_USER_AGENT'

Use polling quando

Você não pode manter uma conexão SSE aberta, ou seu ambiente cliente não suporta EventSource de forma confiável.

Estados típicos do pedido

AguardandoPagamento -> AguardandoEntrega -> Concluído

Created: Order has been created but no payment activity yet. Initial state right after checkout.
WaitingForPayment: Order is awaiting the customer's crypto payment. The payment window is open and countdown is running.
PaymentStarted: Customer has initiated a payment (transaction broadcast) but it hasn't been confirmed/received yet.
PartialPaymentStarted: A partial payment has been detected — the customer paid less than the required amount.
PaymentReceived: Payment has been received and confirmed on-chain, but delivery hasn't started yet.
WaitingForDelivery: Payment is confirmed; the order is queued for delivery.
WaitingForManualAction: Order requires manual intervention by the team (e.g. verification, supplier issue, edge case).
Done: Order is fully completed and delivered to the customer. Terminal success state.
Expired: Payment window elapsed without a valid payment being received. Terminal state.
PaymentFailed: The payment attempt failed (e.g. on-chain failure, rejected transaction).
PaymentSetupFailed: The payment couldn't even be set up (e.g. provider/quote failure before the user could pay).
Refunded: Order was refunded to the customer.
