Client Integration
Add the Uprails payment form to your frontend.
Step 1: Load the SDK
Add the Uprails SDK script to your HTML:
<script src="https://sdk.uprails.com/HyperLoader.js"></script>Sandbox Environment: For testing in sandbox, use https://sdk.sandbox.uprails.com/web/0.127.0/v1/HyperLoader.js instead.
Step 2: Initialize
const hyper = Hyper('pk_snd_YOUR_PUBLISHABLE_KEY');Step 3: Create the Payment Element
// Fetch client secret from your server
const { clientSecret } = await fetch('/create-payment', {
method: 'POST',
headers: { 'Content-Type': 'application/json' },
body: JSON.stringify({ amount: 5000, currency: 'USD' }),
}).then(r => r.json());
// Create the unified checkout
const unifiedCheckout = hyper.widgets({ clientSecret });
const paymentElement = unifiedCheckout.create('payment');
paymentElement.mount('#payment-element');Step 4: Handle Submission
const form = document.getElementById('payment-form');
form.addEventListener('submit', async (event) => {
event.preventDefault();
const { error, status } = await hyper.confirmPayment({
elements: unifiedCheckout,
confirmParams: {
return_url: 'https://yoursite.com/payment/complete',
},
});
if (error) {
// Show error to customer
console.error(error.message);
}
});Step 5: HTML Template
<form id="payment-form">
<div id="payment-element">
<!-- Uprails payment form will be inserted here -->
</div>
<button type="submit" id="submit-button">Pay</button>
<div id="error-message"></div>
</form>
