Hi - I’m building my first php card-payment for a customer and have the web-payments-quickstart working but the default values for the VISA card (4111 1111 1111 1111, 07/25, 111, 07924 (my zip code)) result in a “Payment Failed” method.
I’m using http://localhost:3000/examples/card-payment as my address.
My code is as follows:
<!doctype html>
<html>
<head>
<link href="/app.css" rel="stylesheet" />
<script
type="text/javascript"
src="https://sandbox.web.squarecdn.com/v1/square.js"
></script>
<script>
const appId = 'sandbox-sq0idb-aw1FtqwNeZro48yfTz39OA';
const locationId = 'LFW5JTF75XRGJ';
async function initializeCard(payments) {
const card = await payments.card();
await card.attach('#card-container');
return card;
}
async function createPayment(token, verificationToken) {
const body = JSON.stringify({
locationId,
sourceId: token,
verificationToken,
idempotencyKey: window.crypto.randomUUID(),
});
const paymentResponse = await fetch('/payment', {
method: 'POST',
headers: {
'Content-Type': 'application/json',
},
body,
});
if (paymentResponse.ok) {
return paymentResponse.json();
}
const errorBody = await paymentResponse.text();
throw new Error(errorBody);
}
async function tokenize(paymentMethod) {
const tokenResult = await paymentMethod.tokenize();
if (tokenResult.status === 'OK') {
return tokenResult.token;
} else {
let errorMessage = `Tokenization failed with status: ${tokenResult.status}`;
if (tokenResult.errors) {
errorMessage += ` and errors: ${JSON.stringify(
tokenResult.errors,
)}`;
}
throw new Error(errorMessage);
}
}

};
const verificationResults = await payments.verifyBuyer(
token,
verificationDetails,
);
return verificationResults.token;
}
// status is either SUCCESS or FAILURE;
function displayPaymentResults(status) {
const statusContainer = document.getElementById(
'payment-status-container',
);
if (status === 'SUCCESS') {
statusContainer.classList.remove('is-failure');
statusContainer.classList.add('is-success');
} else {

statusContainer.classList.add('is-failure');
}
statusContainer.style.visibility = 'visible';
}
document.addEventListener('DOMContentLoaded', async function () {
if (!window.Square) {
throw new Error('Square.js failed to load properly');
}
let payments;
try {
payments = window.Square.payments(appId, locationId);
} catch {
const statusContainer = document.getElementById(
'payment-status-container',
);
statusContainer.className = 'missing-credentials';
statusContainer.style.visibility = 'visible';
return;
}
let card;
try {
card = await initializeCard(payments);
} catch (e) {
console.error('Initializing Card failed', e);
return;
}
async function handlePaymentMethodSubmission(event, card) {
event.preventDefault();
try {
// disable the submit button as we await tokenization and make a payment request.
cardButton.disabled = true;
const token = await tokenize(card);
const verificationToken = await verifyBuyer(payments, token);
const paymentResults = await createPayment(
token,
verificationToken,
);
displayPaymentResults('SUCCESS');
console.debug('Payment Success', paymentResults);
} catch (e) {
cardButton.disabled = false;
displayPaymentResults('FAILURE');
console.error(e.message);
}
}
const cardButton = document.getElementById('card-button');
cardButton.addEventListener('click', async function (event) {
await handlePaymentMethodSubmission(event, card);
});
});
</script>
</head>
<body>
<form id="payment-form">
<div id="card-container"></div>
<button id="card-button" type="button">Pay $1.00</button>
</form>
<div id="payment-status-container"></div>
</body>
</html>
How do I troubleshoot this?
Thanks for the help!
