Simple & Fast Payment Gateway Loader

The OnePay JavaScript SDK provides an easy and lightweight way to load and display available payment gateways in your application.

🔗 JavaScript SDK – Required Script

Include the SDK in your project:

<script src="https://one-pay.info/api/sdk.js"></script>

---

🚀 Usage Example

Load payment gateways using getPaymentMethods()

document.getElementById('loadPaymentMethods').addEventListener('click', function() {

    if (window.OnePayLib) {

        // Initialize the SDK using your Merchant API key
        // Paste here your merchant account id from one pay
        window.OnePayLib.initialize('<merchant id>');

        // Fetch available payment methods
        window.OnePayLib.getPaymentMethods()
            .then(methods => {
                console.log('Payment Methods:', methods);
            })
            .catch(error => {
                console.error('Error loading payment methods:', error);
            });

    } else {
        console.error('OnePay SDK is not loaded.');
    }

});
