Begünstigtenkonto

Jede Lieferung muss ein beneficiary_account in ihrem Liefergegenstand enthalten, wo Cryptorefills das Produkt liefert. Das erforderliche Format hängt von der Art des Produkts ab.

Geschenkkarten und eSIMs: verwenden Sie die E-Mail-Adresse des Endbenutzers — zum Beispiel user@example.com.
Mobile Aufladungen: verwenden Sie die Telefonnummer des Empfängers im E.164-Format, einschließlich des führenden + und der Landesvorwahl — zum Beispiel +14155551234.

Antwort enthält wallet_address and coin_amount. Teilen Sie dies mit Ihrem Benutzer.

Bestellung verfolgen (Stream-API)

GET/api/orders/{orderId}/subscribe

Implementieren Sie dies in zwei erforderlichen Teilen: einer serverseitigen SSE-Proxy-Route und einem clientseitigen Stream-Hook.

API-Route empfängt/api/orders/{orderId}/subscribe und leitet an upstream weiter/v5/orders/{orderId}/subscribe.
Client-Hook öffnetEventSource zur lokalen API-Route, validiert Payloads und stellt bei Bedarf mit Backoff die Verbindung wieder her.

Serverseitiger Essentieller Code

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',
  },
});

Clientseitiger Essentieller Code

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

    const stopForever = () => {
      shouldReconnect = false;
      stopped = true;
      cleanup();
    };

    const connect = () => {
      if (stopped) return;
      cleanup();
      es = new EventSource(`/api/orders/${referenceOrderId}/subscribe`);

      es.addEventListener('message', (ev) => {
        try {
          const raw = JSON.parse(ev.data);
          const parsed = orderSchema.safeParse(raw);
          if (!parsed.success) return;
          retryDelay = 1000;
          next(null, parsed.data as TOrderSchema);
        } catch (err) {
          next(err as Error);
        }
      });

      es.addEventListener('stop', () => {
        stopForever();
      });

      es.onerror = () => {
        if (stopped || !shouldReconnect) return;
        cleanup();
        retryTimeout = window.setTimeout(() => {
          retryDelay = Math.min(retryDelay * 2, 30000);
          connect();
        }, retryDelay);
      };
    };

    connect();

    return () => {

Route in diesem Repo

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

Serverseite (API-Route)

Verwendet sitzungsbasierte Server-Header übergenHeader.server(session), ruft dann upstream auf${process.env.API_URL}/v5/orders/${params?.orderId}/subscribe. Bei Verbindungsfehler gibt es zurück502.

Clientseite (Hook)

ÖffnetEventSource zu/api/orders/${referenceOrderId}/subscribe, validiert jedes Payload mitorderSchema.safeParse, behandeltstop Ereignisse und stellt mit exponentiellem Backoff die Verbindung wieder her.

9b

Bestellung verfolgen (Polling)

GET/v5/orders/{orderId}

Fallback-Ansatz: alle 5-10 Sekunden abfragen, bis die Zahlung eingegangen ist. Der Geschenkkarten-Code erscheint, wenn der Status 'Fertig' ist.

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'

Polling verwenden, wenn

Sie können eine SSE-Verbindung nicht offen halten oder Ihre Client-Umgebung unterstützt EventSource nicht zuverlässig.

Typische Bestellzustände

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).
