Documentação da API

Tudo para aceitar cripto com a AywaPay: crie faturas, envie pagamentos e valide callbacks.

Primeiros passos

  1. Solicite acesso (estamos em beta privado; o convite libera a criação da conta). Crie a conta e uma loja. Depois, ative a autenticação de dois fatores.
  2. Abra a aba API da loja e crie a chave secreta. Se quiser, permita apenas os IPs do seu servidor.
  3. Defina a Status URL da loja: é para lá que enviamos um POST a cada mudança de uma fatura.
  4. Crie faturas a partir do seu servidor e envie o cliente para o invoice_url retornado.

URL base

https://api.aywapay.com/api/v1

Autenticação

api_key vai como parâmetro de consulta em toda requisição. Nunca a exponha em um navegador ou aplicativo.

Toda resposta é em JSON: { "status": "success", "data": { … } } ou { "status": "error", "data": { "code": 103, "message": "…" } }.

Invoices

Create an invoice

GET/api/v1/invoices/new

ParameterDescription
api_key*Your store's secret key (Stores & API → API). Keep it on your server.

source_currency + source_amountFiat price, e.g. USD and 49.99. Converted at the current rate.
currency + amountOr a crypto price in one coin, e.g. BTC and 0.001. currency alone fixes the coin of a fiat invoice.

Callbacks (webhooks)

On every invoice status change we POST the invoice to its callback_url (or the store's Status URL). Withdrawals made with your API key are reported to the Status URL too, when they are sent, completed, fail or are cancelled. Add ?json=true to the URL to get JSON instead of a form post.

  • Answer with HTTP 200. Anything else is retried 8 more times over about two days, then shown as Failed in your dashboard.
  • Always check verify_hash before trusting a callback.
  • Stores & API → Webhooks shows every attempt, lets you resend one, and sends a signed test.

Validar a assinatura

verify_hash is an HMAC-SHA1 with your store's secret key: of PHP's serialize() of the key-sorted fields for form posts, or of JSON.stringify of the body without verify_hash for JSON.

PHP (form post)
<?php
// Your store's secret key (Stores & API → API)
$secretKey = getenv('AYWAPAY_SECRET_KEY');

$post = $_POST;                       // form-encoded callback
$received = $post['verify_hash'] ?? '';
unset($post['verify_hash']);
ksort($post);
$expected = hash_hmac('sha1', serialize($post), $secretKey);

if (!hash_equals($expected, $received)) {
    http_response_code(400);
    exit('bad signature');
}
if ($post['status'] === 'completed' || $post['status'] === 'mismatch') {
    // mark order $post['order_number'] as paid
}
http_response_code(200);
Node.js (JSON)
import crypto from "node:crypto";

// callback_url ends with ?json=true, so the body is JSON
app.post("/callback", express.json(), (req, res) => {
  const { verify_hash, ...body } = req.body;
  const expected = crypto
    .createHmac("sha1", process.env.AYWAPAY_SECRET_KEY)
    .update(JSON.stringify(body))
    .digest("hex");
  const given = Buffer.from(String(verify_hash ?? ""));
  const wanted = Buffer.from(expected);
  if (given.length !== wanted.length || !crypto.timingSafeEqual(given, wanted)) {
    return res.status(400).send("bad signature");
  }

  if (body.status === "completed" || body.status === "mismatch") {
    // mark order body.order_number as paid
  }
  res.sendStatus(200);
});

Modo de teste (sandbox)

Every store can have a test key next to its live key (Stores & API → API → Test key). It works with the same endpoints, with no real money:

  • Invoices made with the test key are test invoices: no deposit address, nothing on a blockchain.
  • Their payment page has Simulate buttons: paid, overpaid, underpaid, expire. Each fires your normal callback, with test=true and signed with the test key.
  • Test invoices never touch your balance. Withdrawals and deposit addresses need the live key (error 229); balances read 0.
  • Order numbers are separate: a test order never blocks a live one with the same number.
Create a test invoice
curl -G "https://api.aywapay.com/api/v1/invoices/new" \
  -d source_currency=USD -d source_amount=10 \
  -d order_number=test-1 -d order_name=Test \
  -d api_key=$AYWAPAY_TEST_KEY

Seu próprio domínio de pagamento (white label)

No plano White label, suas faturas, links de pagamento, páginas de doação e botões de pagamento podem abrir no seu próprio endereço, como pay.yourshop.com, em vez do nosso. Os clientes veem só o seu domínio e a sua marca. Basta um registro DNS e uns dez minutos, sem precisar de desenvolvedor.

Como configurar

  1. Mude a loja para o plano White label (loja → Geral).
  2. Abra a aba Página de pagamento da loja. Em “Onde os links de pagamento abrem”, escolha Meu próprio domínio.
  3. Digite um subdomínio seu, como pay.yourshop.com (não o próprio yourshop.com). Leia as taxas, se aparecerem, e salve.
  4. Copie o registro mostrado na tela e adicione-o onde o DNS do seu domínio é gerenciado (Cloudflare, GoDaddy, Namecheap, Hostinger etc.). O painel tem guias rápidos para cada um.
  5. Aguarde. Verificamos a cada minuto: DNS → Certificado HTTPS → No ar. Costuma levar de 5 a 30 minutos; registros DNS novos podem levar algumas horas. Avisamos por e-mail quando estiver no ar.

O registro DNS

TipoNomeValor
CNAMEpay<seu-código>.domains.aywapay.com

Copie o destino exato do seu painel: ele é único para a sua loja. A maioria dos provedores pede só a primeira parte (pay) como nome.

Usa a Cloudflare?

Defina o registro como “DNS only” (nuvem cinza). Com a nuvem laranja ligada, o certificado não pode ser emitido e a verificação informa que o registro está atrás do proxy.

Se a verificação não passar

  • Registro não encontrado: o CNAME ainda não existe ou o DNS ainda não se propagou. Confira o nome e aguarde alguns minutos.
  • Aponta para outro lugar: outro registro (A, AAAA ou um CNAME antigo) usa o mesmo nome. Apague-o e deixe só o CNAME.
  • Atrás do proxy: a nuvem laranja da Cloudflare está ligada. Mude o registro para “DNS only”.
  • Certificado pendente: o DNS está certo, e o certificado HTTPS costuma sair em poucos minutos.

Quando estiver no ar

  • Links novos e existentes abrem no seu domínio. Links já enviados com o nosso endereço continuam funcionando.
  • Você pode voltar ao link da AywaPay a qualquer momento com um clique; seu domínio fica salvo.
  • Se o seu DNS deixar de apontar para nós por 24 horas, os links voltam sozinhos para o nosso endereço e avisamos você por e-mail, então nenhum pagamento se perde.
  • Se a sua conta tiver taxas por domínio próprio, elas aparecem antes de salvar e são descontadas do seu saldo.
