How to Integrate QR Code Payments in 1C-Bitrix with SBP, Tinkoff, and YooKassa

When a customer places an order in an online store, they want to pay in two clicks — without entering card details.

A QR code on the payment page solves this: scan, confirm in the bank app, done. But under the hood, it's a mix of acquirer API, QR generation, status polling, and proper UX. We specialize in turnkey integrations for 1C-Bitrix and Bitrix24. With over 10 years of experience, we immediately spot bottlenecks. For example, on a project with an inventory of 150,000 SKUs, we implemented QR SBP via Tinkoff. The problem was that during peak loads of 100 concurrent orders, polling couldn't keep up with status updates, causing some payments to hang. We optimized by adding Bitrix agent queues and increasing the polling interval to 5 seconds with exponential backoff. As a result, 99.9% of payments completed correctly. A typical integration costs from 50,000 to 150,000 rubles, but pays for itself within 3 months through fee savings.

Types of QR Codes for Payment

QR SBP via the Faster Payments System

Works with any participating bank. According to Bank of Russia Regulation No. 580-P, transfers are credited within seconds. Fees are 0.4–0.7% of the amount — 3–5 times lower than card processing. With a monthly turnover of 1 million rubles, fee savings reach 40,000 rubles. This is the best option due to low fees and broad acceptance.

Bank QR — a proprietary format

Specific to a bank (SberPay QR, Tinkoff QR). Works only with that bank's app. Suitable for a single-brand audience.

QR as a link image

A regular link to the payment page encoded in a QR. Opens a mobile browser; the customer chooses a payment method on the site. Simpler to implement but adds an extra step.

QR SBP — the Optimal Choice for an Online Store

QR SBP wins on key parameters: fees 2–3 times lower than cards, instant money transfer, and easy refunds. For the customer, it's a familiar scenario: scan a QR in any banking app. According to statistics, 70% of users prefer SBP when available. Fee savings can reach 80% compared to cards. For example, with a monthly turnover of 500,000 rubles, savings amount to about 20,000 rubles; at 2 million rubles, it's 80,000 rubles.

How We Set Up QR Code Payment in 1C-Bitrix

How to Connect QR SBP via Tinkoff

First, create a payment in the acquirer via Init, get the PaymentId. Then request the QR code via GetQr. PHP code:

// Create a payment with QR type
$params = [
    'TerminalKey' => TINKOFF_TERMINAL,
    'Amount'      => (int)($order->getPrice() * 100),
    'OrderId'     => $order->getAccountNumber(),
    'Description' => 'Order #' . $order->getAccountNumber(),
    'NotificationURL' => '/local/tools/sale_ps_result.php',
    'PayType'     => 'O',
];
$params['Token'] = tinkoffSign($params, TINKOFF_SECRET);

$initResult = tinkoffPost('/v2/Init', $params);
$paymentId  = $initResult['PaymentId'];

// Request QR for SBP
$qrParams = [
    'TerminalKey' => TINKOFF_TERMINAL,
    'PaymentId'   => $paymentId,
    'DataType'    => 'IMAGE', // or 'PAYLOAD' to get a link string
];
$qrParams['Token'] = tinkoffSign($qrParams, TINKOFF_SECRET);

$qrResult = tinkoffPost('/v2/GetQr', $qrParams);
// $qrResult['Data'] — base64-encoded PNG with QR code (when DataType=IMAGE)
// or SBP link string (when DataType=PAYLOAD)

It's important to handle errors: if the payment isn't created, return a clear message to the user. We always add a fallback in case the acquirer API is unavailable, such as reserving the order and retrying with exponential backoff.

How to Implement QR SBP via YooKassa

YooKassa automatically generates a QR SBP when creating a payment with the sbp method:

$payment = $client->createPayment([
    'amount'          => ['value' => '1500.00', 'currency' => 'RUB'],
    'payment_method_data' => ['type' => 'sbp'],
    'confirmation'    => ['type' => 'qr'],
    'description'     => 'Order #' . $orderId,
], uniqid('', true));

$qrUrl = $payment->getConfirmation()->getConfirmationData();
// qrUrl — string like https://qr.nspk.ru/... — encode to QR on the client

To render the QR from a URL on the client, use the JS library qrcodejs or qr-code-styling. This is faster and doesn't load the server.

Displaying QR on the Page and Status Polling

// Show QR and poll payment status
async function showQRPayment(orderId) {
    const resp = await fetch('/api/get-payment-qr.php', {
        method: 'POST',
        body:   JSON.stringify({ orderId }),
    });
    const data = await resp.json();

    document.getElementById('qr-image').src = 'data:image/png;base64,' + data.qrBase64;
    document.getElementById('qr-block').style.display = 'block';

    // Polling: check status every 3 seconds
    const pollInterval = setInterval(async () => {
        const status = await checkPaymentStatus(orderId);
        if (status === 'paid') {
            clearInterval(pollInterval);
            window.location.href = '/payment/success/';
        }
        if (status === 'expired') {
            clearInterval(pollInterval);
            showExpiredMessage();
        }
    }, 3000);

    // Stop polling after 15 minutes
    setTimeout(() => clearInterval(pollInterval), 15 * 60 * 1000);
}

Server-side status check script with idempotency and transactional integrity:

// local/api/check-payment-status.php
$orderId   = (int)($_POST['orderId'] ?? 0);
$paymentId = getExternalPaymentId($orderId); // saved PaymentId from Tinkoff

$params = [
    'TerminalKey' => TINKOFF_TERMINAL,
    'PaymentId'   => $paymentId,
];
$params['Token'] = tinkoffSign($params, TINKOFF_SECRET);

$status = tinkoffPost('/v2/GetState', $params);

$map = [
    'CONFIRMED'      => 'paid',
    'CANCELED'       => 'cancelled',
    'DEADLINE_EXPIRED' => 'expired',
];

echo json_encode([
    'status' => $map[$status['Status']] ?? 'pending',
]);

Polling must be resilient: on network errors, retry with exponential backoff, and never block the UI. Additionally, implement a MySQL transaction lock when processing callback notifications to prevent duplicate payments.

Common Mistakes When Setting Up QR Payment

One frequent issue is a timeout when generating the QR via the acquirer API. If the acquirer doesn't respond within 10 seconds, you need a fallback: show an alternative payment method or retry the request with a 1-2 second interval. We set a timeout of at least 30 seconds for the Tinkoff API and check payment status in the background via agents.

Another common problem is lack of handling duplicate notifications. When the acquirer sends multiple callbacks, you must check the payment status in the database with a transactional lock before updating. Otherwise, an order could be paid twice. This is easily solved with a SELECT ... FOR UPDATE in MySQL.

How can you avoid typical mistakes when connecting payment systems on 1C-Bitrix?

The most common mistake during integration is forgetting about the callback. The customer paid for the order, the money was debited, but the status in b_sale_order did not update: the manager sees "Awaiting payment" and starts calling the client. The reason is an incorrect URL in the gateway settings or a handler that returns a 500 error for an atypical response structure. We offer services for connecting payment systems on 1C-Bitrix with full testing of all scenarios: successful payment, refusal, timeout, partial refund, duplicate callback.

Why are callbacks critical?

Each payment gateway sends a notification to your server. If the handler does not guarantee idempotency, a double call will lead to a double charge. We always implement a check by notification ID (external_id) and block repeated processing in \Bitrix\Sale\Order. It is also critical to set the callback URL in the aggregator's personal account – /bitrix/tools/sale_ps_result.php for the standard module. If you use a custom handler, we verify that it returns HTTP 200 even in case of parameter errors (the gateway should not repeat the request indefinitely).

use Bitrix\Sale\Order;
use Bitrix\Main\Application;

// Get notification data
$data = Application::getInstance()->getContext()->getRequest()->toArray();
// Check signature (depends on aggregator)
if (!checkSignature($data, 'SECRET_KEY')) {
    die('FAIL');
}
// Find order by external ID
$order = Order::loadByExternalId((int)$data['order_number']);
if ($order && $order->isPaid() === false) {
    $order->setField('PAYED', 'Y');
    $order->save();
}
echo 'OK';

How do we optimize payment flow for higher conversion?

How to choose a payment aggregator for 1C-Bitrix?

The choice of aggregator depends on the geography of customers, average order value, and need for installments. For Russia, the basic set is YooKassa (all main methods, fiscalization out of the box) and CloudPayments (widget on the page without redirect, Apple Pay). If you work with large corporate clients, add Sberbank (SberPay, SBP). For international sales, use Stripe or PayPal. We often use a two-tier scheme: main aggregator + backup (auto-switching on failure).

What payment gateways and methods do we use?

YooKassa

One contract – all main methods: Visa/MasterCard/MIR cards, YooMoney, SberPay, internet banking, installments. Fiscalization under 54-FZ out of the box (via the sale module). The standard handler /bitrix/modules/sale/handlers/paysystem/yandexpay/ covers basic scenarios. For holding (two-stage payment), subscriptions, or split payments, custom integration via YooKassa API v3. Callback is configured to /bitrix/tools/sale_ps_result.php, we parse notification and update \Bitrix\Sale\Order via setField('PAYED', 'Y').

CloudPayments

Focused on conversion: the payment widget directly on the checkout page, without redirect to an external domain. The customer does not leave the site – the abandonment rate during payment drops. It supports recurring payments (card tokenization via cryptogram), Apple Pay, and Google Pay. 3D Secure with intelligent routing – requested only for high fraud risk. Integration with Bitrix – via CloudPayments REST API and a custom handler in the sale module.

Tinkoff Payment

API integration via TinkoffPaymentAPI (ready-made module or manual implementation). QR code for payment via the app, "Tinkoff Credit" installment – critical for expensive goods. Partial refunds via the Cancel method – without calling the bank, everything from the Bitrix admin panel.

Sberbank (SberPay and SBP)

SberPay – payment via push notification or QR, SBP – commission 0.4–0.7% vs 1.5–2.5% for cards. This is a significant savings on volume. Holding via registerPreAuth / deposit API. Note that SberPay requires a separate agreement with the bank.

Apple Pay and Google Pay

Payment in two clicks, without entering card data. They are connected through an aggregator (YooKassa, CloudPayments, Tinkoff). Important nuances:

• Apple Pay requires domain verification: the file apple-developer-merchantid-domain-association in /.well-known/. Without it, the button will not appear.
• Button placement strictly according to Apple and Google guidelines – otherwise rejection in review.
• Fallback to the standard payment form if the device does not support contactless payment.

How do we handle installments, BNPL, and 54-FZ compliance?

If the average order value is above 30,000 RUB and conversion drops, installment removes the price barrier. We connect:

• Tinkoff Installment (3–24 months)
• Buy with Sber
• Mokka / Dolyami – BNPL: 4 payments, 0% for the buyer

Integration: widget with monthly payment calculation on the product card ("from 2,500 RUB/month"), order data transfer to the bank via API, status processing (approval, rejection, awaiting documents) in OnSaleStatusOrder handlers.

Fiscalization under 54-FZ is a mandatory requirement. The fine for a missing receipt is up to 100% of the payment amount. In accordance with Federal Law No. 54-FZ, an electronic receipt must be sent to the buyer. We connect ATOL Online, Orange Data, Module.Kassa, Evotor, Shtrikh-M. Setup in Bitrix – the "Cash Registers" section in the sale module:

• VAT rate, item and method of payment – an error in any field can lead to a fine during inspection.
• Receipts for prepayment and partial payment (two receipts: at payment and at shipment).
• Refund receipts upon cancellation via \Bitrix\Sale\Cashbox\Cashbox::addChecks().
• Monitoring: if the receipt is not sent, an alert to the manager.

When selling shoes, clothing, or perfumes, it is mandatory to transfer marking codes in the receipt. Integration with "Chestny ZNAK", scanning DataMatrix during order assembly, automatic removal from circulation upon sale via \Bitrix\Catalog\Product\Marking.

Payment support: refunds, multicurrency, security

Refunds

Full and partial refund without calling the bank – via the aggregator API (refund / cancel). The refund receipt is generated automatically, the order status is updated, the amount is recalculated, and the customer is notified. Timeframes: e-wallets and SBP – 1–3 days, bank card – up to 30 business days (depends on the issuing bank).

Multicurrency

Price types in b_catalog_price for each currency, rates via the Central Bank API (\Bitrix\Currency\CurrencyManager::updateCBRFRates()) or manual input. Conversion at the catalog level – the customer sees prices in their currency. For accepting dollars/euros, we connect Stripe, PayPal. We take into account conversion fees when calculating margin.

Security

Card data is processed on the certified gateway side (PCI DSS) – the card number never passes through your server. Anti-fraud at the aggregator level. Logging all events in b_sale_order_change for audit. Anomaly monitoring: transaction spike, atypical geography – alert.

How we work and estimated timelines

1. Analysis – what payment methods are needed, markets, transaction volume, current aggregator.
2. Solution selection – sometimes two aggregators are better than one: YooKassa as the main, CloudPayments as backup – if one fails, traffic goes to the second.
3. Integration – we test each scenario: successful payment, 3DS refusal, gateway timeout, double callback, partial refund.
4. Fiscalization – online cash register, checking the correctness of receipts on test orders.
5. Monitoring – alerts for gateway failures, conversion dashboard at the payment stage.

What is included in the work

• Full setup of selected payment systems in 1C-Bitrix: modules, handlers, callbacks, testing.
• Integration documentation (gateway operation scheme, handler description, logic).
• Training your manager to work with payment modules and refunds.
• Technical support during launch and the first 2 weeks of operation.
• Monitoring – we set up alerts for errors and conversion drops.
