Cuenta del beneficiario

Cada entrega debe incluir un beneficiary_account en su entregable, ahí es donde Cryptorefills entrega el producto. El formato requerido depende del tipo de producto.

Tarjetas de regalo y eSIMs: usa la dirección de correo electrónico del usuario final — por ejemplo user@example.com.
Recargas móviles: usa el número de teléfono del destinatario en formato E.164, incluyendo el + inicial y el código del país — por ejemplo +14155551234.

La respuesta incluye wallet_address and coin_amount. Comparte esto con tu usuario.

Rastrear pedido (API de stream)

GET/api/orders/{orderId}/subscribe

Implementa esto en dos piezas requeridas: una ruta de proxy SSE del lado del servidor y un hook de stream del lado del cliente.

La ruta de la API recibe/api/orders/{orderId}/subscribe y reenvía a upstream/v5/orders/{orderId}/subscribe.
El hook del cliente abreEventSource a la ruta de la API local, valida las cargas útiles y se reconecta con retroceso cuando sea necesario.

Código Esencial del Lado del 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 Esencial del Lado del 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 = () => {

        es.close();
        es = null;
      }
      if (retryTimeout !== null) {

        retryTimeout = null;
      }
    };

    const stopForever = () => {

      stopped = true;
      cleanup();
    };

    const connect = () => {

      es.addEventListener('message', (ev) => {
        try {
          const raw = JSON.parse(ev.data);
          const parsed = orderSchema.safeParse(raw);
          if (!parsed.success) return;

          next(null, parsed.data as TOrderSchema);
        } catch (err) {

Ruta en este repositorio

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

Lado del servidor (ruta de API)

Usa encabezados de servidor basados en sesión a través degenHeader.server(session), luego llama a upstream${process.env.API_URL}/v5/orders/${params?.orderId}/subscribe. En caso de fallo de conexión, devuelve502.

Lado del cliente (hook)

AbreEventSource a/api/orders/${referenceOrderId}/subscribe, valida cada carga útil conorderSchema.safeParse, manejastop eventos y se reconecta con retroceso exponencial.

Rastrear pedido (polling)

GET/v5/orders/{orderId}

Enfoque de respaldo: consulta cada 5-10 segundos hasta que se reciba el pago. El código de la tarjeta de regalo aparece cuando el estado es 'Hecho'.

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'

Usa polling cuando

No puedes mantener una conexión SSE abierta, o tu entorno cliente no soporta EventSource de manera confiable.

Estados típicos del pedido

WaitingForPayment -> WaitingForDelivery -> Done

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.

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.
